Drones can perform a variety of tasks for business owners. They are used in roofing, construction, architecture, real estate and many other industries. One of the most popular uses is methane gas detection, and they can be equipped with thermal cameras to help detect leaks. This is especially useful for areas with wood, concrete, spray foam and PVC pipes. In this way, businesses can save money and avoid costly repairs.

A drone is a small, remote-controlled aircraft that can be outfitted with sensors and cameras for use in various applications. It is an alternative to traditional helicopters and planes for inspecting large and hard-to-reach areas. Drones are also much faster and safer than traditional methods. They can also collect data more quickly and provide better resolution images. This allows businesses to identify problems more accurately and reduce downtime.

For example, a drone equipped with a thermal camera can be sent to survey a section of a pipeline. This data can then be uploaded to a central location for analysis and reporting. In this way, companies can monitor the performance of a pipeline and identify potential problem areas before they become critical. This can help save time and resources, and it can also increase safety for employees working in hazardous environments.

Drones can also be used to conduct regular, frequent and comprehensive inspections of water quality. They can be equipped with a range of sensors, including multispectral, chemical and visual, to help monitor the health of vegetation and other water resources. This information empowers water resource managers to make informed decisions that optimize water distribution, identify areas vulnerable to drought and floods and develop conservation strategies.

Moreover, drones can be used to track water levels and monitor river and reservoir health. They can also be used to locate water leaks, resulting in significant cost savings for utilities. In addition, they can also be used to monitor erosion and sedimentation and assess the health of ecosystems. In fact, one company claims that its drones can outperform foot searches by up to five times, and they can be used in difficult or risky environments without compromising safety for staff.

LiDAR

LiDAR sensors fire a series of laser beams across a scene at extremely high rates. The distribution of energy that returns to the sensor is recorded as a waveform, with areas that appear brighter than others corresponding to objects on the ground (like branches or a building). This data can then be used to build a 3D model of the surface environment, known as a point cloud.

While traditional surveying methods for forests are time-consuming and often require the use of chainsaws, LiDAR is able to quickly and accurately map miles of forest like never before. This information can be incredibly useful to conservation efforts, as well as to the many industries that depend on the world’s trees for their products—from paper and syrup to furniture.

Specialized LiDAR systems mounted on drones or unmanned aerial vehicles can scan oil and gas facilities for methane leaks. These systems utilize Differential Absorption LiDAR to detect methane emissions by analyzing the absorption of laser light in the presence of methane. By identifying the locations of methane leaks, these systems can help operators improve operations and reduce environmental impact.

Mobile LiDAR scanning enables engineers to rapidly and efficiently acquire data on oil and gas facility infrastructure from the safety of their vehicle, reducing the need for expensive and hazardous field crews. This data is then used to create 3D models of storage tanks, pipelines, and processing plants to help engineers optimize facility design and maintenance. Regular mobile scans can also help engineers monitor changes in these facilities over time, detecting potential issues and assessing safety hazards.

The attributes of each lidar point vary depending on how the data was collected and processed. However, most points include x, y, and z positional values as well as light intensity. Light intensity values are especially helpful for highlighting surfaces such as impervious ground, low vegetation, buildings, and water.

Other attributes may be included in a point cloud, such as RGB (red, green, and blue) values, GPS time, scan angle, and scan direction. In addition, many vendors classify each point according to the type of surface that it reflected from—for example, low or high vegetation, building, or water.

Ultrasonic

A technique that uses ultrasonic waves to examine the integrity of mechanical structures without dismantling them. Changes in the material, such as holes, cracks and corrosion, cause differences in the impedance of sound waves that propagate through them, and these signals are detected by the sensors. This allows nondestructive testing to gather data on a number of structural aspects such as welded joints, petrochemical storage tanks and the quality of concrete poured at construction sites.

