Bulkhead leaking

[Phlynamjax]

So I found slow leak on my bulkhead (drain). I used some silicone grease and it stopped leaking, but few days later it started again. I replaced gasket, and it is still leaking. So I replaced entire bulkhead and still leaking. I do not see any damage on the glass. Anything I can do to fix this?

thanks,

If still leaking with a new bulkhead, I would remove and wipe both side with alcohol and new bulkhead as well. Also making sure that the gasket is placed on the westside of the bulkhead. There must be some debris on either side if it's not creating a seal if you said no visual cracks on glass.

Like posted above, check for cracks. Make sure you aren’t over tightening the bulkhead as it can cause the seal to warp and leak.
