Help with waste pipe runs

[adam81]

The run that is horizontal (so to speak) is only about 30cms, with the vertical above it. Doing this though would mean a 90 degree bend in 32mm waste before the horizontal (so to speak). As you say an ideal place for hair build up.

I found this fitting, so push fit into the end of the orange pipe, http://www.travisperkins.co.uk/p/osmasoil-black-solvent-weld-system-boss-adaptor-32mm/818037/3961006

This is obviously above ground stuff really though. In searching for all the other bits I didn't find anything that could be put under the floor, which is why I went for the inital suggestion of finishing just below floor level.

If only the missus would agree to a pedestal sink this would save so much hassle..

No harm in using above ground stuff below ground. (Underground stuff shouldn't be used above ground though. Above ground plastics have protection against the uV in sunlight, hence more expensive!)

32mm is fine for that short run, although I think I would do the horizontal run in a bit of 40mm, use a 92.5deg bend, rather than a 90deg elbow, before reducing to 32mm for the vertical, rather than run the lot in 32mm. Less likely to bung up, and easier to clean out if it did.
