Hi, I was just outside adding some chems and noticed directly under one of the upright caps on the inside of the pool under the liner is a lump about 1.5 inches wide that runs all the way down. When I press on it I can't tell what I'm feeling...screws or what but I have not seen this before and I think I would have noticed it. Help????
This pool was installed about mid April.
