I've read the installation notes for some of the units and mostly agrees with what Sam says. Always solvent weld, never push fit. Definitely go up before going across and avoid sharp elbows. I avoid elbows on ordinary gravity sink wastes etc. Some suggest using pairs of 135 degree bends rather than 90 degree bends but not always feasible. I would consider fitting tees at critical point with end stops for rodding.

Any problems with using 32mm or even 40mm pipe for the whole run, even if it's fairly short? Seems less likely to block than 21.5mm.
