How are my numbers?

I usually get at least a foot-thick 40'x16' block of ice in my pool and have never had my Aquadoor damaged by it. I also disconnect my skimmer and put a Gizmo in it. I just closed today after 7 seasons and used the Aquadoor in each of them.

I'm in north Jersey about 25 miles due west of NYC.

I drain the water well below the skimmer, to at least 2" below the returns.

Perhaps that was my downfall. The store salesman said that the Aquadoor negated the need to drain the pool, thus saving bucks on having to fill it up again in the spring. My water was up around filter level when it froze.
