Hey everyone! New to the forum and seeking help. Just got a local pool company to install a new U-Bead liner on my 48" 15' above ground pool.I wasn't home when he installed it but i know he had a vacuum shop vac to install it. When I got home he had filled the water to 1foot above cove. I noticed a lot of tension as non of the walls were touching (which I guess is normal until water is pushing it against wall). but the problem is that the liner isn't touching the entire surround of the pool cove. I called him up immediately and he told me that it will stretch. He suggested I wait until a very hot day to keep filling it up and that he would come after that to cut out the return jet and skimmer.I got in the pool yesterday and there's seems to be a good 2-3" of distance between the liner and the floor/wall cove. Is this normal?? Can the liner really stretch 3" all around at the cove while there is already above 1 foot of water?? Should he or myself empty below the cove and re-fill water with shop vac on backside? Is there not enuf sand at the cove? Am I paranoid or is this pool company incompetent?any help would be greatly appreciated!
