We ordered a 24 foot round pool. Ground was on a slop and had to be dug out. We paid someone to put this pool up for us who supposedly knew what they were doing. Obviously they did not. My water level is off by about 5 and a half inches. Skimmer and return has already been installed. I have called around to installer around me to see if they can fix this. And unfortunately they are booked up till August or September. And say i will need a brand new liner. And I am finding that most places are out of stock. One installer said to backfill the dirt and put up a wooden deck all the way around, as this will keep the pressure from blowouts. We I can get someone to do this as early as tomorrow. Theyvwere originally going to be installing a retainer wall and patio. But they said they are not sure that will be structurally sound. I really don't want to wait till September to have this fixed. And I have lost all trust in the original company. Does this option sound safe.
