How it works
What to expect
Shutoff and safety check
We shut off the water supply to the unit and, for gas or electric models, the fuel or power source, then confirm the work area is safe before touching anything.
Leak source diagnosis
We inspect the tank, valves, fittings, and connections to find exactly where water is escaping, and we distinguish true leaks from harmless condensation.
Repair recommendation
We explain what failed and what the repair involves, and give an honest assessment of whether repair or replacement makes more sense for the condition of your unit.
Repair and part replacement
We replace the failed valve, fitting, connector, or component and reseal connections to proper standards so the fix holds.
Testing and restart
We restore water and power or gas, verify there are no leaks, confirm the TPR valve operates correctly, and check that hot water is flowing properly.
FAQ
Expansion Tank Service questions
What does an expansion tank do?
When water heats, it expands. In a closed plumbing system with a check valve or pressure regulator, that expanded water has nowhere to go, so pressure spikes. The expansion tank's air bladder absorbs the extra volume and keeps pressure stable.
How do I know if my expansion tank has failed?
Common signs are a TPR valve that drips regularly, waterlogged weight when you lift the tank, or a dull thud instead of a hollow ring when you tap it. A technician confirms failure by checking the air charge with a gauge.
Can a bad expansion tank cause other leaks?
Yes. Repeated pressure spikes stress every joint, valve, and fixture in the system, and can push water past the TPR valve continuously. Replacing a failed expansion tank protects the whole plumbing system, not just the water heater.
