Nice replacement part, fixed the never-ending drain issue with my RO system.
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.
