Series ETX non-potable water expansion tanks are for use in commercial and residential closed loop hydronic heating system piping to control the thermal expansion of hot water and maintain system pressure below the relief setting of the relief valve. The pre-pressurized steel tank features a durable expansion membrane that prevents contact of the water with the air in the tank. This rugged diaphragm minimizes loss of the air change and ensures long and trouble-free life for the system. Model ETX mounts to supply piping.

Comments about Watts ETX-60, 6.0 Gallon Non-Potable Water Expansion Tank:
I bought this because my 4.4 gallon tank either failed or became too small as I expanded my system. This was a perfect replacement, requiring no alterations to the system. It solved the issue of the pressure relief valve opening every time the furnace got hot. If it lasts for 15 years like the other one did, I'll be happy.
