Is it okay to install an above ground pool partially inground?
Yes, although it voids any factory warranty that came with it. I bought a 12x24 above grond pool, 4 feet deep. I used a backhoe to dig & a transit to level the hole. I buried it to 3 ft. Built a deck all around it & it's been in the ground 10 years now. No problems the only caution is when the pool is filled with water, be very careful when back filling the dirt around the walls. I did it with a Bobcat & almost caved in & destroyed the enitre job. Other than that, no problems