Ultrasonic NDT also works well for detecting compressed air and vacuum leaks in noisy industrial environments. Pressurized air leaks produce a high-frequency hiss that’s audible with a handheld ultrasound detector. This device allows operators to locate hissing sources and prioritize air leak repairs, even in the midst of production operations. The device is battery-powered and can be paired with headphones for use in noisy settings.

The use of ultrasound for cleaning and other applications has grown in recent years because it can remove contamination faster than traditional methods. Ultrasonic cleaning is used in the aerospace, automotive, sporting goods, printing, medical and pharmaceutical industries. It’s also a popular method for removing solder flux residue from circuit boards and other electronic devices. Ultrasonic waves generate cavitation that breaks the surface tension of liquids, resulting in increased molecular activity. This can accelerate certain chemical reactions, such as oxidation, reduction, dehydration and polymerization.

Another advantage of ultrasonic NDT is that it can detect corrosion in welded joints, a common source of leaks in pipe systems. This can help identify flaws before they become a safety risk and reduce the need for costly repairs. However, standard conventional ultrasonic NDT systems have several drawbacks such as limited testing distance and inflexible scanning mechanisms. Consequently, it’s often best to start with low-resolution ultrasonic NDT (LRUT) and then follow up with phased array ultrasound testing.

The PS-i handheld Ultrasonic Leak Detector is an excellent example of a portable ultrasonic leak detection system that’s ideal for industrial uses. It can easily find compressed air and vacuum leaks in noisy environments, and the user-friendly interface makes it easy to optimize sensitivity and detect small leaks.

Visual Inspection

Visual inspection is a simple and cost-effective technique for spotting leaks. It is often included in maintenance checklists and can be done using a variety of tools. Whether it is a simple pen and paper or more advanced software, visual inspection can help spot potential problems and make them easier to address before they lead to costly issues such as property damage and safety hazards.

Typically, visual inspections are non-destructive tests that look at the surface of an object to identify defects or flaws. They are commonly conducted in manufacturing, healthcare and energy industries. However, they can also be used to inspect infrastructure such as roads and bridges.

When it comes to leak detection, visual inspection can be used in conjunction with other methods such as thermal imaging or ultrasound. This allows technicians to perform a more comprehensive test and get a complete picture of an asset’s condition.

Homeowners can detect water leaks by observing damp spots, water stains or unexplained increases in water bills. Other methods of spotting a leak include monitoring water meter readings and using specialized acoustic devices to pinpoint the source.

In manufacturing, visual inspections can be used to identify assembly and cosmetic defects on the factory floor. This ensures that products and materials meet specific standards and requirements in quality control. Similarly, in the healthcare industry, visual inspections are vital for patient health and safety and ensure that equipment is working properly before patients undergo surgery.

In addition to reducing costs, visual inspections can also improve efficiency and reduce downtime. By allowing technicians to conduct inspections without the need to shut down machines, visual inspection can save valuable time and resources. However, it is important to remember that the scope of a visual inspection is limited and may miss some issues. Consequently, it is necessary to regularly review and update your inspection strategy to keep it up-to-date and effective. Moreover, it is essential to implement a procedure for reporting and recording any errors or downtime that are identified during an inspection. This will allow you to address these issues quickly and effectively, minimizing the impact on your organization’s bottom line.

Residential plumbing refers to the pipes, fixtures, and appliances that deliver clean water to homes and take wastewater away. It includes the main water line that brings in freshwater, the pipes that carry water to sinks, toilets, showers, and bathtubs, and the drainage system that removes wastewater and carries it to the sewer or septic tank. Residential plumbing also includes the water heater, which supplies hot water for washing, cleaning, and other household uses.

Plumbers can install a wide variety of residential plumbing fixtures and appliances, including dishwashers, washers, dryers, and more. They can also install water treatment systems to filter and treat home drinking water. These are typically installed in the main water line, although they can be installed at the fixture level as well.

