I am trying to source some thin wall plastic piping to act as a
protective sleeve where other piping passes through brick and blockwork

The holes I have laboriously bored are 51mm dia.

2" solvent waste pipe from Wickes is too big. Somewhere I got the idea
that push fit and solvent pipe have different diameters.

Can anyone kindly tell me what I should be searching for?

The back up plan is to run the circular saw down the cut off lengths but
I'll wait to be properly informed:-)


That's what I'd do - but I don't usually sleeve waste pipes through
walls, possibly as I tend to overdrill the holes so there's minimal if
any pipe-wall contact. Maybe I should?

The other thing I have done is to wrap a bit of plastic DPM (heavy gauge
plastic) around the pipe and foam it in, but that also works better if
the hole is over sized. That still allows the pipe to move slightly and
be removed if needed.
