I have slip 1'' bulkheads in my two overflows. Do I need to glue the connections inside the overflow sections? Should't really matter if it leaks in there right?
I know I will glue the pipes coming out of the bulkheads under the tank in the stand of course.
Thanks!

Only the outside where you don't want water leaking out
