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 for non daily use in an RV set up. This will fail and your sinks will be constantly slow/ smell like shit.
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…
