How does it work?
iSpring pre-pressurized tanks are perfect for use in under-sink water storage with your reverse osmosis system. The RO process is on the slower side, so a pressurized storage tank is typically required to supply water from the system on demand. Your RO system will fill the tank to capacity, and when you open your RO water dispenser, the water is sent out by the tank's pressurized air bladder.
- All tanks have a maximum working pressure of 100 psi.
- iSpring Pre-pressurized tanks are tested by independent third party against NSF/ANSI standard (61 for Drinking Water System Components) for material safety and structural integrity requirements, 2018
-
iSpring tanks have a special surface treatment on the metal body that prevents rust and dent.
-
All of our metal tanks pass pressure tests before we ship them out to customers.
-
Unlike traditional plastic, stainless steel that does not break or strip easily is used in our tank valve thread and pressure check valve.
-
Inside all iSpring tanks, a durable butyl diaphragm with post-cure procedures provides a tasteless and odorless water chamber.

Had low pressure, old tank would not maintain pressure. Put the new tank on and it's running great AGAIN!

I contacted customer service to dispose of a tank that had little pressure. Robert gave me instructions on how to dispose, but then also gave me some steps to try to see if we could restore the pressure. It worked!
Thank you, Robert, for your help!

bought a replacement storage tank as the floe out of our ispring 6 stage ro filter was getting too short. The old tank was 7 years old and the air bladder must have given up the fight. Now with the new tank which was easy to replace we are running like new with full volume..

Lots of water again with this new tank!

I've owned a couple of iSpring systems and have always been satisfied. I recently reached out to Sean in customer service about a problem with the RO water pressure. After talking to Sean (who was great BTW) it was determined I had a dead tank. He kindly offered to send me a new tank - even though I was past the normal warranty time frame. Excellent customer service!!!! Many thanks!!!

Just as described and works perfectly. Should have replaced the old tank with leaking bladder much sooner - it's great to have the full volume of water again!

I needed a warranty replacement tank. Sean made the process quick and easy. Very satisfied with my iSpring purchase and will come back when I need something else for my RO system.

How do I drain tank for maintenance?
