I'm putting in a new groundfloor bathroom (toilet, shower and basin) in the middle of the house. I'm planning to run in a new 100mm waste pipe from an existing manhole by chopping a trench across one of the bedroom floors.
I have some questions I'm hoping someone can help me with.
1. Is there any minimum depth the waste pipe has to be under the bedroom floor?
2. I think the shower/basin waste and toilet connector would have to discharge into a stub stack in the new bathroom with an air admittance valve. How high does the stub stack have to be?
3. Can the shower/basin waste and toilet waste enter the stub stack at the same level (providing they are not directly opposing)?
