I have an above ground 15x30 pool. One week ago one the Buttress raised out of the ground thus, lifting the post and cap etc. above. To keep the level I sawed off the top of the post and put the cap back on. Today, the one next to it did the same thing but only about 2 inches. Is my pool going to collapse? How could I fix it? Thanks
I would take this very seriously. Examine the situation very closely and decide if you think the pool is safe.
From what I have heard I would drain ASAP and make repairs. But I have not seen photos and I am not there.
Consider the liner when draining the pool, if that is what you decide. Draining the liner dry will probably ruin it. It will shrink and not refill.
A lot of repairs can be made with six inches of water left in the pool. Even if it takes a person inside the pool holding the liner back away from the edge.
If the liner is ready to be replaced, drain the pool, make all necessary repairs and install a new liner. That is the easiest way to do it, but not always the option you want to go with, expense wise.
