I’ve said before I can’t take care of the pool financially, hardly. July 4th my daughter accidentally let it run dry until it was sucking air for a good hour. It came on and things worked but then slowly stuff started happening. I had to replace the backup valve on Polaris last week. Then last night water started shooting out of the new valve again and it wouldn’t move. I disconnected it from the wall and checked things out etc then out of no where the booster pump started making an AWFUL sound. A grinding type sound. I turned it off immediately and that was late last pm so I’ve not got to look it over but I’m pretty worried. I will post a video of it and the sound later. Then the filter doesn’t seem to be filtering at all. There was no DE coating the cartridges and there should be. It’s become a disaster and I’m really scared. All advice is needed and appreciated..
