First of all, you need to know if it’s a concrete pool, a fiberglass pool, or a vinyl liner pool. You should never drain a fiberglass because if the water table is high, it will act like a boat and float up destroying everything. The concrete pool could do the same if the hydrostatic valve at the bottom of the pool is not functioning properly. If the water table is high, even the vinyl liner pools could sustain damage and leave wrinkles. In other words, seek the advise of the pool professional when contemplating draining a pool.
