Thanks Larry, I will try the three-quarter inch bold method when removing the nipple (once I have a replacement). I have thought many a night about getting to replacing the nipple, but… I know the consequence of waiting for it to rust all the way through. About 20 years ago I worked in a store where one of these nipples had rusted through while I happened to be in the bathroom 😯 . Luckily I had a towel near by when that happened. I did tighten the flex connector when I noticed it the first time, but that apparently either was too late, or did not solve the problem. Am I looking at replacing the anode at this time too?
Thanks again, Ray
