I have a 24ft round abg. Installed the liner and started filling yesterday afternoon, had shop vac running all night to suck the air out. Went out this morning had about a foot of water in the pool. Shut the vac off and the walls on the skimmer side pulled in 3 inches. I immediatly started the vac again and got in the pool and tried to push the walls out but they spring back in. Should I drain the water and start over or as the water continues to rise will it push the walls out?
