Hi, Everyone, This is my first post here. I got this old vinyl pool (around 10 years) from previous owner of my house. Last year everything was great. And this year 2 weeks after I opened my pool, I noticed a leaking problem. The water is dropping about 1 inch in 12 hours with either the pump on or off. I don't have a in pool light and since it is still leaking even when drops below the skimmer line, I suppose the problem is not in the skimmer. I did notice some kind of sealer fell off from the liner fixture around the steps. I took a picture.
Now the question is, will this cause the leak I am seeing? Also what should I use to seal it again?
Thanks for all the recommendations!!
