Hello all,
New to this forum so I will try especially hard to be succinct. It would be so helpful to have some feedback and see if I'm anywhere close to a solution or still miles off the mark.
I am completely refurbishing a bungalow I have bought, all internal walls down, new rooms in different positions. The floor is an uninsulated groundbearing concrete slab (approx 100-150mm). I plan to run a new soil pipe under the floor, with the highest level of the 'horizontal' pipe being no higher than the underside of the slab. This new soil pipe will follow the line of the existing (removed) soil pipe but at a lower level. Please see the attached sketch, this seems like the simplest way of doing it but I am eager to get some feedback as it will almost certainly need some changes. I have two questions in particular, but welcome all constructive thoughts.
1) Being on the ground floor, without any vertical drop to help speed waste along, do I need a steeper gradient? I have currently done my workings based on 1:80, which I understood to be correct by the building regs based on anticipated peak flow and pipe size (110mm).
2) Downstream from the WC I need to connect a washbasin, shower, kitchen sink/dishwasher. My natural instinct was to use a strap/boss/adaptor (each solvent weld), however I wanted to be sure that this is suitable for a) a horizontal run, and b) underground use.
Any comments on the above and one the design in general would be much appreciated 🙂
Kind regards,
Chris
