Hi. I was hoping for some help.
I have been having issues with my pool sweeper (side suction) working well. It always seemed to work better when I cleaned my filters. I recently purchased new pleatco filters and everything was working great. My pressure on the filter dropped from 20 to around 10 and the sweeper worked great. Today I threw it in the pool, got the air out and switched from Skimmer to cleaner and the pressure dropped to zero and all the water from the pump basket emptied out. I removed the sweeper hose and put my hand over the suction hole and there just about zero suction. I tried going from Skimmer back to cleaner again and same thing. The Skimmer is working great. Awesome water flow from the returns. It just seems like nothing works when I change the valve from Skimmer to cleaner. Anyone know what the issue may be?. Thanks in advance.
