Called a few companies locally to install a new pool liner. It's about a 10 year old 36k pool and we bought the house last summer, it had come off the coping some. Finally found someone that would do a blue dolphin pool (something about the way it's installed is difficult). Anyway, we were very satisfied with it, looks great. I've balanced the chemicals and we went for a swim today. That's when my oldest found the issue. In the bottom of the deep end, it appears they left something behind under the liner. I would say it's about the size of a medium-sized remote. I can try and get pics tomorrow with the GoPro but needless to say, it's pretty evident when you get up on it. Obviously, a phone call is in order. If it were your pool, how would you handle it? I have no idea if they're going to try and talk me into patching it or living with it. Please advise.
