Hello mfk. Thanks for reading my post. I currently have a small question. I made a PVC over flow I used air line into the top "u" got a prime/ one way valve my question is can I install a few of these (3-4) ? I figure if I have more than one just incase one fails It will have backup. Also I siliconed the hell out of the tube into the PVC I tested it many times it doesn't leak at all!
