Hi Rob and welcome!

I don't know WHICH Aquadoor model I have, but I've had one for my pool for 11 years now. It does occasionally leak--you MUST put it on very carefully, and I would suggest using a Gizmo in your skimmer or filling same skimmer with lots of foam rubber (like a cut up noodle) so that any ice that forms won't break it. Cheap insurance!
