My pump just doesn't seem to be pumping much water. The pump basket does not fill completely. I don't have any air bubbles in either the pump basket or the returns. I can isolate the suction side to: spa, skimmer or main drain individually, and have the same problem with all 3. The 3 way valve for suction selection is about 1 foot from the pump inlet, the line is clear, as is the valve. I have had the wet end of the pump apart and checked for debris in the impeller etc. All looks good. Pressure on the filter gauge is normal and filter is clean. Have checked and cleaned the Nano screen and also bypassed the heater.....still very low flow. I need to run the pump at 2500 to get much flo at all and even at 3450 still not enough to run the infloor.
I previously was able to circulate at 1200 with good results.

Sorry you didn't get a reply earlier from the forum. Let's see if you still need help. No indications of air, lines appear clear from what you can tell, same results from various valve settings ..... any chance you have a partial blockage before that 3-way that goes to the pump? Just enough to slow things down but in a location you can't feel or see? Have you tried pushing water backwards with a hose to see if there is any change? This is assuming you still have that problem.
