Noob here trying to get my pool open for the first time. Hayward DE 4800 filter is working properly. Only issue now is that after the Pentair Booster Pump is running for 20 minutes i hear the hose pop right off. The hose connected to the pump outlet is the one that keeps popping right off and at the same it seems like the water is hot when it pops off. Is it overheating? Should I use pvc instead of the tubing that came with the device?
