My pool builder sent out his crew to close my pool on 10/11/13. Today (10/17/13) I noticed a humming sound coming from my pool equipment area. I went outside and found that when the pool was closed they did not shut off the pump, so my pump has been running for almost a week for four hours a day without any water flowing through it. It states right on the pump that running it dry will damage it. Should I make my pool builder replace my pump since it ran dry for almost a week?
