I'm plumbing a lavatory sink. I'm using 1-1/2" piping from a floor above. I have to bypass a floor beam so I went through the wall studs. I drilled through the studs and pitched the pipe 1/4" per foot slope. After passing the location of the beam (about 7' run) I went down through the floor to the level below using a 90 elbow (Not long elbow, the short elbow). I then used another 90 deg. (down about 11 inches in the 2x12 joist bay) going from vertical to horizontal traveling about 4 feet, then another 90 deg through the joist going horizontal to horizontal then connected the pipe to the main drain about 2 feet from the last elbow.
My question is, since it's a lav, would it be permitted to use those 3 90s without being long turn? I already glued the pipes but I guess I can take them out if I have to, the drywall is out now. I wanted to have some opinions about this before I call the plumbing inspector. I'd rather not fail the inspection...
