Anyone know what the minimum fall on a waste run from urinals is? Is it 18mm/m as with other waste pipe branches.
I’m looking at a job and the architect has suggested the following: 10m branch length from ventilated soil stack containing 4 urinals and 3 wash hand basins – basins are at the end of the run.
What would be the best way to ventilate the branch? I was thinking a 50mm AAV at the end of the branch, but cannot remember the height it must be mounted at. Is it 300mm above basin overflow level?
