This is a question about how to connect various drain pipes together.

I've got a 4" corrugated pipe running down the side of my house, to the
street.

I want to connect my sump pump to this pipe, so the water discharge
runs to the street also. But my sump pump uses 2" PVC.

How do I connect 2" PVC to a 4" corrugated pipe?

Thanks,

Chris
