Product Overview

Thermal Expansion Tanks are designed for pressure control in potable water systems. The tank uses compressed air to maintain system pressures by accepting and expelling the changing volume of water as it heats and cools. It prevents the water heater pressure relief valve from opening, saves energy and eliminates a potential safety hazard. It is commonly installed in a domestic hot water system that contains a backflow preventer, a check valve or a pressure reducing valve. Measures: 11 in. L x 7.9 in. W x 11 in. H with 2.1 Gal. tank size, 6 lbs. weight and 3/4 in. connection size (NPT).

Ordered this on line for store delivery. Was there earlier than originally promised, pick up was very quick and easy. Installation was a snap as the old unit was not too hard to access and it came off smoothly. Time will tell if this unit lasts as expected. Saved about $150 vs. a plumber!
