Popping and crackling from the water heater is sediment flashing to steam. Here is the Redwood City guide.
The cause
A thick sediment layer insulates the burner, and trapped water flashes to steam with a pop.
The flush
A thorough flush removes the sediment and stops the sound.
The deeper issue
Heavy, hardened sediment may need a pro to break it up.
The call
Stop the popping before it shortens the tank's life. Call 888-217-3585 and Redwood City Plumber Connect will match you with a Redwood City pro.
