Water heater making noise

Answer: call a plumber.

Popping, rumbling, or banging sounds from your water heater usually mean sediment has built up at the bottom of the tank and is being superheated. Left unchecked, sediment buildup reduces efficiency, increases energy bills, and can accelerate tank corrosion. A plumber can flush the tank, inspect the anode rod, and recommend whether repair or replacement is needed.
