Connect PVC to 3" corrugated drain

[mf915]

I have a few PVC drain pipes (3/4" in and 1.5") coming out of the house. I would like them to connect to the 3" corrugated drain pipe. I know I need a few of the 3" corrugated tees. Just having trouble finding the adapters to connect the 3/4" and 1.5" PVC to the 3" corrugated tees.

Need some ideas and names of the connectors as i have troubling finding them in those big hardware stores...

Also if possible, I'd like the connections be a bit flexible.. Maybe some flexible coupling ?

Thanks

They don't freeze?

Are you talking about gutter downspouts?

water downspouts too.. but those i can find the flexible connector that goes to the tees.

The PVC drain pipes are from sump pump (1.5") and from water softener (3/4"). I'd like to converge these downspouts + PVC drains pipes to a 3" corrugated drain (down the long driveway) to the backyard.

I guess if it's easier to get connectors to 4" corrugated drain.. i can use 4"

We never use corrugated pipe because it causes more problems than it solves. If you must, transition your PVC to the larger size that is needed to match the piping.
