I am trying to install a J bead liner in my pool. The liner has come loose in a couple of spots on the pool 2 seperate times. I have laid the liner over the metal ring and installed the plastic pieces over that and installed the top back on the pool and started putting water in. When I have gotten about 2' of water in the pool, it has come loose from under the plastic (Twice in two different places). Any suggestion's? It is getting awful expensive on my water bill to fill it up that much and have to drain it all over again.
