Where should the soil pipe enter through the slab?

[pobourne]

I'm building a new house and want to know is there a standard location\ distance from walls that the soil pipe should come up. The pipe will take a WC on the GF and then stack up to the 1st floor to take the bathroom above and then up to vent tile so he'll need a couple of T connectors which usually have a boss adaptor on 3 sides. I'd like the boxing to be as narrow as possible but without snookering the plumber on his first fix and they can't be adjusted afterwards due to a gas membrance secured around the pipe before the pour of the floor.

I've attached a GF plan and the SVP's are shown.

Thanks in advance

You need to think what your having on the walls eg tiles plasterboard etc

normally a clip off the wall

Thanks for that. I've allowed for the plasterboard +25mm for the collars of the fittings and a bit of wiggle room. Sound about right?

Yes I normally allow 105mm to the centre off finished wall eg tiles plaster etc
