Sediment buildup causing rumbling and slow recovery
Why it happens here
The water supply in the 33971 area runs hard, and minerals settle on the tank bottom as it heats. Over a few years that layer thickens, insulates the burner and forces the tank to work harder for the same hot water.
Our approach
We flush the tank on every repair where we see scale, and we pull the lower element to clean heavy buildup. For corridor homes we recommend a yearly flush, which is far cheaper than replacing a tank early.
