Everyone,

Thanks for your help. I just drained it myself (a friend let me borrow a pump that did it very quickly) and now I'm filling it back up again.

My pool builder has been a pain in the neck but fortunately, I held back the last 15% payment to him for stuff like this. I was tired of arguing with him about stuff that he needed to do. I'm just going to deduct the amount (including my time) from the last payment.
