Watts 0067371 PLT-12 4.5 Gallon Tank Potable Water Expansion Tank: Unleash the Power of Thermal Expansion and Balanced Pressure!

This potable water expansion tank is used on gas, oil, or electric, direct-fired, residential water heater and hot water storage tank applications to absorb the increased volume of water created by thermal expansion. It also maintains balanced pressure throughout the water supply system by keeping system pressure below the T&P relief valve setting. This field-adjustable steel tank is air pre-charged at 20 psi, volume 4.5 gallons, designed with an FDA-approved polypropylene liner and Butyl rubber diaphragm, copper-lined steel, and 3/4 inch male inlet connection. An expansion membrane prevents air-to-water contact in the tank ensuring a long system life. IAPMO listed and ANSI/NSF 61 certified. The maximum pressure is 150 psi (10 bar).

Series PLT Potable Water Expansion Tanks are designed to absorb the increased volume of water created by thermal expansion and to maintain balanced pressure throughout the potable water supply system. Series PLT tanks feature a pre-pressurized steel tank with an expansion membrane that prevents contact of the water with the air in the tank. This prevents loss of air to the water and ensures long and trouble-free life for the system. These tanks may be used with all types of Direct Fired Hot Water Heaters (gas, oil or electric) and hot water storage tanks.
