Putting in an en-suite, I did all of the 40mm solvent weld plumbing back to the soil stack, but left the final fix of a shower tray to a local plumber.
However, where a 135-degree tee had been left for a ventilation pipe to an air admittance valve (due to the length of the run to the main soil stack), he solvent welded in a 40mm PolyPipe access cap. Not sure that this will now pass building regs as the inspector kept going on about needing AAVs.
This has a cap that screws inside the fitting (rather than screwing outside the fitting), so it won't fit a 32mm pipe or anything inside due to the thread.
Whereas I'd usually just chop it off below the fitting, as he's welded it straight in to the 135 tee means this is nigh on impossible. Also, the other ends of the 135 tee have a flex pipe to the shower trap, and the other straight in to the stub of a 45-degree conversion bend which is half cemented in to the wall, so I can't take out the whole tee...
Any suggestions as how to continue attach the vent pipe other than coring a 22mm pipe through the cap with plenty of silicon and defeating the benefit of the AAV?![/img][/i]
Many thanks!
