ok here are my low drains I went to Menard's the other day in search of the 1/4 values and they had them.. the guy there showed me how they work using the same type of tubing I had. My question after leaving the store of course was do I need to cut off the bottom where the plugs are now because the the tube he demonstratedhow they work did not have the fitting that I have on mine right now it was just the tube. I have included a photo to what I am referring to.
