Hi all,
I'm converting a pantry into a downstairs loo/shower room.
The sewer runs along side the wall where the wc pipe will come out and into a stub stack. I have excavated a hole to the sewer pipe, which is below the foundations and 16.5 inches (centre line) from the wall - see image. The 7" sewer pipe is currently laid on earth. I will be putting a 160mm, 45 degree T into the 7" sewer pipe which reduces to 110mm" on the t itself. I have three questions:
1. Do I have to have a flat invert bend that connects to the side of the sewer line or can I position the t so that I run the 110mm stack at an angle so that I don't have to dig too close to the foundations.
2. Once I've made the new connection do I fill the trench with pea gravel or concrete up to the bottom of the foundations?
3. Does the stub stack need a rodding point, or can I simply go through the top of the stub stack if necessary?
Any advice gratefully received.
