Tankless Water Heater Repair

Ignition failure on gas tankless water heaters can occur due to several issues. Check that the gas valve is open, there are no leaks, and you have paid your gas bill. Also, check the igniter and flame sensor to ensure they are not clogged with dirt, debris, or corrosion. For professional help, contact Tankless Water Heater Repair Denver.

The water temperature of your tankless water heater should be consistent and within a safe range to prevent scalding. However, if you experience excessively hot or cold water, this is a sign that the unit has a malfunctioning thermostat or temperature sensor. To resolve this issue, consult the manufacturer’s manual for troubleshooting steps for your model. If the problem persists, consult a professional to inspect and repair the unit.

Another common issue is a leaking tankless water heater. This can occur due to loose connections or attachments, corrosion, or damage to the unit’s pressure relief valve or heat exchanger. If you suspect a leak, shut off power to the unit by switching off the circuit breaker. Then, thoroughly inspect the unit for visible signs of a leak and tighten any loose connections or attachments.

If you notice an odor or sediment in your tankless water, it’s likely due to mineral buildup in the unit. This can be prevented by performing regular maintenance, including flushing the unit and removing accumulated minerals. It’s also recommended to use a water filter or softener to reduce the amount of sediment in your home’s water supply.

One of the most frustrating issues is a sudden burst of cold water during a shower or soak. This issue is referred to as “cold water sandwich.” It’s usually caused by a pressure-balancing valve that opens or closes based on the flow of your plumbing system. To resolve this issue, make sure the valve is properly adjusted and perform regular maintenance, such as cleaning the inlet filter. You should also consult your water heater’s owner manual for more troubleshooting tips.

Low Water Pressure

Tankless water heaters are a great way to save energy by heating your water only when it is needed, but they can have issues just like any other appliance. Understanding these problems can help you troubleshoot them and resolve them effectively.

One of the most common issues with tankless water heaters is low water pressure. This can be caused by a number of factors, including blockages in the plumbing system or inadequate water supply. It can also be a result of a clogged aerator or filter. To address this issue, simply unclog the aerator or filter by turning it off and then removing it from the faucet. Next, rinse the aerator or filter with hot water and scrub it clean with a brush. You can then replace the aerator or filter, which should restore water flow and pressure.

Another potential cause of low water pressure is a clogged heat exchanger. This can occur when mineral deposits build up and interfere with the heat regulation process. To resolve this problem, you will need to drain and flush the heat exchanger according to the manufacturer’s instructions.

A blocked exhaust can also inhibit proper ventilation and lead to carbon monoxide buildup, which is a serious safety concern. To prevent this from happening, make sure there is adequate gas pressure coming to the unit and that the gas valve is open. Also, check the venting system for obstructions and ensure that it is properly installed.

Finally, if the water heater is electric, check the power supply to determine whether it has been turned off or tripped. If so, reset the breaker or contact an electrician to fix the problem.


While some noise is normal for tankless water heaters, excessive noise can be a sign of an underlying issue. For example, humming or tickling sounds may be caused by fluctuations in water temperature and pressure, while crackling noises are common in gas water heaters due to burner condensation. If you hear jet engine-like noises, however, this is a serious problem that requires professional assistance.

One possible cause of these noises is that parts are loose, causing them to rattle and bang around inside the unit. This can be fixed by turning off the power to the tankless water heater and carefully inspecting it for loose components. If you find any, tighten them as much as possible. Another potential source of noise is a clogged air filter, which can be cleaned by following the manufacturer’s instructions for your unit.

You may also hear a tapping or ticking sound from heat traps and check valves. These are designed to encourage water flow in the proper direction and help prevent water backflow. If the noise is bothersome to you, it’s a good idea to replace the heat trap with a dielectric nipple to reduce the amount of ticking and tapping you hear.

Regular maintenance, including flushing out sediments, can also help reduce noise from your tankless water heater. In addition, it’s a good idea to consider installing soundproofing materials in the room where your tankless water heater is located to minimize noise levels. By being aware of these signs and seeking prompt repairs when needed, you can extend the life of your tankless water heater and ensure optimal performance.

Discolored Water

A common issue with tankless water heaters that require repair is discolored water. This can occur for a variety of reasons, including sediment or rust buildup. It can also occur if the hot water supply has been disrupted. If this happens, running the hot and cold faucets for a few minutes will usually clear up the problem. If the water is still discolored after a few minutes, it may be a sign that a gas leak has occurred. In this case, the best solution is to contact a professional plumber for safe, effective repairs.

Discolored water or unpleasant odors can also indicate the presence of bacteria in your tankless water heater. Flushing the unit can help eliminate these issues by removing minerals and impurities that have accumulated in the system. In some cases, the use of a water softener can further reduce mineral content, improving water quality and eliminating odors.

If the burner is failing to ignite, a number of troubleshooting steps can be taken. First, it is important to make sure that the gas valves are fully open. It is also recommended to clean the igniter and flame sensor using a brush or cloth. If these steps don’t work, it may be necessary to replace the components. In this case, it is important to consult the manufacturer’s instructions or a professional for guidance on replacement procedures.

