A.O. Smith PMC-10 Expansion Tank can give water a place to go when thermal expansion occurs. Once the water heating cycle ends, or when any fixture is opened within the system, the impact of thermal expansion will be reduced so expansion tanks adjust its air pressure to match the inlet water pressure. Lastly, the water will drain out of the expansion tank to return into the system.
