I need to work out how to connect 90mm PVC to the corner grate.

The regular drain is 100mm deep and has provision to directly connect 90mm PVC. I am using the cheaper compact drain that is 80mm deep so I have to do my own thing to connect to 90mm PVC.

Thinking…

OK… going to notch out the top of the PVC so it can slide in under the grate.

Just eyeball and mark the cutout.

That should work, just need to cut out a bit of timber edging.

Back tomorrow to do that as well as some more trenching to line everything up with the correct fall.