When installing new plumbing, it is important to follow all local building codes and regulations. This ensures that the system is safe and will function properly. It is also important to carefully plan out the installation project before starting. This can help avoid costly mistakes and ensure that the new plumbing is compatible with existing systems.

One of the most common residential plumbing services is replacing or repairing drainpipes and faucets. Leaks and other problems with these components can cause serious damage if left unattended, so it’s important to have them fixed as soon as possible. A skilled plumber can quickly and efficiently repair or replace these parts to get the water flowing again.

Another important service residential plumbers provide is rerouting plumbing lines. This can be done when a home is being renovated or extended, and it can improve the flow of water throughout the house. It is essential to have a professional plumber do this work, as it requires knowledge of both construction and plumbing.

Residential plumbing can seem complicated, but it’s important to understand how the system works and what role each part plays. Plumbers can help make the process as smooth as possible by explaining what they’re doing and answering any questions you may have. This will help you feel confident in their work and know that your home is in good hands.

The repair process for residential plumbing involves fixing pipes, fixtures and other components in a household’s drainage system. Plumbers usually start by identifying the problem and consulting with the homeowner to come up with an appropriate solution. They may also recommend replacing old components, such as worn-out faucets and pipes, to prevent future problems from arising. This is one of the most common services provided by plumbing companies.

Aside from replacing and repairing damaged parts, residential plumbers are also responsible for maintaining the plumbing systems in their clients’ homes. This includes performing regular inspections to ensure that the pipes and fixtures are functioning properly. In addition, they may need to reroute water or gas lines when renovations or extensions are done on the house. They are also expected to keep up with the latest plumbing technologies and solutions to ensure that their clients’ homes are well-equipped.

Another service that residential plumbers provide is drain cleaning. This involves removing obstructions from the house’s drain lines to ensure that water and gas can flow freely. This is a necessary service for both residential and commercial buildings, as blockages can lead to serious damage in the long run.

Residential plumbing also includes installing and repairing fixtures such as sinks, tubs, toilets, showers and outdoor faucets. They also install and repair heating and cooling units to ensure that the temperature in a home is comfortable throughout the year. Some residential plumbers may even install laundry machines and dishwashers, depending on the needs of their clients’ households.

Unlike commercial plumbing, residential plumbing typically deals with smaller issues, such as leaky pipes and clogged drains. It’s easier to determine where these issues are coming from in a home, as residents use the plumbing fixtures regularly and would notice any small changes in water flow or running water. However, larger issues, such as sewer line damage, are more difficult to diagnose and require specialized equipment to solve.

If you’re experiencing any of these issues, it’s best to contact a reliable plumbing company right away. They will send a plumber to your home to perform a thorough assessment and find the source of the problem. Having these issues addressed early on can save you a lot of money in the long run and avoid costly repairs in the future.

When pipes in a home are damaged beyond repair, they may need to be replaced. This can be a daunting task for homeowners, but it is often more cost-effective than continually repairing aging or damaged pipes. Repiping your home can improve water pressure, eliminate leaks and clogs, and make appliances more efficient.

Residential plumbing systems are designed for single-family homes and have simpler layouts than commercial plumbing systems. Commercial spaces have higher daily usage and require larger water pipe sizes, as well as multipurpose fixtures and more complex drainage systems. This requires more extensive training and knowledge of building codes and regulations.

The lifespan of your pipes depends on a number of factors, including the materials they are made from and how well you maintain them. Most plumbers recommend that you get your pipes inspected regularly to determine if they need to be replaced. Older pipes are more likely to leak or break, while newer pipes are usually made of durable materials that can withstand greater wear and tear.

Depending on the type of pipes you have, they could last anywhere between 30 and 100 years. You can find out the age of your pipes by looking at your home inspection report or contacting your local water authority. Older pipes are more likely to have issues, especially if they are made of galvanized steel, which can corrode and leak over time.

A repipe is the process of replacing all of the water supply pipes in your house. This can be an excellent opportunity to upgrade your pipes to more durable materials, such as copper or PEX. It’s also a good time to consider adding water-saving fixtures, such as low-flow toilets and faucets.

