Watts PLT-20 Potable Water Expansion Tank (0067372)

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. IAPMO listed and ANSI/NSF 61 certified. Maximum Pressure: 150psi (10 bar)

5/5 StarsRecommended for all households | I bought this to add to a tankless water heater that was running from the shock in my water system when my washing machine operated. Hammer arrestors did not do the job. My water pressure is 70 lbs I had a 110 lb pressure spike with hammer arrestors daily at a gauge at my water heater. By adding the thermal expansion tank this was reduced to 80 lbs max pressure spike at any time.
Not only does this control thermal expansion. It acts like a large shock absorber for my water system. Protecting equipment that costs much more and is much harder to replace.
Recommended? Yes.
