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
Really? It seemed to be against code in most places near me, along with S traps. I don’t live in the UK.
That’s crazy. We have quite strict codes when it vomes to plumbing and we use them for a long time.
@[email protected] you are correct. After researching this for just 5 minutes, I was definitely mis-informed. It’s shocking that so many brands sell very expensive versions of this like https://www.kohler.com/en/products/bathroom-accessories/shop-bathroom-accessories/bottle-trap-1-1-4-x-1-1-4-9033.
No worries, I went through the exact same process a couple weeks ago.
It seems theyre legal in some parts, but there should definitely be a disclaimer, or cigarette style warning included. “Bottle traps may cause inspection failure.”
