This is a follow-up to my earlier post Fitting a cistern (with frame) into a stud wall (100mm) (follow-up) and also to this post Can i connect waste pipes into soil pipe tee on a horizontal run? I (by @Illuminate).
We've now had the toilet fitted, as described in the earlier post, with the soil pipe running in the floor, with appropriate slope. So that's all great.
However, when I looked at the outside part, the pipe has been fitted horizontally (on a short run), see picture. I would have expected for this to run at an angle, with a Y-shaped fitting rather than a T-shaped fitting Should we complain to the installer? Or is this ok to accept?
Many thanks!
