Soil plumbing
The chalet bungalow upstairs bathroom.
Are there likely to be any issues with arranging a short 45 deg. fall in the toilet waste pipe? The current plan is a vertical outfall terminated at a manifold above the soffit. There is insufficient space to get this high enough to accept a full *horizontal* run. Probably 2m level, 45 deg. bend, 800mm and another 45 deg. to the manifold. I will arrange a vented (AAV) stack inboard to be higher than the basin overflow. -- Tim Lamb |

Generally best of you can do it near the source end, but usually ok so long as most of the run is within the recommended falls (typically between 1 in 10 and 1 in 80 for 110mm soil pipe). Its quite common to need a little bit of pipe height adjustment near soil stacks for example. The current plan is a vertical outfall terminated at a manifold above the soffit.

Probably 2m level, 45 deg. bend, 800mm and another 45 deg. to the manifold. Our second toilet exits through the wall, turns 90° and then immediately descends at 45° for about 800mm, before changing again to a normal "horizontal" run. There was no choice, as there was a window half-way down the stairs, between the toilet and the stack, preventing a straight run. It has worked fine for 9 years now, but from the outside, it is quite a bit noisier than the pipe from the other toilet. SteveW |
