I'm installing a temporary drain line for a kitchen sink while a remodel is taking place. The most convenient place for me to tie in the temporary line is into a 2" section of drain line from a bathtub. This particular section, though, is at a 45° slope. Should I use a sanitary tee at this section? A wye? A combo wye and 1/8?
Here's my thought process on why a sanitary tee should be acceptable, but I'm not a plumber nor a Code expert; this is just my engineering two cents.
I have the space to use a wye or a combo, but the other geometry of the area would definitely make it easier to use the sanitary tee. Still, I'd like to do the job properly.
