Hi,
Just building an extension, including a shower / WC room on the ground floor.
The builder that I had in to build the shell has run a new 110mm soil pipe from the IC in under the joists and up to where the new WC pan will go. However I need to also connect the 32mm and 40mm wastes for the basin and shower. As the shower drain will be at / below floor level it will have to join into the waste under floor level (suspended floor), and I suspect the basin waste will also have to join below floor level as there wont be much of the soil pipe left above the floor before it joins the pan.
I know that making connections under a then to be sealed down floor is not ideal, so whats the best way of making those connections? I was thinking of a strap boss for each, stacked one above the other to prevent cross contamination, but am concerned that the rubber seals will fail over time. I guess the only other option is a boss pipe inserted into the rising soil pipe, at least I could then glue the connections together.
How would you do it?
Many thanks!
Anthony