The cost of a repipe can vary significantly, depending on the scope of work, materials needed, and labor hours. If the current pipes are buried underneath or behind walls, it will take more time and labor to gain access to them and install the new ones. You’ll also need to consider if you want your plumber to patch and repaint the drywall afterward.

Residential plumbing services include fixing clogged drains, leaking pipes and toilets as well as installing new fixtures. These are services that homeowners need to have done on a regular basis to ensure that their plumbing works as it should and prevents problems down the road such as water damage from faulty pipes or fixtures.

The most important function of any plumbing system is to provide a constant supply of fresh, clean water to the home’s fixtures and appliances. This is achieved by the water service line that comes into the house, the pipes that distribute water throughout the home’s rooms and the drainage system that removes waste and carries it to the sewer or septic system.

Because homes are smaller and have less use than commercial spaces, residential plumbing systems tend to wear out or become damaged more slowly than their counterparts in larger buildings. As a result, it can be easier to identify and repair issues with residential plumbing. However, this does not mean that there aren’t still challenges with residential plumbing.

In many cases, a homeowner’s plumbing problems are caused by a buildup of materials within the pipes that lead to the fixtures and appliances. This can include food particles, grease, hair strands and other debris that over time can cause blockages. A plumber that offers residential plumbing services will regularly check for this and remove any material before it can cause a full-on clog that may require pipe replacement.

One other factor that distinguishes residential plumbing from commercial is the fact that homeowners tend to be more vigilant about identifying and repairing small leaks and running toilets than they would in a commercial space. This is because they have a vested interest in keeping their homes safe and comfortable, as well as in minimizing the amount of money they spend on utility bills.

The differences between residential and commercial plumbing are not insurmountable, but they do exist. Familiarizing yourself with these distinctions can help you determine the type of plumber you need to hire for your home or business.

3 DIY Drain Cleaning Techniques

Plumbing Services No Comments

Drain Cleaning Philadelphia PA is an important part of maintaining a healthy home. When neglected, drain clogs can lead to serious plumbing problems.

Many homeowners use DIY solutions, such as plungers or chemical drain cleaners, to clear their clogs. However, these products can damage your home’s pipes and are often ineffective.

drain cleaning

If your clogged drains are keeping water from flowing properly, giving off foul odors, or are even backing up into your home’s plumbing fixtures, it may be time to call in the professionals for hydro jetting. Also known as power-washing for pipes, this technique uses powerful, pressurized water jets to remove stubborn debris and clogs from drains and sewer lines. The result is clean, smooth pipes that are free of obstructions and can handle regular use.

Hydro jetting is more effective than other drain cleaning techniques because it doesn’t just punch a hole through the clog but thoroughly cleans the interior of pipes. It’s also non-invasive, meaning that plumbers won’t have to dig up your yard or dig through the walls of your home to access the clogged line. The plumber simply inserts a hydrojetting hose with a specialized high-pressure nozzle into a drain or sewer cleanout. The jet of water is able to penetrate and wash away even the most stubborn blockages, including grease buildup.

It’s also useful for tackling tree roots that have invaded sewer lines, as the high-pressure water can break up and flush away root fragments. The best part about hydrojetting is that it doesn’t use any chemicals, which is a good thing for the environment and for your pipes. Chemical drain cleaners can eat away at your pipes and leave behind harmful residue, while their production and disposal contribute to greenhouse gas emissions that speed up global warming.

However, it’s important to note that hydrojetting should only be used by a professional plumber who has inspected your pipes to ensure they’re strong enough for this method. If your pipes are old or damaged, hydrojetting could actually damage them rather than clear the clog. Your plumber will be able to recommend other, more suitable drain cleaning methods in these cases. When done properly by a professional, hydrojetting is an effective way to clear stubborn drain clogs and prevent future ones from forming. Be sure to schedule regular drain cleaning services in your home to keep your pipes in top condition.

