I've got a Pentair 340042 SuperFlo High Performance Energy Efficient Two Speed Pool Pump, 1 Horsepower, 230 Volt, 1 Phase pool pump. When I run it on high, the strainer basket fills up and maintains a full level. But when I switch it over to low, the water level eventually drops to below the level of the water inlet. It's obviously not starving for water and I ran it that way all last year, but I'm wondering if this is normal. Anybody have any input on if this is normal. And if not, what's going on and how do I fix it?
Thanks....
