We are finishing our patio in a new build and wanted to install a small outside kitchen with a sink. The closest drain is the drain stack from the second floor. I ran a 2" PVC pipe at 5% slope and I'm at a point where I need to drill into my foundation. My friend who is a licensed plumber was supposed to come by and assist but couldn't make it because of some emergency calls.
At this point, I have 2 grey areas:
I am aware that having a lot of 90s is not recommended but this sink won't be used often so I can try and dig a bit more and install 45s(in red) instead of 90s.
What would be the easiest way to cut my 2" PVC into the 4" drain?
