How do you plumb a bulkhead if it doesnt have threads on it? Mine has those little lips on it that look like its made for plastic tubing. But thats not working out too well. My corrugated tubing has a crack in it and I really dont want to have to leave my aquarium off while im trying to get this plumbed the correct way. Answers?

Bulk head is smooth on the inside? For under the tank glue it with PVC glue safe for portable water.
