There’s nothing worse than being constantly aggravated by an annoying sound from your noisy water heater. When a situation like this arises, there are simply steps you can take to resolve the problem. By fixing the problem yourself, you can eliminate an expensive and unnecessary expense.
There are several different sounds that your water heater can make when maintenance or repairs are needed. It’s important to know the difference between them and what they actually mean, so you can get your system up back to working great again. These sounds include:
- Other Weird Sounds
In most electrical water heater tanks, the element is placed in a vertical position. As a result, when the water flows around the element, it can cause vibrations which transform into the sound of humming. How do you fix this problem? The best way to stop the humming is to simply tighten the element. This is an effective way to solve this issue when your water heater is making noise.
Also known as “water hammering”, this hot water heater knocking sound can occur when the water flowing through your pipes is instantly turned off. Whether it be due to the facet, the toilet or the shower, the abrupt stop of water flow causes the pipes to move. Although this movement will more than likely do no harm to your pipes, it can cause damage to your walls overtime. To eliminate this hot water heater knocking sound, you can simply invest in a water hammer arrestor and install it correctly.
Another reason your water heater may make a knocking or even a popping sound could be due to sediment accumulating at the bottom of the tank. Sediment originally comes from the water itself and overtime accumulates at the bottom of your water heater. As a result, this blockage makes your water heater work inefficiently and puts the system at risk of damage. To eliminate the sediment, you will need to flush your water heater tank. For instructions on how to flush your water heater, refer to the section below.
Hissing or Screeching
When your water heater making a hissing noise or a screeching sound, the problem is ultimately caused due to a valve that is not completely opened. As a result, water gets forcefully pushed through a small hole causing your water heater to make a hissing or screeching sound. To resolve this problem, you need to inspect the valves throughout your waterline. Once you open the valve completely, the hissing and/or screeching should not be an issue anymore.
Heat traps and check valves are commonly found in the pipes of many water heaters and are installed to keep water from traveling in the wrong direction. Overtime, these traps and valves can cause tapping or ticking sounds. For most homeowners, this can become quite annoying. To eliminate this pestering sound, you can invest in a dielectric nipple and replace the heat trap with it.
Other Weird Sounds
Tankless water heaters are known for causing their own unique sounds. First, clicking sounds are perfectly normal with tankless water heaters just as they are with regular water heaters. However, with tankless water heaters, the clicking sound is due to the regulation of water by the flow switch. When there’s calcium deposits being deposited as a result of the use of hard water, the tapping sound can become quite loud. By simply investing in a water softener, this problem can be resolved.
Other reasons why your tankless water heater might be making irregular sounds could be due to either a filthy burner fan or irregular gas combustion as a result of a leak. But generally speaking, tankless water heaters in comparison to regular water heaters tend to make less overall noise. For people that are annoyed by these sounds, that’s good news.
