This past Saturday we attempted to install a new liner in our pool after completion of floor repair and new wall foam.
The new liner is from Kafko. It is 18x36 inground. There wasn't many problems hanging the liner other than the break arrows on the liner did not appear to line up correctly with the small tile lines in the bottom.
I closed out the steps with 4x8 plywood and a 2x4 and duct tape. Started two shop vacs to seat liner and I could not get it to pull in the corners. The shop vacs ran for about 25 minutes and the seam for the floor in shallow end at the wall was 4 inches above the floor. Plus the liner was pulled away from the same shallow end walls. It appeared to me that running the vacuum longer would not result in the liner seam being at or near the floor. I stopped vacs and tried to reposition more material into shallow end, but did not help the issue. I measured the side wall and the seam is at 38.5. I ordered a wall height of 42. The dimensions on the box say 42. I believe if the liner was within an inch of requested wall height it would seat better. The air temperature was in the low 70s on Saturday. I have not put in water, because I didn't believe the liner was seating properly.
Any assistance is appreciated.
