I have a strange issue that I'm having a hard time troubleshooting and its driving me crazy. I have a 21' round 52" above ground Coleman branded pool (basically the same as the intex brand.)
This is the pump and sand filter I'm using:
Amazon.com : Intex Krystal Clear Sand Filter Pump for Above Ground Pools, 3000 GPH Pump Flow Rate, 110-120V with GFCI : Swimming Pool Sand Filters : Patio, Lawn Garden
The 3000GPH version.
Everything will work great when I first turn it on, but over time the flow rate drops. In less than an hour the flow rate goes a trickle. I check the pressure gauge on the sand filter and its in the green. If I turn the pump off, switch to backwash, then the pump performs the full backwash and rinse perfectly. I can flip it back to filter, and I'll get that good flow rate again, and then after a time I'll get the same issue where the flow rate drops off.
Could there be something wrong with the sand filter that's causing this?
