One Patio Block Not Level
I am installing a 28' above ground Doughboy. We had started filling it, and noticed one leg leaning in considerably. There are about 6 inches or so of water in it. We know the paver is sitting too high, would I be able to fix without dis-assembly? Can I dig out under the patio block slightly?
Now is the time to fix it, before any more water goes in the pool. You should have no problem lowering the block and the bottom rails from outside of the pool, even with a little water in it.
Your only concern will be the cove and base on the inside of the pool. It may lower with no noticeable difference, or you may need to pull the liner back and adjust the base and cove. Make your corrections to the block and rails and then check inside the pool. If it needs attention pull off about four top rails and try to pull the liner back. With someone inside the pool holding the liner back you can do any smoothing needed.
This might be difficult with 6" of water but with 2-3 inches it is no problem. And it is better to do this now than to finish filling the pool and wishing you had done it.
