How To Fix A Pool Pump That Is Not Fully Primed

In this Pool Care Basics Video, we discuss how to fix pool pump priming issues. A fully primed pump should be full of water. No air should be visible. A half-empty pump is a clear sign that something is wrong.

 

Note: There are cases where a variable speed pump, running on low speed, will not completely fill with water. That is ok as long as the water level in the pump does not continue to drop and run dry.

Common Causes of a Half-Empty Pump

  • Low Water Level
  • Weir Door
  • Skimmer Basket
  • Pump Gasket
  • Pump Lid O-ring/Gasket
  • Suction Side Leak
  • Clogged Impeller
  • Clogged Suction Line

  1. Thank you. I too came back from vacation and my pool pump was not working. However when I primed the pump my with the hose as directed, the pump worked fine. The pump is on a timer, and I noticed it would no longer self prime. I checked the basket,s the weir pool water level the pump did not have water but I could hear water draining and the water level increased,. So I turn the pump on but it didn’t work until I primed the pump with the water hose and I had to manually prime again. Any advice?
