Bulkhead put in backwards?
 

Heres the situation, I know it is only a difference of about 1 inch, but I need to put the bulkhead for my sump in backwards? threads and screw piece would be inside the sump, gasket and black female threaded end on outside.

Has anyone else done this? do I need to add an additional gasket to the inside? will it leak?

thanks for teh help!

I have done it before and sometimes it works fine and sometimes it doesn't.....I believe it depends on how good the gasket is on the Bulk head!

I just did it (gasket on the inside) a few days ago and, well, that part is not the leaky part of the system

i had the bulkheads in my 90 upside down for 3 years with no leaks, i also needed the extra space.

works fine, just remember gasket always goes on the bulkhead side in or out (sorry had a blond moment), and add a film of silicone to all the parts befor you assemble it for added insuranced.

Gaskets go on the outside, not inside?...... good thing you let me know!

Gasket always goes on the wet side.

You are both half right..the Gasket goes on either side depending which way you choose to put the bulkhead it.
If the threaded part is out the gasket is on the inside. If the threaded part is in the gasket is on the outside.
Basically push the gasket onto the bulkhead and then install which ever way you want.

Muck, is what J syaing correct, gasket is on the wet side, no matter which way the thread is pointing?

If the threads are pointing to the inside of the tank the gasket goes on the outside of the glass.

If the threads are pointing outside of the tank the gasket goes on the inside of the glass.

The gasket always has to be against the flat part of the bulkhead itself.
