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
TPR Valve Replacement questions
Why is my TPR valve leaking?
A TPR valve usually leaks for one of two reasons: the valve itself has worn out, or it is doing its job and releasing water because temperature or pressure inside the tank is too high. Both situations need a professional diagnosis, because excessive pressure can indicate a failing expansion tank or a faulty thermostat.
Can I just cap off a leaking TPR valve?
No. Capping or plugging a TPR valve removes the tank's protection against dangerous pressure buildup and creates a serious safety hazard. The correct fix is to diagnose the cause and replace the valve or address the underlying pressure problem.
How do I know if the valve is bad or the pressure is too high?
A technician checks this with a pressure gauge and by inspecting the expansion tank and thermostat operation. If system pressure is normal and the valve still drips, the valve itself is the problem. If pressure is elevated, the root cause must be fixed first.
