Waste Pipe Dimensions

[laurel]

Hello Everyone.

I have a plan for a downstairs bathroom showing one pipe leading from the soil and vent pipe, to a toilet and then onto a basin. Should I try to reduce the size of the pipe after the loo, or try to connect the basin to the 100mm pipe? Or could the drawing be wrong and should I use two seperate pipes for the toilet and basin?

Any advice would be much appreciated

how is the pipe being run, under a floor? surface along a wall?

you will be better off runing a seperate 11/4 waste to the basin connected into the svp, you can get pan connectors that have a 1/14 connection on for a basin which maybe your best soultion. if you go this way then id fit a basin trap with an anti vac valve to avoid problems with the water seal getting pulled away.

the toilet waste is 110mm! you can boss a connection into it (32mm) for a basin, or you can get w/c pan connectors with a built in boss for basins. check out mccalpine products for this
