iSpring AAS2 Reverse Osmosis Water Filter Automatic Shut Off Valve Quick Connect, Whilte

This stopped my never-ending drain issue with my iSpring RO System I got back in 2013. When you refill your tank with pressure, this can make the drain problem show up a little easier. You can check if it's the ASO valve vs the check valve by turning off the tank valve, but leave the inlet valve open (that comes from your house water supply). If it continues to drain then the ASO valve could be bad.. If you do the opposite (turn on tank valve, off inlet water supply) and it stops draining then it's most likely the ASO valve. Some tips for installation: Make sure you buy extra RO tubing with this so you can put new tubing on at the same time, especially if your old ASO valve has screw on fittings like mine did. Push the tubes in pretty forcefully into the quick connect fittings, if you don't push past the rubber ring inside, it will leak at that fitting. You can take the little plastic lip piece out to see where the rubber ring is to get an idea of what you will need to push past. There are some good youtube videos on how to install these correctly if you are still stuck. Before you put the RO system back, leave it out for 10-15 minutes with everything turned on to make sure nothing leaks. If any of the quick connects are leaking, see the note above about pushing it past the rubber ring. You can use petroleum jelly if it's being really stubborn.

Here you go, lessons I learned the hard way (my ASO valve would not operate correctly): 1) Make SURE you understand the IN & OUT ports and hook up the lines correctly to ASO valve. 2) Use ONLY hard lines to interconnect (dont use clear lines from home depot, they are too soft and valve wont shutoff correctly). 3) Keep all hard tube lengths to ASO valve as short as possible. 4) On all connections make sure the tubes push all the way down 5) On all post carbon filters, post filters, etc...dont plug tubing directly into these filters, always use a push in connector first then push your tube into those connectors. I did all above and fixed my ASO valve RO system operation.

We all expect products we invest in to do the job, and iSpring RO systems will not disappoint - but what sets this company apart is the terrific technical support. Today, Nick simply and easily helped me troubleshoot and remedy a problem - honestly, so nice to know a company has talent like that and the desire to provide such great service.

The one that came with the water filter system broke only after 5 months. I got a replacement and that one lasted longer, for a year and 8 months. We'll see how long the new one will last. As for how the device functions and the installation with the quick connect, it is great. Durability not as good.

My RO system was not turning off and I could hear the water trickling all day long. After some research I ordered this part. Before replacing, turn the valve off on the water supply and the RO tank. It took about 2 minutes to replace and now my RO systems shuts off when the tank is full.

It is one of the most important parts in the reverse osmosis system. The company's customer support is crucial. Thank you Nick, Sean and Michelle.

I spoke with John at iSpring in Cummings, GA and he sent the replacement parts ASAP. They were very helpful!

This was easy to install, and when I got the lines mixed up Nick was there to the rescue 10/10 would buy again.

Worked as promised. Thanks

Good

Excellent! Fast shipping! It stops the RO waste water flows when water tank valve is in shut-off position AND it stops the waste water when the tank is full! All good!

best buy, good quality

Worked great
