Product Details

WATER EXPANSION TANK: The Watts PLT Series 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.
COMPREHENSIVE FEATURES: This field-adjustable steel tank is air pre-charged at 20 psi, has a volume of 14 gallons, and 3/4 inch male inlet connection. The maximum pressure is 150 psi (10 bar).
DURABLE CONSTRUCTION: Designed with a Food and Drug Administration-approved polypropylene liner and Butyl rubber diaphragm, copper-lined steel, and an expansion membrane that prevents air-to-water contact in the tank, ensuring a long system life.
SAVE TIME AND TROUBLE: Our potable water expansion tank also maintains balanced pressure throughout the water supply system by keeping system pressure below the T&P relief valve setting. IAPMO listed and ANSI/NSF 61 certified.
EVERY DROP COUNTS: Water. It's in our name and close to our hearts. Since 1874, Watts Water Technologies has been delivering innovative technologies that make the world's most precious resource safe and accessible. Everything we design is made to keep the Earth's most precious resource safer, cleaner, and more useful for our customers.
