Cannot stop bulkhead leaking!

[duncangweller]

I believe it is a 1 3/4 hole. When I had the tank set up in my old place there was a minor leak around the bulkhead which stopped after a few days. Since I have moved o can't get the thing to stop leaking.

Also, now that I have tried a gasket on both sides I can't get the bloody nut off the outside.......aaaaaaarrrggggghhhhhh!

Are you sure there are no chips? When drilling our returns the final punch through caused about a 2cm X 2cm chip which caused for some major head aches. Although it makes the bulk head practically impossible to remove after silicone will work wonders to stop the leaking.

Don't over tighten though, this is a very fast way to break your glass.

+ 1 totally agree, it's not unusual to get chipping on the punch through and the silicone seems to do the trick.

Not unusual but when it happens you look at the person drilling your $2500 tank with what I can only consider laser beam vision...

use a threaded male adapter on the inside of the bulkhead to assist in removing the outside nut....should help stop the spinning....assuming your bulkhead is double threaded...

i would try the rubber gasket on the inside if only one came with the bulkhead fitting

You'll save yourself a lot of grief by using a Sch80 bulkhead rather than the cheap thin ones you get at most LFSs. They have courser threads and thicker gaskets and aren't nearly as finicky as the ones you're using. Only down side is you'll have to use a smaller size as they require larger holes but you can use bushings/reducers before and after to maintain existing pipe size so the effects are pretty minimal.
