Description

An expansion tank. Model ST-30V. 14 gallon. Takes up the volume change as the system water heats, so pressure does not climb until the relief valve lifts. Rated for potable water service. Set the tank pre-charge to match system fill pressure — a tank charged wrong is a tank doing nothing.
