I have 1.5" bulkheads for my overflow.. It came with two gaskets. I know I'm suppose to use one in the wetside.. I never seen bulkheads that come with two gaskets.. Do i skip the second gasket or use it on the dryside too, before the nut?

Is it the same gasket? Some do come with two. One for the wetside one for the dry, but the one for the dry side is more of a ridgid plastic.

Some schedule 80 bulkheads come with 2 gaskets, but you only need to use one under the flange. Never had a schedule 40 come with two..

I have been extremely happy with them. Gradually replaced all of my sch 40 ABS bulkheads. You do have to put some molycote 111 on the o-rings and hand torque them down well.

Yes. They claim to be sch 80 but have the same dimensions as sch 40, so not sure how that works; but they are heavier and more robust feeling and made from PVC rather than ABS.
