We have a 18 X 36 in ground liner pool. When it was installed last summer, the builder forget to place the beads on the back of the liner into the base of the top step of the stadium seating entry (the steps run the entire width of the pool - 3 steps total). Those beads snap into the top step along the wall and keep the liner flush against the wall. As such, the liner on the shallow end entry is not flush against the wall. That is where people enter the pool and I'll feel that eventually someone will put a hole in the liner. I'd venture to say that the liner is only about an inch from being in the perfect position.
Please note that our soil drains very well (very sandy soil - if you dig down about 6 inches, the soil is very sandy). Also, the base of the pool is vermiculite with metal walls.
He has recommended to drain the pool in the shallow end to about 3 inches, so he can pull the liner back enough to snap the liner into the step.
Is there anything that I should worried about happening to the liner? What are the possible unintended consequences to doing a partial drain?
Personally, I want the pool in the condition that it should have been. But I don't want to risk even more problems if that is possible.
Thanks in advance!
