Re: bulkhead question

Does it matter which way the bulkhead is installed as long as the rubber grommet is on the wet side?
I'm a little short on space and it would be nice if the longer end of the bulkhead was inside the sump, rather than sticking out.
Thanks

As you mention, bulkheads are designed so the the rubber grommet is on the wet side. They are also designed to have the threaded side on the dry side. There are two problems with having the threads on the wet side.
1. when turning the nut it will be turning against the rubber grommet which could cause it to kink and leak. It would also make it harder to tighten sufficiently.
2. As was mentioned by jlfnjlf it could cause the bulkhead to leak through the threads.
You would be better off cutting off some of the bulkhead end or putting the bulkhead in completely backwards with the rubber grommet on the dry side instead. IME this would have a less chance of leaking. BTW don't over tighten the bulkhead nut as some of them crack very easily (

from experience).
