- Checking the expansion tank, fittings, and venting.
- Descaling a tankless unit.
Signs you are overdue
Popping or rumbling noises, cloudy or rusty hot water, less hot water than before, and rising energy bills all point to sediment or wear. Catching these early can prevent a leak or an early replacement.
How often?
Many homeowners flush a tank heater about once a year, and hard-water homes may benefit from checking more often. Ask your provider what fits your unit, its age, and your water.
Common questions
Does flushing really help?
Removing sediment reduces noise, improves efficiency, and helps protect the bottom of the tank from overheating.
What does the anode rod do?
It corrodes in place of the tank steel. Once it is used up, the tank itself can start to rust, so checking it extends heater life.