Chemical drain cleaners are a quick and easy solution to blocked or slow-draining pipes. They are poured down the drain in liquid, gel or powder form and react with organic material such as hair, grease, food waste and other debris to dissolve it and clear the clog. These chemicals are available at grocery stores, hardware stores, and big box retailers.

The main issue with using chemical drain cleaners is that they often work too well and can cause damage to your pipes. The acidic chemicals in these cleaners can corrode or dissolve metal pipes, especially older ones. They can also leave residue that eats away at the pipes, leading to holes and leaks. Finally, these cleaners can be dangerous to your health if they come into contact with your skin or eyes.

When used properly, liquid drain cleaners can be effective. However, many homeowners aren’t aware of the proper use or application of these products. When misused, they can release noxious fumes that can irritate your nose, throat and lungs. Long-term exposure can even lead to chemical burns and blindness.

Another concern with using chemical drain cleaners is that they can mask a deeper problem with your plumbing system. If the clog is caused by a broken pipe or sewer backup, it may take longer to dissolve and could require professional help to resolve.

If you must use liquid drain cleaners, be sure to follow the manufacturer’s instructions and keep children and pets away from the area. Also, be sure to wear gloves and eye protection when handling the product, and always ventilate the room well. Finally, never mix chemical drain cleaners, as this can create dangerous reactions.

If you’re struggling with a stubborn clog, try using a plunger first to see if it can dislodge the obstruction. If not, it’s time to call a plumber. They can use more advanced methods to get the job done quickly and safely. And don’t forget to ask about preventing future clogs by using a preventative maintenance plan. For more information, give us a call!

Drain snakes and augers are the next step up from a plunger for larger clogs. They are thin, flexible metal cables that are coiled into a protective drum and then used to push or “punch” through a clog and pull it out of the pipe. They’re available in manual crank or electric motor versions, depending on the size of the job.

First, make sure the clog is not in the p-trap (the curved piece of pipe under the sink). If it is, you’ll need to remove it before starting snaking. If the clog is farther down in the pipes, then you’ll need to remove any fixtures like toilets or showers that might get in the way of your snaking effort. Once you’re ready to start, insert the slender cable into the drain. If the clog is in the toilet, then it’s important to remove the toilet bowl lid first so you can reach down inside to break up the clog.

When you push the slender snake into the drain, you’ll feel resistance as it goes through the clog. If you feel this resistance subside, then you’ve likely dislodged or broken up most of the clog. If you don’t, then you’ll need to keep cranking the handle until the clog is gone. After the clog is removed, it’s important to flush the sink drain with full force for several minutes. This will wash away any remaining clog material and make it easier for you to use the snake again.

A plumbing snake is a good choice for most bathroom drains, showers, and toilets, as well as kitchen sinks and garbage disposals. If you have a really stubborn clog, though, then a toilet auger is the right tool for the job. This is an inexpensive, manually-cranked snake that’s specifically designed to clear toilet clogs. It’s also a good idea to have one of these handy just in case of an unexpected toilet stoppage. You can also find these in the tool aisle at most home improvement stores. However, for a serious sewer clog, it’s best to call in the professionals.

Drains can get clogged with hair, soap scum, oil, grease and other junk that can make it impossible for wastewater to flow through. If the problem gets bad enough, you may need a professional to clean out the pipes. A plumber can use a variety of tools to clean out the clog, including plungers, snakes or hydro jets. But before you run to the hardware store for chemical drain cleaners, consider trying one of these DIY techniques.

The simplest way to unclog a drain is with something you probably already have at home: baking soda and vinegar. This simple mixture is cheap, effective and safer for your pipes than most chemical-based cleaners. Plus, it’s environmentally friendly.

