Hydronix PA-E RO-122 Small Reverse Osmosis Water Storage Pressure

This was a replacement tank for an existing installation. The previous tank was a 5-gallon and took up an excessive amount of room under the sink.I have never done this type of installation before, but it was easy enough: 1) turn water to RO system off; 2) turn old tank off (there should be a valve on the old tank for this; if not, get a bucket and lots of towels ready); 3) disconnect (see below) the hose going to old tank (you can do this at either end, but there will be some leakage; also if you do not have a open/close valve on the old tank, disconnect the hose at the non-tank end and stick it into your bucket as quickly as you can); 4) remove old tank, take outside, re-open valve, admire the fountain; 5) unless you bought a new one, unscrew valve from old tank; 6) put a couple of turns of Teflon tape around the new tank stem; 7) screw valve onto new tank, leaving valve in open position; 8) put new tank into place; 9) reconnect pipe; 10) turn water back on and check for leaks. Leave it overnight to come up to pressure (water stream will be feeble until this happens).A note on dis- and re-connecting hoses: my installation used push-on connectors and I found that pushing in the little ring surrounding the hose and then pulling on the hose was the easiest way to get them disconnected. I really needed a third hand or a pair of small pliers. Also, when re-connecting the hose, make sure they are pushed in the whole way!

Had to replace one w a damaged bladder. Works perfectly

Bladder in our original tank failed. Contacted Whirlpool and they "suggested" that although we could purchase a replacement tank through them, it would be more cost efficient if we purchased a completely new system. It would come with filters that we wouldn't need right now, but could keep for later.I was hesitant to shell out another $300 for a complete unit when all we needed was a new tank and figured for the price, I'd give this one a try.The only snag, was that the valve fitting on top did not fit directly to the line connection of the Whirlpool system.No problem - - - remove the adapter fitting, and connect.Fits, works and what a cost savings.

Easy install and works good.

Liked, the whole water tank looks good quality & received 2024 new tank.thank you!

Fit perfectly where the other was and so far so good. It’s been in about 2-3 months now with no issues.

My previous tank quit pressurizing so I bought this as a replacement quite a while ago. It's worked just fine. I've had no issues.

My old one simply stopped putting out water. The pa-e 122 replacement works perfectly.
