Hello. 1st post here. I just installed a 24' 25 gauge liner with a 52" wall height. When I installed the new return and skimmer basket I didn't stretch the liner down during their installs and I fear that it's not going to hold. Also, the liner I bought says 52" walls but doesn't say what the depth the middle can be. When I originally installed it I went down at least 12" in the center. Now that the pool is filling it looks like the liner is extremely tight already and it's only filled about 6" on the walls. I'm hoping the the vinyl has enough stretch to it. I have to truck in the water for $300 per 7,000 gallons because I'm on a bored well. I'm worried that when the water is pumped in from the truck that it will not hold. Any words of advise or wisdom would be greatly appreciated.
