The answer to 'why is my water heater clogged' is that a clogged water heater is often caused by a buildup of sediment or mineral deposits inside the tank. This can happen over time as the water heater operates and the minerals in the water settle at the bottom of the tank.
Some common symptoms of a clogged water heater include reduced hot water flow, longer heating times, and strange noises coming from the tank. If left unaddressed, a clogged water heater can lead to decreased efficiency, premature failure, and even water leaks.
