Hi all,
I am trying to design a waste system for a new ground floor bathroom with a concrete floor. The property is in rural france so building regs will not really apply as it won't be inspected, but i obviously want to do it right and safely.
The bathroom will have a bath to the right, a sink in the centre and a toilet to the left. To the left of the toilet will be a stud wall behind which will be a large cupboard housing the soil stack and a washing machine.
With regards to the soil stack i envisage a 90 or 92.5 degree access branch to accept the outflow from the toilet. The soil stack will go below this through the concrete floor into a cellar and then through the rear wall via a curved 90 degree access bend and then via an inspection chamber into a septic tank i am having installed.
The vent for the stack will be up through the ceiling into the loft space. Can i terminate it here with an air admittance valve or will i have to take it through the roof to vent?
The bath will have a 40mm waste pipe running just above the floor from it to behind the basin where a 32mm waste will join into it. As this waste run will be more than 5 feet, i intend to run a vent pipe vertically from it between the bath and sink and then horizontally to join the soil vent pipe via a strap on boss.
I am struggling though, as to how to feed this waste from the bath and basin into the soil stack. It will be a bit of a squeeze to fit it to the soil stack via a boss at the same ,level as the toilet waste, so i am thinking to run vertically down into the cellar and accross to join the soil stack below the toilet waste and do the same from the other side for the washing machine waste. I would connect them to the soil stack either with a boss pipe connection or a manifold.
Can i have any feedback on whether this all sounds ok, and if not, where am i going wrong and do you have any better suggestions. Thanks.
