Why Is My Water Heater Making Noises?
If you’ve ever heard a strange noise coming from your water heater, you know this can be a quick cause of concern. If left unchecked, this underlying issue can lead to costly repairs or even a complete replacement of your system. Thankfully, our experienced team at Meetze Plumbing knows how to help! Read on to learn about the different types of water heater noises, what they mean, and how seasonal maintenance is essential for keeping your water heater running smoothly and safely.
Loud Knocking Noises
If your water heater is making a loud knocking noise, it’s usually due to sediment buildup. Sediment buildup occurs when minerals in the water settle at the bottom of the tank. When the water heater heats the water, it causes the sediment to harden and produce a knock. Troubleshoot this problem by draining your water heater and then turning off the power or gas supply and the cold water supply valve. After the tank has been drained, open the hot water faucet, which will help flush any remaining sediment out of the tank. It’s best to hire a professional plumber to flush your water heater tank to ensure it’s done correctly.
Whistling or Screeching Noises
Is your water heater making a whistling or screeching noise? High water pressure may be to blame. High water pressure causes water to move too quickly through the pipes, leading to vibrations and noise. To fix this issue, check the pressure regulator. The regulator is usually located where the water enters your home. Adjust the pressure valve until the pressure is between 50 and 60 psi (pounds per square inch).
Rumbling or Popping Noises
Rumbling or popping noises can indicate the water inside your tank is boiling. When water boils, steam builds up and tries to escape, producing a popping noise. Drain the tank and clean it thoroughly. If the problem continues, replace the heating element or thermostat.
Hissing or Sizzling Noise
Hissing or sizzling noises are usually a sign of a leak. A leak can cause water to drip onto the heating element, creating a hissing sound. Check the pressure release valve and the connections to make sure there are no leaks. If you find a leak, turn off the power or gas supply, and call a professional plumber.
Humming or Buzzing Noise
If your water heater is making a humming or buzzing noise, check your heating element. The heating element heats the water inside the tank. If it’s not functioning properly, a humming or buzzing noise can occur. Turn off the power or gas supply and replace the heating element.
