number of toilets on a horizontal pipe

[malc]

hi all, just about to start a job converting old church building to nursery school
architects plan shows 4 toilets (low height) in a row connected to stack at the end, customer wants 5, will this work, as can`t get any fall in pipe as all 5 toilets need to be same height ?
can`t get much insight reading the regs.

cheers.

I doubt very much you will achieve that with above ground drainage its bad enough on full size toilet pans let alone nursery low pans I think the floor will need taking up. Kop

If it’s kids height you will do 2 maximum 3 if you can do a bit of digging round the connection
