Waste pipe replacement

[Oldboiler]

Hi
I want to replace the 32 & 40mm waste pipes that connect to my external soil stack, not enough fall so not draining. Should I make a new hole lower down below the boss branch to insert the new pipe or is it best to just replace that section completely and connect to the stack a bit further down? I don’t want to be making holes in wall :-0 any advice?

I would say you just have enough fall there , pipe just want doing again and clipped properly. I would use 2x 135 degrees fittings at the stack to bring it back neatly to the wall to give you the correct measurement off the wall

Also looks decent to me. Looks like you have 40mm - 50mm maximum fall overall on the waste pipes, which should be fine at that short distance.
Just new fittings, pipes and several clips needed as above post.

As above but with clips, to be honest push fit pipe to my mind seems to sag due to the plastic type so plenty of clips and all black for appearance. centralheatking

Scaffolding plank would be better if ones available.

Thanks for the tip about push fit. I guess if using solvent weld you have to use it everywhere else? Deffo want it all black
