advice - adding/modifying soil pipes in bungalow

[grahaml]

Thanks, while I am here - a couple of related questions;

1. what would be the best way to connect the waste from the shower and whb? The existing bathroom ones go into 110mm branches with an adapter - is that OK or are there neater options?

2. Would I need a vent for the soil pipe in the ensuite - I'm thinking I would and would just do the same as in the existing bathroom - but into the loft space with an air admittance valve. Would that need to be 110mm or could I use smaller?

Thanks,
Graham

The addition of a new bathroom and the modification of sewage disposal are notifiable to building control for certification or need to be carried out by a person registered as competent.

Hi there I think the most difficult thing here may be getting your length of pipe down under the floor you may have to take it down in sections....brum

Many thanks.
I hadn't thought about the issue of getting a length of pip under the floor. However access isn't too bad and the length I need isn't that long anyway - maybe less than 1m and the depth to the ground under the floor is about 600mm.

I'm checking the Building Control issue again with architect but I was advised at the outset from him that all was ok. I'm in Scotland and I know the regs are different from England. We will soon see though.

Any advice on earlier questions ?

Hi again I got your thread mixed up with another one where the wc was a distance away if your only talking a couple of metres existing stack will suffice but a durgo wouldn't hurt to fit one plastic boss caps with reducing adaptors are best for shower and basin also durgo could go down to two inch pipework ....brum
