Is there a nonreturn / check valve for aqualifter?

[Nexenn]

Anyone know of a nonreturn or check valve for liquid dosing? I've seen them sold for air pumps and I have an aqualifter I use for dosing but it back siphons air back into the line once the lifter turns off. I would like to prevent this from happening so I can hook it up to a DIY kalkwasser reactor and air wont come back into the reactor.

Any ideas?

I use the regular plastic one for my auto topoff.. it will work for kalkwasser but you will have to clean it more often because it will eventually clog.

Interesting, my Aqualifter didn't backsiphon...

what do you mean a regular plastic one? like one made for air pumps?

I'm planning on using it for the kalk reactor but i'll place it on the RO/DI in side so it will never be exposed to kalk

i have a aquamedic reactor and it came with one. try searching replacement parts for aquamedic kalk stirer. in theory a aqualifter shouldnt but i had 2 (at different times) that were hooked ot a cpr overflow that decided to blow out both holes. i saved the 2nd one and should make a video out of it.
