Do not use this item for any installation or repair of potable water applications. This product does not comply with the Safe Drinking Water Act, which requires that products meet low-lead standards in order to be used in systems providing water for human consumption (drinking or cooking). This item is for non-potable (non-human consumption) water applications only.
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
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.

Great Purchase!
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!

Has to be better than Amtrol!
Will see if they hold up better than the Amtrol tanks.
They fail in every manner possible. Bladder, pinholes rust out in less than 3 years.

Tank worked and corrected the issue.
Was having a the pressure relief valve leak on my slant fin oil burner furnace… replaced the old tank with this new one and that seemed to resolve the issue. The amtrol only lasted 5 years. Trying watts to see if it's any better.

My pressure relief valve was leaking and I replaced it with a new one continued leaking. I changed the expansion tank that was filled with water and solved my problem. Original tank was 24 years old. Shipping was also very fast from them.

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.
Asked by Les 14 years ago
Add your answer
Verified Reply- PexSupply StaffEven with an expansion tank, you should still have an air eliminator installed on the system.

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
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffPotable 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.

Q: How do determine the correct size of tank for the system?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffThe proper size of an expansion tank for a heating system depends on BTU load. (For water heaters, size is the most important factor).
