Installed Bulk Head but its Leaking

[bkweibley]

I just drilled my first tank last night. Drilling went well. I put the bulk heads on, gasket on the inside, tightened the nut on the back of the bulkhead by hand so that i wouldnt crack the glass, but made sure it was as tight as I could get it by hand. Ran all of my pvc, filled it up and bam! Slow leaks around each bulk head. Why am I leaking there when everything seems great? Do you guys also use silicone behind your bulkheads? This seems like a horrible idea but im not sure of any other way to fix this issue? Any help would be greatly appreciated.

I had the same problem . I sealed the bulkhead on the outside with silicone anyway and no more leaks

Do you have the gasket on the flange side of BH, and not the nut side?
Try some plumbers grease on the gaskets. Plumbers grease is good to use on O-rings and gaskets, helps se

Gasket is on the bulkhead side, inside of the tank. Plumbers grease is safe inside the tank like that?

It's probably to loose or you got something between the gasket and glass. Check and make sure they are clean and then tighten up the nut a little more with some channel locks. I've tightened mine up a lot more then most people and have never broken glass.

I have never had a problem. I use It on pumps O-rings, BH gaskets.

Never use silicone on bulkheads, the gasket should be dry and clean.
