I’m about to lay a new patio, but I found that the clay drainage hopper was broken, which I have removed. I need to replace the broken one with a plastic one. How do you connect a plastic hopper to a clay p trap I think. It already has a 5 inch collar on it.

you would use a band seal ac4000 or similar