To make the mixture, start by removing any visible hair or debris from the drain opening. Then pour in about 1/2 cup of baking soda. Follow this with about 1/2 cup of vinegar. Let the mixture sit for about 30 minutes, then pour in some boiling water. Be sure to plug the drain with a stopper or rag to keep the hot water from splashing out of the pipe.

Another homemade and natural drain cleaner is liquid dishwashing detergent. It’s inexpensive and works well on many different kinds of clogs, but you have to be careful not to overuse it as too much can damage your pipes. Pour about 1/4 cup of the solution down your drain, wait for it to work its magic and then rinse with warm water.

Some homeowners also choose to use a snake, which is long, flexible cable wire with sharp hooks that can dislodge tough blockages. While this isn’t as fast as a drain auger, it’s cheaper and safer than chemical-based cleaners.

Other homeowners prefer biological drain cleaners, which use bacteria to break down clogs. They’re slower to work than chemical-based cleaners and can require repeated treatments, but they’re healthier for your pipes and the environment. And, of course, there’s always the good old-fashioned plunger. It’s easy to use, effective, and can be bought at most hardware stores. Using these drain cleaning methods can help you avoid expensive plumbing repairs in the future.

Water Heater Installation Tips

Plumbing Services No Comments

Water heaters are among the most essential household appliances. It is important that you know how to handle yours properly, from ensuring safety and efficiency to making sure you are up to code.

Water Heater Installation

Be sure to shut off the gas and water supply before working on a water heater. Also, drain the old unit before you remove it. For professional assistance, contact Water Heater Installation Denver now!

If you’re a homeowner who is handy with home improvement projects, a water heater installation is a relatively simple DIY task that can save you money. You can find a tank-style water heater at your local hardware store, and mounting it to the wall is easy enough. Just be sure to follow the printed instructions and safety warnings, which are also included with your new unit. Before you start work, check your water heater’s data plate to make sure it matches your home’s voltage, circuit breaker size, and plumbing connections.

Before you mount the tank, remove your existing water heater by unscrewing it from its vent hood and disconnecting the hot and cold water pipes with a tube cutter or pipe wrench. Then, reposition the vent shaft and draft hood to match the position of your new water heater. Before you reconnect any of the water lines, open every hot water outlet in your home and run water through them to clear out any debris that may be clogging them.

Connect the new cold and hot water pipes to the copper adapters on the top of your new water heater. If your city requires it or you have hard water, add short, plastic-lined nipples to shield your plumbing from galvanic corrosion. Solder these nipples to the copper pipes by using a soldering iron and a soldering kit, which is available at most hardware stores.

After you’ve connected the new water pipes, screw the copper adapters to their ports on the top of your new water heater. Using the label tags or pictures from the old setup as a guide, make sure you connect the wires to the correct terminals on the junction box. You can also check the water heater’s data plate to ensure the wire sizes and colors are correct.

Before you turn on the power to the water heater, shut off your house’s main gas valve by turning off the meter and moving the valve to the “Off” position. Also, turn off the electrical connections by switching the breaker to the “Off” position. Then, drain the water heater by opening the drain valve on the bottom of your tank.

Checking for Leaks

Water heater leaks aren’t always easy to locate. They can be hidden behind the insulating blanket and difficult to see when there’s a puddle around the unit. If a leak is found, it’s important to take the necessary steps to fix it quickly. This will prevent the water from leaking into areas where it’s not supposed to go, causing damage and leaving you with expensive repairs.

Leaks are often the result of failed components or rust in the tank itself. However, the leaks can also be caused by a number of other things such as the pipes, fittings, or a faulty drain valve. Depending on where the leaks are coming from, it may be necessary to replace your water heater.

If the leaking water is originating from the top of the tank, it’s probably due to excessive pressure in the cold water supply lines. The water supply pipes feeding into the tank are usually connected by metal tubing which can be susceptible to corrosion over time. The water pressure is controlled at the outside water meter and can sometimes be over 100 pounds per square inch (psi). This excess pressure can create excess stress on the metal of the tubing and cause leaks.

