Water heater maintenance
Why Is My Water Heater Making a Popping Noise?
Popping is usually sediment at the bottom of the tank. Flushing it once a year typically quiets the noise and extends the heater’s life.
Over time, minerals in hard water settle at the bottom of the tank. Water trapped beneath that layer boils as the burner heats, which causes the popping or rumbling you hear. Left alone, the buildup makes the heater work harder and can shorten its life.
Is a popping water heater dangerous?
Usually not, but it’s a sign the tank needs a flush. If you also notice leaks, a rotten-egg smell or no hot water, call a plumber.
