Description for Watts 0066606

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.

Features:

  • Precharged at 12psi (83 kPa)
  • Rugged flexible butyl diaphragm
  • In-line
  • Compatible with glycol in systems
  • Steel construction


The HydroClaw Expansion Tank Support Bracket provides a safe and reliable option if you prefer to mount your expansion tank. This expansion tank bracket is easy to install and will hold any tank with a diameter of 11" nominal

              I had to change out 2 expansion tanks on 2 boilers both had small drip one more than the other .I first changed out the pressure relief valves but they still leaked, so I knew the 2 expansions tanks failed. I was correct one had about a cup of water on the side of bladder that should have air only. The other tank had completely failed the tank was full of water and heavy as hell! Change both out no more Leaks!

                  We're not sure about glycerin, but it will work with glycol (mixtures up to 50%).

              • Q:

                Experienced increasing noise from pipes. non potable expansion tank 2 years old. 30 psi on gauge. Closed glycol system. Do I need to bleed zones even with expansion tank? Not all zones noisy as far as I can tell. Mostly the one furthest away. I'm very new to hot water system.

                  A:

                  Even with an expansion tank, you should still have an air eliminator installed on the system.

                  A:

                  No, mounting the expansion tank in this manner would not be an issue.

                  A:

                  The tank is pre-charged to 12 psi. Keep in mind that this tank is designed to be used in heating systems (not for potable water).

              • Q:

                We had a plumber replace our expansion tank in our radiant floor heat system a while back and I notice he used a unit labeled for potable water. What is the difference between a potable water tank and one that is for non potable water? Thanks

                  A:

                  Potable water tanks can handle greater pressure (about 150 psi) than non-potable tanks (around 30 psi). We recommend that you either get a new tank or adjust the pressure on the one you have.

                  A:

                  The proper size of an expansion tank for a heating system depends on BTU load. (For water heaters, size is the most important factor).
