I just paid a lot of money to a pool contracter to get my pool bottom repaired a new liner put in. Unfortunately the liner has some wrinkles (and it's full of water now). My installer wants to drain the pool at the end of the season (September), hook back up the vacuums, and fix the wrinkles, at his expense.
I know I've read before that messing with the liner after it's stretched out is a bad idea, but wanted to get the opinion of the group here. As far as I know, there is nothing that can be done about the wrinkles with the water in.
