Pool Liner and Ice


New member

Replaced pool liner for 40'x20' inground Lazy-L back in 2015. Last Oct I lowered the water to about 10" below the returns instead of the normal 2"-3". Everything fine up until 25-Dec when i looked out and saw that the water had dropped sharply - down to maybe 2" of water on the shallow end. The night before it was cold enough for ice to form - as you can see in the photo there's still ice. I suspect the liner was pierced by ice but what I don't get is why wouldn't the damage be at the level where ice would have initially formed - at 10" below the returns. Why would the water have dropped that low?

it may not have been ice.. the hole is at or just above the water line now.. something may have droprd in the pool or somehow a rip or something did it..
