Water heater maintenance is the best way to extend the appliance’s lifespan. Plumbers perform maintenance to ensure you have an ample supply of hot water. They also assess the water heaters for common problems. However, as water heaters age, you may notice them making odd noises. Continue reading to learn what these water heater noises mean and how plumbers fix them.
Popping and Rumbling Noises
A popping or rumbling noise could indicate a high level of sediment in the tank. The water becomes trapped under the sediment. When the water boils, it will create a popping or rumbling noise. To fix this problem, a plumber will drain the water and flush out all the sediment.
Banging and Knocking Noises
Banging and knocking sounds occur when a valve either stops water from moving, changes its direction or shuts itself off. Pressure will build up inside the pipes, resulting in this noise.
The plumber will fix the problem by checking the water pressure with a gauge. A pressure reading over 80 psi means the water heater needs water hammer arrestors.
Ticking and Clicking Noises
A ticking or clicking noise means that metal pipes or parts are expanding or contracting inside the tank. This happens when the water heater heats water and then cools down. The plumber can correct this issue by tightening any loose connections or parts that are rattling.
Hissing and Sizzling Noises
Localized boiling can cause a hissing or sizzling sound. This occurs when sediment builds up on the lower heating element in an electric water heater. However, in a gas water heater, this noise could indicate that condensation has started to drip onto a burner. The plumber will flush sediment from the tank and check for a possible gas leak.
Humming and Buzzing Noises
A humming or buzzing noise is only a major problem if it is excessively loud. If this is happening, the heating element may be hitting the tank. The plumber can correct this by securing the element back into place.
Whistling and Screeching Noises
Whistling and screeching sounds indicate a problem with a valve. It’s loose or partially closed, and the water is forced through the tiny opening. The plumber can check the valves to ensure they aren’t closed or ajar. If the valve is faulty, they can replace it.
Maintaining your water heater helps you avoid costly repairs. Plumbers can perform these services to address water pressure issues, damaged parts and sediment buildup.
