I have a 5 y/o 86 gal vertical Water Worker pressure tank. It has developed a tiny leak (1 drip per minute) thought the threaded nipple on the bottom of the tank and the 90 degree elbow. What is my best fix for this? I thought about trying to replace the elbow, however then the issue becomes if i cant get it on tight enough or get it on tight and aligned with the slot for my plumbing to go through the stand i might create a bigger problem. Would an epoxy seal this tiny leak better? Are their any products that you have used that you would recommend me trying? Thank you for any help.
