Hi everyone!
I am renovating an old house with shared foul and rainwater drainage. We are installing a wet room downstairs in an old outbuilding with concrete floor, and the builders have excavated the floor and run a new 110mm drain with branches to service toilet, basin and the intention is that the shower will drain into the end horizontally.
While waiting for the plumber, the builder has mentioned that basically to prevent back flow and bad smell from coming up the shower, it will need a particular type of waste. Out of curiosity, I've been looking around about this, and am getting a bit confused. Is he talking about an anti-vac waste, or using a waterless waste as a solution to this. He talked about a valve that opened under the pressure of draining water, but admits that it isn't his area of expertise!
Hopefully the plumber will know what he's talking about, however I'm not curious as to what exactly it is we need, so wondered if anyone could shed any light. Also, are the waterless valves suitable to be buried underneath a wet room floor? I assume the valve he is talking about is serviceable without lifting the floor?
Cheers in advance ,
Gus