Lastly, it is also important to check that the exhaust vents are clear of obstructions. Objects such as rats, birds, sticks, or dirt can block the flow of gas and cause the burner to fail to ignite. Performing an inspection of the exhaust pipes can often identify the source of the problem and help you find a quick, safe solution.


If your tankless water heater begins to produce discolored or unpleasant-smelling water, it’s a good idea to call a professional. These symptoms are often a warning sign that your unit has become contaminated with sediment or rust. Fortunately, you can usually resolve this issue by flushing the system. This involves disconnecting the water supply, opening the gas valve, and allowing the unit to flush for several minutes. You should also clean the burner and igniter regularly to prevent dirt from hindering ignition.

If you notice a rotten egg odor coming from your hot water, it’s likely a sign of hydrogen sulfide. The odor is produced by the sacrificial anode rod, which is typically made of magnesium or zinc, to attract corrosive minerals to it, thus preventing corrosion of the inner glass lining of the water heater. When the anode corrodes, it produces sulfuric acid that generates hydrogen sulfide.

The smell of rotten eggs may also be caused by stagnation in the water heater tank. This is often resolved by using a store-bought peroxide solution.

In electric tankless water heaters, the main electrical issues that can arise include power failure, tripped circuit breaker, and faulty heating element or burner. You can typically restore power to the unit by checking the circuit breaker and resetting it. You should also check the cold-water supply valve to ensure it’s open. If the water heater continues to fail, you should consult your user manual for further troubleshooting guidance. If you’re experiencing any of the above issues, contact us for a professional inspection and Tankless Water Heater Repair. Our service professionals can quickly and effectively identify the underlying cause of your water heater problems to ensure you’re getting consistent, high-quality hot water.

Preventive Pipe Maintenance Basics

When you find leaks in your plumbing pipes, check out these symptoms to determine whether you need preventive pipe maintenance:

Noise from septic pipes can signify the need for preventive pipe maintenance as well. There are many reasons why pipes might become noisy. Possible water in the kitchen could leak onto the sewer line, which might cause a clog to develop. Pipes located outdoors will also require maintenance to keep them free of ice and snow that might cause freezing. The ice that forms on pipes causes blockages, which results in water not flowing through them properly. Preventive maintenance is important to make sure that pipes are not damaged or blocked.

Leakage from storm drains can occur when there is no maintenance to prevent this. Water that is left in the pipes will eventually freeze, and when it does, the freeze can expand to the point where it breaks through a blockage. This type of damage needs immediate attention because pipes may need to be repaired. The professional Plumber Arlington can repair leaking sewer pipes, and this is a necessary part of preventive pipe maintenance to avoid future problems.

Clogged drains are another issue that might require maintenance. There can be a variety of reasons why sewage pipes become clogged. One reason is that people often leave large amounts of food and garbage in the toilet bowl. Another reason is that people frequently wash their hands in the sink, which rinses out the sink trap area. If you want to make sure that your sewage system is working properly, you should have it cleaned out every six months.

Keeping Your Drain Pipes Clean: A few good reasons for having a professional company clean out your pipes are to avoid costly repairs, to keep major debris and buildup out of your drains, and to prevent leaks. Many different methods are used to clean out pipes. Some people use warm soapy water, while others use specialized chemicals. In some cases, your local plumber can recommend a specific type of cleaning or preventive pipe maintenance that will help keep your drains running efficiently. You should also ensure that you have a professional periodically inspect your drains for leaks, cracks, and clogs.

Preventing Cracks and Bursts: One way to avoid large burst pipe situations is by using hydraulics to detect problems before they become serious. Using hydraulics, a professional can quickly locate areas where your plumbing is leaking, which will help them repair the problem before it gets worse. This is one of the main reasons you need to have your pipes inspected and serviced regularly.

Pulling a Trenchless Technique From a Disadvantaged Sewer Repair Technique: If your old pipe repair methods aren’t working very well, or if your plumber can’t seem to help, you may need to pull out a trenchless technique from a new sewer pipe cleaning procedure. The trenchless technique involves using hydraulic pressure to break apart the clog inside your drains and pipes by extracting the debris through smaller diameter pipes. Your new pipe cleaner will more than likely need to pull out a section of the old pipe along with the broken section to complete the repair. Although this new pipe cleaner may be a bit expensive to install, it will save you in the long run because you won’t have to replace any pipes in your home. This prevention method can sometimes be more effective than using an augmentation kit on your burst pipe situation.

Improper Relining and Leak Detection: While most people are aware that old and worn pipes should be replaced at regular intervals, not all homeowners are experts on these pipe sealing and relining procedures. Sometimes older plumbing materials can be difficult to detect when they are leaking. In addition, depending on the material that your house is constructed from, relining materials may not properly penetrate the lining. As a result, the homeowner replaces their pipes without the best results in the long run.
