The Series PLT Potable Water Expansion Tanks (Lead Free) are specially designed to effectively absorb the increased volume of water resulting from thermal expansion, ensuring a well-balanced pressure throughout the potable water supply system. With their pre-pressurized steel tank and expansion membrane, these tanks prevent any contact between the water and the air inside, thus eliminating the risk of air loss and guaranteeing a long-lasting and trouble-free operation of the entire system. These tanks are compatible with all types of Direct Fired Hot Water Heaters (gas, oil, or electric) as well as hot water storage tanks. Notably, they are IAPMO listed and ANSI/NSF 61 certified, meeting the highest industry standards. With a maximum pressure rating of 150psi (10 bar), our Series PLT tanks are the reliable solution you need for your potable water expansion needs.

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 2.1 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).
