Installing a new vanity, and like idiots, we forgot to account for a floating cabinet when plumbing hookups went in, so the drain outlets have about 3-4 inches clearance below, but there’s plenty of space otherwise. The plan is actually to try some waterless valve traps anyway, but if we don’t like them, or there’s some future inspection issue, can it simply be sloped up at a 1/4 -1/2 in grade? Maybe also with some bends to save space?
My plumber comes to install in a few days, and I’d like to know how much of an idiot he’ll call me
You need to either open up the wall in that bathroom or on the other side and rough the sanitary line in at the proper height. Don’t fuck around and try to reinvent the wheel when it comes to plumbing, it never works. This shit was figured out long before we got on earth by far more intelligent people than we will ever be
I don’t think sloping a pipe downwards at a 2% grade is exactly reinventing the wheel, but tearing the other side open isn’t out of the question.
If is is not carrying solids i agree but the problem would be going beyond the acceptable tollerances of the mechanical joints and glue joints of the fittings.
I have seen too many times something that is forced cause major damage. The cabinetry looks nice and rather than take the time while it is not at the point of no return to make it correct would be foolish. Sometimes you need to drop back and punt 🤷♂️
Oh ok. I was going off the assumption there was a joint meant for this, or something with some give, or I dunno maybe a heat gun? I wasn’t thinking it would just be forced.
And no solids, it’s just a master bathroom sink with no kids, so mostly soap and germs.
