   This product arrived on time and came with clear instructions. I replaced it in a few minutes and connected it the same way as my old one. No more running water in the drain.

   Works great. Had a little issue with figuring out what holes were the control holes for the shut off lines. The blue side is the waste water side and the white side is the fresh water side.

   I bought 2 of these valves after reading these reviews saying these are all defective. Go figure I replaced the filters instead and the system is happy again. I also purchased a new tank, I will plumb this in for extra capacity. Some days it’s just simple folks.

   My RO system started running constantly after a few years and I noticed an increase in my water bill. This part installed in 5 minutes and fixed the problem.

   Took 5 minutes to change out no tools needed. System is no longer continuously running into drain with faucet off. Happy OEM parts are so cheap and available through apecwateroutlet.com prime.

   The automatic shut off valve didn’t come with clear instructions so I made this easy diagram to explain how it should be installed. I am using this with a Premier Watts RO filter and it is working great but the instructions were not helpful for me because my hoses are different colors and the system is a little bit different. I was having trouble with my system and it turns out I had installed the automatic shutoff valve upside down. I put the blue hose in the blue hole but that was wrong for my system. Follow this diagram if your faucet isn’t giving you any water or if your valve appears to be DOA.

   There are many choices for this item. This one works much better than the previous replacement. Good flow, good tank refill control, looks solid and not cheaply made.

    Great product. It fixed the trickling problem I was having with my existing RO system. My existing system is a Watts RO water filter system. My two-year-old Watts RO unit never stopped trickling water into my sink drain. It just kept running and running and the sound was annoying, not to mention that it was wasting water. So I first changed the filters (not the membrane), but that didn’t fix the issue. So I decided to change the auto shut off valve before spending a lot more money on the RO membrane. Lucky for me, the shut off valve fixed the issue. The water now stops trickling only a couple minutes after I fill a glass. However….this valve didn’t fix my capacity issue. When my RO unit was new I could fill a 1.5 liter bottle in one shot, then it got to the point where I could barely fill an 8oz glass before the water ran out. I fixed the capacity issue by adding a little air pressure to my RO tank using a bike pump.
