Sediment buildup causing rumbling and short hot water
Why it happens here
Mineral content in the local water supply settles on the tank bottom and boils under the burner or element. It is worse in homes that have never had the tank flushed.
Our approach
We flush the tank, inspect the anode rod, and check the heating element or burner while we are in there. For hard-water homes we recommend a flush every year to keep the tank efficient.
