Assessment
A provider may inspect the tank, connection, support, pressure-reducing valve, backflow device, shutoff, relief discharge, and heater arrangement. The correct size and mounting method depend on the plumbing system and heater.
Find The Cause
Pressure symptoms may come from more than the expansion tank. Replacing the tank without checking the pressure controls or closed-system conditions may leave the original problem unresolved.
