Our pool was opened as usual by our pool company. The water remained cloudy and the pool bottom was never cleaned despite multiple back washes and chemical checks. After a month and a half, we finally opened the DE filter tank and to our surprise found no filter in it. Just water inside the tank. We realized that we had no filtration for all this time and even the DE we added after the backwash ended up in the pool. The pool company had removed our filter and never replace it and didn't tell us about it. We had them come back for a service call to replace a cracked chlorinator, but even then they didn't say anything to us. I am concerned that running a pump almost continuously for 45 days could have caused damage to the pump and the impeller. Is it reasonable to assume that damage has occurred?
