Hello I am finishing my Basement bar and am installing a new drip tray with drain hole for my Kegorator. I want to use Plastic tubing from my drain hole and connect it to the PVC Piping that is the drain from the upstairs sink. It is only about three feet away. What type of connector should I use to connect the plastic tubing to the PVC pipe, midstream basically? Any help would be appreciated. Thank You.

I live in mid-Michigan and am finishing my basement. I have poured concrete walls and am building 8 foot sections using 2x4 construction. I am stapling a 6 mil plastic vapor barrier on the back of each section that faces the concrete walls. I am leaving about a 1 inch gap between the concrete and wood walls. A number of people have told me to not extend the vapor barrier the entire wall height but to apply it to approximately 12 inches short of the floor in order to allow ventillation. Others have said to apply it over the entire height but then to cut random slits in the vapor barrier with a utility knife. I haven't read anything to confirm these tactics. In fact, I believe I read that in Minnesota anyway, a vapor barrier between the wall and concrete must be installed the complete height from ceiling to floor. No mention of any opening or venting. Can anyone shed any light on the right way to do it? Thanks.
