Hey everybody,
I am replacing a horizontal six foot section of 1-1/2" copper drain pipe in a wall with 1-1/2" DWV PVC. The holes through the 2x4 studs are 2" and round.
The section of copper I'm replacing was almost level (1/4" in 5 feet), which led to corrosion, which is why I am replacing it. I'll be vertically enlarging the tops of the holes to get get some room to put some slope on the new pipe. I have two questions.
How can I join the more sloped (1/4" per foot) PVC to the almost-level copper? Does anyone ever apply a heat gun or similar to PVC so as to produce a local bend of say 1.2 degrees (about the same as a 1:48 slope). I'm planning on DWV pipe, but I could use schedule 40 on the section being heated and bent. Would that matter?
The house was built in 1968, so I expect the studs are stronger than 2x4's are now. Is there much reason not to enlarge the holes vertically? One of the holes would have to be enlarged about an inch vertically, the others less.
