i just picked up a predrilled sump and the hole that is drilled is 2 inches. what size bulkhead would i need? i talked to a guy from marinedepot and he said it would be a 2 inch bulkehead, so i ordered one in and its wayyy to big. i put a 1inch bulhead on and it looks Ok but the rubber o ring isnt completely sealing around the all of the hole.

A 1" Schedule 80 bulkhead takes 1-7/8" hole.

i think im gonna try the heavy duty 1'' which reqires a 1-7/8" hole. im just not sure what makes it heavy duty. hopefully it works.
