Is there an adapter to connect the black flexible corrugated drain pipe to PVC? I can't seem to find one.

If the black flex drainpipe will fit over the PVC pipe, just put a worm gear ss clamp on it to clamp it to the PVC.

use a fernco but don't tighten down on it too much it will collapse the drain tile. Not the best job but it works. If you can fine a metal sleeve to put inside the corrugated pipe that will help alot and keep it from collapsing
