Leaking Overflow Bulkhead

[Nano]

you'll have to remove it, (if possible) the silicone the gasket to the glass, then silicone the bulkhead to the gasket, then a nice bead around the bulkhead, problem solved. I had the same problem, and now I'm having others

[clowny]

any advice on how to remove it? we tried for 2 hours turning and turning I guess I will just keep twisting and hope it finally starts to losen.

are you twisting it the right way they are trick once they get tightened I found. might have to get your wife to hold from the top and you screw from the bottom, remember righty tighty lefty loosey

[clowny]

LOL yeah we were twisting left the problem is the previous owner glued or sealed the nut to the bulk head thus causing them to twist together.

It is probably not glued. It is probably frozen with salt creep. I used a hacksaw blade on a stick to cut one side. This was very difficult.

I do not think that you can fix it without getting it out.

Good luck

2 channel lock pliers should do the trick

I wish you luck getting it out.

You say the nut is in the overflow ..... I hope this means the bulkhead goes into the overflow from the tank. If it exits the overflow to air, then it was installed backwards and this may be why it leaked.
The gasket goes on the wet side and the nut goes on the dry side. The reason for this is how it seats to the gasket.
Anyway ....
Once you get it out, I'd recommend you buy a new replacement and install it dry. Just past hand tight is a starting point. The gaskets do not like to seal more than once, so make sure you are finished playing with the plumbing before you tighten it.
I learned this when I tried to turn one last month. It would not re-seal.

Silicone may work for some, but it's not recommended as it can cause the gasket to squish out.

any bulkhead i ever used was reverse threaded therefor "lefty tighty, righty loosey" ? maybe mine are odd? +1 on the bulkheads installed backward tho...

It will seem that way when you are dealing with them upside down
