Hello, I just installed my new Krystal Clear Sand Filter Pump - 12" Model SF10110. I don't see any leaks and everything seems to be installed correctly. I have it adapted through the bottom of the original Summer Escapes SFS600 skimmer canister. What is happening is that the water backs up in the pre-filter basket and starts to overflow for about 15 seconds and then the suction finally pulls the water into the tank and then some spills out of the pool inlet plunger and finally shoots out through the nozzle into the pool. It does this over and over wasting a ton of water every 30 seconds. Any thoughts are much appreciated. Thanks!
