Hello friends: I have recently developed a suction side issue which I am having troubleshooting. The filter basket is never full as it used to be, and I seem to be getting only about 75% suction. I have isolated all suction-side lines (vacuum, main, skimmer) which results in no change. Pump itself is only a couple of months old. Maybe the impellor and/or housing? I would appreciate any ideas. Thanks, Mike
