My son and daughter-in-law, had a big leak and unfortunately, it was their second. They didn't realize that their insurance company kept their rate the same but raised their deductible from $500 to $5000 (at least that's the story I got). Anyway, upstairs leak, drywall torn out and they have no money. They did have a plumber come out and tell them the seal on the tub overflow was leaking and had to be replaced. This is a deep tub with an access panel. I removed the panel to see glued ABS pipe with a 90 elbow going into the overflow. Coming into the tub out of the 90, is a 1-1/2 threaded nipple. (Could be 1-1/4 and could be a straight thread, I didnt measure). There was a plastic chrome cover over the overflow nipple that was loose. I pulled the cover off and that left a threaded nut like adapter thing that is supposed to tighten the nipple to the tub. On the backside of the tub, where the 90 is and what the nipple is coming out of, there is a wedge shaped seal. I'm a retired pipefitter and I've done more than my share of residential plumbing, I'm guessing this isn't rare, but I've never seen one like this before. I'm wondering if the nipple is a standard threaded nipple of if it's straight thread? Is it threaded into the 90 or is it glued? The seal actually looks OK but feels more like foam than rubber, so it probably should be replaced. The hole through the tub is just big enough for the nipple, so I can't sneak a new seal over the nipple and through the hole. I would either have to remove the nipple if it does unscrew. Or cut the pipe and fit a new overflow. Anyone familiar with this type of w/o? Can you tell me if the nipple unscrews? Where can I get a new seal. Thanks!!
