Auto shut off valve

[mark]

See Aquasafe back in business, wondering if they'll allow pick up now?

One thing though, my ro/di won't shut off either, I've taken apart and cleaned the ASOV to no joy, but reading that a faulty check valve might also be a cause.

Ya my cleaning attempts also failed. Where is the check valve located? I have an auquasafe unit and was unaware of a check valve

Mine died two days ago I took the check valve off and rehooked everything up with the tubes so the membrane doesn't go dry til we can afford a new valve.

Edit ok so I guess the membrane wouldn't be dry but it would be sitting there in non-moving water stagnating and likely getting ruined because of that.

Found the check valve and will clean it tonight

Thanks all. I
l'll post my efforts tonight

pardon my ignorance, but what exactly does a check valve do? I don't think my aquasafe unit has one.

never mind, I put it together. The hamster is lazy on the wheel today

It just stops the back flow of water. It should be part of 1 of the elbows of the exit of the RO membrain

Scroll down through this link to show you where it should be. I'm checking mine after work

I don't fully understand maybe. If a check valve is not working it lets the water seep out of the membrane canister letting it sit dry?

Sorry, I meant the thingie marked "ASOV" on the Melev site above (auto shut off valve). Mine is attached to the end of where the three canisters go into the membrane and then goes to the DI. No water was going through it, so no new water was being made, which means my whole unit was sitting there stagnating for a day.
I took mine apart and the rubber inside looks degraded. I rinsed it all under hot water and put it back together and water is flowing again through the "thing". I need to buy a new one because I don't think that'll work for long.

Do we even need this thing or what? I'm not too sure what use it is....

In my experience these things are cheap and break all the time. Taking them apart has never gotten them working again for me. This time around I've chosen to remove it entirely and manually fill my reservoir every week or so after a water change.

You need that ASOV Otherwise, your reservoir of good RO water would be full, and not flowing, but water would still flow to the drain
