I accidentally dropped a small screwdriver into my overflow earlier tonight and in trying to get it out, rattled my return and the bulkhead started leaking as a result. The bulkhead screw was pretty loose and I was able to tighten it to the point where it's no longer leaking bad but I still see a small amount of moisture forming and there's a small drop every 5 minutes or so. Assuming it doesn't get worse, do I need to replace the bulkhead? Thanks in advance for the advice...
