Why My Water Heater Makes Sounds and How to Stop It

If your water heater is making some strange sounds, you don’t have to panic. The first thing for you to do in order to fix the problem is to identify the source of the problem.

Common reasons why you’ll hear water heater noise and how to fix them

Changes in Water Pressure

Changes in water pressure are quite common but, unknown to many, they are a leading cause for water heater noise.

Normally, it is the pipes that cause this as opposed to a water heater. If you hear a ticking sound, this is an indication that the heat trap could be having some problems.

This occurs because of fluctuation of water pressure.

How to fix it

In such a situation, you need to identify where the noise is coming from. Identifying the source of the sound will help you to fix the problem in the best way possible.

Try tightening the loose straps. After tightening the straps, you can now listen again to hear if there is more noise coming from there.

If you can still hear the ticking sound, consider installing spacers so that you prevent the pipes from being in motion. Something else you can do to fix the problem is to reduce the temperature of the water by some degree.

This will limit the ability of the pipes to expand a lot. With the above-mentioned tricks, you’ll be able to fix the sound of a water heater that comes as a result of changes in water pressure.

Constrained Water Flow

If something that should be flowing is restricted, chances are high that there will be a problem.

This is what happens when water is restricted from flowing. Usually, it is valves that control the flow of water.

If there is restriction of the valves such that they’re not able to allow water to flow, you’ll hear sounds from your water heater. There are particular valves that contribute to the production of the screeching sound.

How to fix it

One of these valves is the inlet valve. If the inlet valve is not opened fully, there are high chances that your water hear will begin to making noise. Of course, if it’s not opened fully, this means that there will be restriction of water flow, and this is what causes you to hear the sound.

If this is the case, you need to ensure that it’s opened fully. Another valve is the T&P relief valve. This is the temperature and pressure valve.

You can also refer to it as the safety valve. The purpose of this valve is to give way for water if there is too much pressure inside the tank. If you suspect that this valve could be the problem, the best thing to do is to shut the power to your heater and inform a plumber to take care of the issue.

Moreover, you can also check the outlet valve if you you’re still hearing the sounds. Ensure that the outlet valve is opened.

Clogging In the Tank

Another problem that could lead to water heater noise is clogging in the tank. Any unnecessary accumulation of materials leads to the malfunction of machines.

This is the same when it comes to your water heater. When there’s build up of minerals and other materials, it will, definitely, not function as it should. This is a leading cause of water heater noise.

It’s important to take note that accumulation of sediment can cause a lot of problems for your tank. It can even make it difficult to flush it. This could even force you to do a replacement.

As the temperature inside the tank increases, you’ll most likely hear a rumbling noise. As the water passes through the clogged surface, it will make the rumbling noise.

The more the clogging increases, the higher the noise. This means that the build-up is at a level where action should be taken.

How to fix it

If there is clogging in your tank, what you need to do is to flush your tank and drain it. Make sure that you remove the mud as well. This should help you address the problem effectively.

Condensation Problems

Condensation problems are also known to cause strange noises from water heaters. If you hear a sizzling sound from your water heater, this could be a condensation issue.

Once the water heats, condensation takes place. This could cause the water to drip to the burners. Normally, this is an indication of leakage in the tank. For you to fix this issue, it’s prudent to call your plumber since it can be a bit technical to do it yourself.

How to fix it

Indeed,water heater noisecan beextremely annoying as well as worrying especially if you don’t know what to do about it. However, if you understand these noises, it makes it easier for you to deal with the problem.

It will really save you a considerable amount of time if you know how to identify the source of the noise coming from your water heater.

For you to make sure that you keep your water heater in good shape and functionality for a long time, it’s advisable that you do regular maintenance.

This will go a long way in saving you time and money.

Alkalinity of Water Supply

If the water entering your tank is alkaline, this could be a problem. There could be a problem if the anode rod of your water heater is aluminum.

If it is aluminum and the water in your tank is alkaline, you’re likely to hear a popping sound. High exposure to alkalinity causes a water heater to develop a popping sound.

This happens as the metal connects with the water’s pH level.

How to fix it

The best way to fix such a problem is to change the aluminum anode to a magnesium one. The level of alkalinity for your water supply will not affect it.
