Soil elbow

[datadiyer]

Hi all,

Can anyone tell me how far a 110mm soil pipe 90 degree bend needs to be cemented into an external wall. I have one elbow with push-fit diameter end at 130mm, and another at 127mm. Also what core bit do I Need? Thanks in advance,.

Put some pipe into the bend, put some clips on the pipe and hold it against the wall. That’s how far in/out it needs to be.

Use a diamond core bit 130mm or bigger.

Thank you so much Ian, that makes perfect sense.
Best Wishes.

Bash away the brick/wall if it binds the inside of the bend onto the clipped pipe. It can always be pointed up after... Bigger hole gives you more wiggle room
