Urgent professional plumbing problem!
I have searched online, and of course no workers at the hardware store know the answer - I'm hoping someone here will.
Also, I called another plumber yesterday, just in case I was stood up today (had a baaaad feeling). Can't get to it until "at least" Thursday.
It's a bit complicated, but I'll do my best to explain it clearly.
House is being rehabbed, on a concrete slab. Stud walls now, with access to the end of the tub.
I need the new tub installed - now.
Drywall is being delivered Tuesday and installed Wednesday.
Had a plumber scheduled to install the tub, drain, & valve today.
He's ghosted me the last couple days, when I tried to contact him to set a time - and has stood me up today.
So, if I don't get the tub in soon, the drywall guys (and everything after them) will be delayed & PO'd.
SO... I'm looking at possibly needing to do it myself, but I'm not familiar with it / done it much.
I've reviewed installation instructions online, and it seems very doable, when the p-trap is already correctly located.
BUT - here's the problem.
The 1 1/2" drain pipe comes straight up out of the ground, above where it tees into the main, horizontal drain. It's new - was just roughed in.
The center of this pipe is c. 2" to the side and 2" to the rear (further from the wall) than where the tailpiece of the tub drain/overflow pipe will come down.
There is no p-trap installed yet, and the p-trap will normally empty into a horizontal pipe.
So, it seems to me like there is not enough room to (easily) attach a horizontal pipe from the vertical drain to the p-trap, and anything close to an s-trap would create a sewer odor problem. It's too close to create an S drain, anyway.
I could do a 90 directed to further away from the wall, with a straight piece of pipe, then loop it back with another straight piece of pipe (all below grade) to a p-trap that would (hopefully) fall pretty close to where it needs to be, . And use compression-fitted (rather than glued) drain/overflow assembly for just a little flex.
BUT - that would create extra bends & I don't want to encourage clogs or make it more difficult to clear them. And it would take space that I don't really have - would need to cut away some of my newly-poured floor.
