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

    There’s about 3 inches between the outlet and the bottom of these 24"x24" square cabinets.

    More like 4" on the left side, but the right one is a bit lower.

      Is that fresh rough in pipe? Fire the plumber or have them come back and open the walls to move those up. Or move the cabinets down tops seem custom? No ID why they are set that high above other bases? Nor why they shouldnt be moved down. You storing ferret beds under there or something?

      The tops are not in. I wouldn’t go further without fixing correctly. No amount if pitch on a trap arm is gonna fix that

        Nah, it’s just a design choice, it’s for my parents and they didnt want a big solid rectangle. Anyways the counter tops are in now, so that’s not changing. Personally, I would have kept the tops all level, but it does look nice and architectural all finished.

        And we do all know better, and he confirmed placement with us, so it’s our fault, really, just a very stupid oversight.

          Then try to offset them in the cabinet with street vent elbows and spin the trap sideways to leave room for the arms reduce to 1-1/4" trap to save some space

            Thanks for the advice! It won’t be necessary anyway, with the traps going in, but I will save this and suggest it if it gets changed to normal p trap later.
