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

    This is clever as hell. Don’t know if it’ll pass code though if you’re already permitted. I’m sure it’ll work just fine, but how long is unknown since it’s new(er) technology.

    If you have enough space, it looks like this one might be a better alternative since you can open the front to clean the membrane out (which you will need to do to keep it sealed over time).

        Well, we’ll see, it sounds like normal trap won’t be a problem. They are supposedly pretty not uncommon in the UK, for space reasons, and people seem to like them. It’s daily, but light use, and unoccupied in the summer. So unless it fails from pure friction and wear, I don’t see how it could really be an issue, but yeah, things do have a tendency to be made like cheap lowest bidder garbage, so…

          Well, the house is unoccupied during the very hot Arizona summers, and these never lose their seal when clean. And also, it’s the master bathroom in a detached guest house, so it’s mainly just used in the morning and night, with basically nothing more than soap and toothpaste. No little kids pouring paint and whatnot down the drains.

          Also, the house has no basement and very little storage, so the more space, the better.