A leak from the bottom of the tank is most likely due to the drain valve. This is commonly a copper pipe with a spigot on the top that resembles a garden hose valve. This can be easily fixed by replacing the drain valve, which is usually relatively inexpensive.

Another common leak point is the temperature and pressure relief valve (TPR Valve). This is located on the top of the tank and is typically a copper tube with an on/off spout that looks just like the spigot on your garden hose. If this valve is leaking, it’s important to replace it immediately.

Gas leaks from a water heater are extremely dangerous and must be dealt with right away. If you suspect a gas leak, shut off your water supply at the main valve to your home and open a hot and cold faucet in an upstairs room that’s closest to the system. This will allow you to drain the water heater and lower the gas pressure in your house.

Checking for Rebates

Water heaters are one of the most important home appliances, but they’re also often ignored – until they break down. Attempting to replace a water heater without professional help can cost you big bucks in repairs and energy costs. It can also be dangerous because improper installation could lead to carbon monoxide leaks and a host of other problems.

Thankfully, it’s not impossible for a handy homeowner to install an electric water heater. That said, we don’t recommend DIYers do it. If you’re not a plumber, you could wind up with a giant mess and a water heater that doesn’t work properly. Plus, you’ll likely spend more money hiring someone to do it than you would have if you just paid for an expert.

If you are installing a new gas water heater, it’s important to check for rebates before purchasing. Many areas have programs that provide cash back for appliances that meet specific energy efficiency standards, usually tied to the ENERGY STAR program. These programs are meant to encourage consumers to purchase energy efficient appliances that save them money and reduce their environmental impact.

Gas tankless water heaters are popular as replacements for old storage models because they save up to 50% on energy expenses. They also cut water heating costs by only heating water when it’s needed. The first step in sizing a gas tankless water heater is to determine your peak hour usage. This is when you and your family use the most hot water, such as during showers and washing dishes.

Once you know your peak hour usage, you can size a tankless water heater by using the first-hour rating (FHR). The FHR is a number that tells you how many gallons of hot water the unit can produce in an hour.

If you’re planning to install an ENERGY STAR certified gas tankless water heater, you can get a $100 rebate plus $1.25 per gallon capacity. You can also receive a $50 rebate for converting from an electric to a gas water heater. To qualify for the rebate, you must buy and have your new gas water heater installed in your house before August 1, 2023.

Checking for Safety

If you have a gas water heater, be sure it’s properly installed and that there are no leaks. Likewise, make sure your electric water heater has a working temperature and pressure relief valve. This can prevent damage if the tank or pipes overheat.

Figure out how much hot water you use during peak times, then choose a heater with a capacity slightly larger than your estimated usage. This will ensure that you have enough hot water available at all times, including during a busy shower or washing machine cycle.

Remove the electrical cover plate at the top of your old water heater. Disconnect the black and white wires, then mark them with pieces of tape so you know where to connect them to your new heater. Remove the cover from the junction box at the top of your electric water heater and unscrew the wire connectors. Connect the new heater’s wires to the circuit breaker using the same procedure.

If your heater has a flue, check that there’s a good draft. A good draft will draw combustion fumes up through the vent pipe and out of your house. If not, these fumes could leak into your home and cause a deadly carbon monoxide poisoning.

Install a shut-off valve before and after your water heater. This will let you shut off the water supply to the heater for maintenance without cutting off water to the rest of your home. Opt for a copper valve to help keep your water clean and to avoid galvanic corrosion.

Before you switch over to your new water heater, purge air in your house by opening hot and cold taps positioned closest to the system’s lowest point. This will drain the remaining water and relieve pressure in your pipes.

Move the new water heater into place, connecting it to your existing piping as needed. For example, you might need to solder in a few elbows or offset the line to the new heater with pairs of 45-degree elbows. You’ll also want to solder in dielectric unions, which will let you disconnect the water heater for maintenance or repairs without having to cut and solder pipes.
