I am in the final stages of roughing in our basement bathroom and laundry room. I will post some pictures when I am done. This board has been a tremendous help to me....the work would have taken me 3 or 4 times as long to figure out and get right. I have some questions before I finish running all of the drains/vents/supply lines.
1) I have installed the washing machine box in a stud cavity 36" above the floor, next to the washing machine/dryer combo unit. My plan is to run a 2" drain down to a p-trap then over to the next stud bay (where the drain goes to the floor and the vent goes to the ceiling. Is there a height requirement for the p-trap? Does it have to be a certain height above the floor or below the washing machine box?
2) When I run the hot/cold CPVC supply lines to the box, I need to run them through some studs. Do I have to use those plastic insulators at each hole? I got some from a local plumbing supply house and the instructions state to drill a 1 3/8" hole for both the 1/2" and 3/4" insulators. This seems really big to me. Does this sound reasonable? If I drill the holes, do I need to but metal plates on the stud to prevent a screw going into the pipes?
3) When the builder built my house he capped off a 1 1/2" vent pipe which is stubbed out in the joists in the ceiling. It is located about 10 feet away from the bathroom/laundry room. Is there a maximum amount of 90 degree turns that I can make within a certain distance on the vent run? Also, I need to transition from 2" to 1 1/2" at some point? Should I run 2" as far as I can and transition right before connecting to the 1 1/2" pipe stubbed out in the ceiling? Or can I transition to 1 1/2" by the fixtures and run 1 1/2" all the way through the ceiling.
Thanks in advance for your help,
