Okay to mix PVC Pipe (solid & foam core)?
I'm repairing a leak in a drain vent pipe inside a wall (a cabinet installer drilled screws through the wall and into the pipe). The existing pipe is 2 inch "not for pressure" schedule 40 PVC (foam core). I checked the local stores and they only carry 2 inch solid core (pressure) schedule 40 PVC pipe. I need to replace a section about 2 feet long and want to know if its okay to mix the pressure (solid) and not for pressure (foam core) pipe in the same vent line. I'm guessing it wouldn't make any difference, but figured I better check just in case. Also, I'm assuming the pipe and fitting dimensions are all the same? Thanks in advance for any advice.
