How to Fix Popping Noise in Water Heater
If you have been living with a noisy water heater for a long time, it is time to do something about it. In this section, we’ll focus on how to fix the popping noise in your water heater.
Check the Heating Element
The heating element in your water heater could be the reason for the popping noise. When the element heats up, it causes the water to expand, leading to the popping sound. To fix this, turn off your water heater and wait for it to cool down. Open the panel on your water heater, remove the heating element and inspect it for damage. If the element is faulty or damaged, replace it with a new one.
Insulate the Pipes
Another reason for the popping noise in your water heater could be due to the expansion and contraction of your plumbing pipes. You can insulate your pipes to prevent the popping sound. Buy foam pipe insulation from a local hardware store and wrap it around the pipes, ensuring that it covers the entire length. The insulation will reduce the sound as water flows through the pipes.
Lower the Temperature
If your water heater’s temperature is set too high, the water will boil and cause popping noises. To fix this, turn down the thermostat on your water heater. The recommended temperature is 120 degrees Fahrenheit.
Drain the Water Heater
Sediment buildup in your water heater can cause popping noises. Over time, minerals, dirt, and debris can accumulate at the bottom of the tank, causing the water to boil. To fix this, drain and flush your water heater. Turn off the power or gas to the heater first, then connect a hose to the drainage valve. Open the valve and let the water drain out. Close the valve and refill the tank before turning on the power or gas.
Install a Water Hammer Arrestor
If all else fails, you might want to consider installing a water hammer arrestor. A water hammer arrestor is a device that absorbs the shock from water hitting a closed valve, preventing the pipes from shaking and banging that causes the popping noise.
In conclusion, the popping noise in your water heater can be a nuisance. However, by following the steps above, you can fix the issue and enjoy a quiet and efficient water heater.

Tankless Water Heater Sounds Like a Jet Engine
If you’ve ever heard the sound of a jet engine taking off, a tankless water heater making the same noise can be concerning. Although it’s unlikely to be as loud as a jet engine, a tankless water heater can produce a similar whistling, roaring, or hissing sound. Fortunately, the noise is not a sign of a malfunctioning tankless water heater, but rather a common occurrence that comes with owning one.
Why Does a Tankless Water Heater Make Jet Engine Sounds
The reason behind the sound a tankless water heater makes is nearly identical to the sound of a jet engine. As water flows through the system, it creates steam by heating pipes that are in a near-vacuum. This process is known as ‘cavitation’ and is responsible for the sound. While most tankless water heaters include sound-absorbing materials like rubber to reduce the noise, they may still produce audible sounds.
Is It Dangerous
The noise is typically not a sign of danger. However, it’s important to keep in mind that the sound could indicate a problem if it’s coming from the heater’s electrical connections. If you suspect this is the issue, shut off your tankless water heater and contact a qualified technician.
How to Reduce Jet Engine Sounds
If the sound is still problematic, some potential solutions may help reduce the noise. Start by adding insulation around the pipes to mitigate vibration and noise. Similarly, make sure the water pressure in the house is not too high. If the water pressure is too high, it can contribute to the cavitation noise, and you can reduce the pressure by adjusting the pressure reducing valve. Lastly, consider having a professional installer come to the house and evaluate if there is a fault with the unit that could be causing the noise.
In conclusion, jet engine sounds coming from your tankless water heater are typically not an alarm bell but more of a quirky noise that comes with owning this type of system. However, if you suspect a problem, don’t hesitate to get it checked out by a qualified technician. With proper installation and maintenance, your tankless water heater can provide ample hot water without the inconvenience of hearing an aircraft passing overhead.
How to Quiet Your Tankless Water Heater
