Hi,
I have worked out that I can replace a saniflow in an extension, with proper drainage - there's enough fall to the existing manhole based on 1:25 fall - total length is about 17 metres. Previous owner obviously took the easy route.
Thing is, I want to plumb two bathrooms to it. The first section from bathroom 1 to bathroom 2 is about 2.5 metres. I can get the required fall and sink it into floor slab - messy but doable. Each bathroom has WC, shower and basin.
Then there's a drop of about 15cm to the outside ground level, and the next 15 metres or so can have the same 1:25 fall.
All the advice and documents I've read talk about vertical soil stacks and the recommendations around those for additional fittings etc. Are there any things I need to look out for when most of the run will be horizontal? I am assuming that putting some kind of access about half way along is advisable.
Any advice gladly received.
Matt
