Airline check valves used with liquid???

[schooleyosis]

Anyone know if liquid can be used with airline check valves? I hooked up my Bubble Magus dosing station and I see that the lines are back siphoning a bit and drawing in a bit of air which will ultimately lead to incorrect dosing amounts.

I do not have airline tubing hooked to it as of right now and I think that is part of the problem. This will be fixed soon as I need to get the proper airline tubing to be used.

I am thinking of putting airline check valves/non return valves inline just to be safe but not sure if you can use them with liquid???

you should be good to go. I have used these with Aqualifter pumps for years.

Good deal, thanks! I plan to put one on the intake side and one on the output side.

HMMM... I'm not sure about that.. you could just try it and see.. but it's going to restrict your pump too.. I don't know if that's good on perstaltic pumps or not..

edit: looks like you got an answer while I was typing :)

I switched the intake lines to air tubing and they seem to be good now. I did try and old non return valve on one to see what happens. Thanks for the insight guys.

I dont think you need one honestly. How long are the lines? You might get more air at first but it should push it all out in a few days.

Intake is maybe 18" tops and the output is 24" tops. It does pull the solution from the floor up to the pumps.

I think the 1/4" water tube just wasn't sealing even with plumbers tape and a zip tie.

It seems to be fine now.
