Expansion Tank Installation in Mililani, HI

Closed plumbing systems build pressure when water heats and expands. Melvin's Water Heater Service installs a pre charged expansion tank sized to the water heater gallon capacity. The tank bladder absorbs volume change and keeps pressure below one hundred psi. A pressure reducing valve on the main line maintains system balance. One paragraph states the typical pre charge of forty psi for residential units.
Mounting the tank vertically on the cold inlet line avoids stress on solder joints. Call (833) 774-1697.
