Hi, I'm a Gas Engineer currently renovating my new house. I'm not too clued up on running waste, soil stacks etc so looking for a bit of advice
We had an existing 3 1/2 inch waste pipe running out the back. We are extending out to the back now and have cut the pipe down. Stepped it upto 4 inch and ran that along the ground.
Running it up to the bathroom where we hope to tee the basin bath and toilet into it.
This pipe is also used for rainwater/guttering above bathroom.
Plumber says this is ok if we tee off before gutter and leave that section open above gutter. So you would have an opening in the gutter then a 4 inch opening above.
My question is. Is this acceptable for basin, bath, soil and rainwater? He is saying it can be combined as it's an old one pipe system?
Also what is a one pipe waste system?
Thanks
