Pool Pump Losing Suction or Prime
If your Swimming Pools Filter system looses Prime, it is caused by one of the following conditions.
Note: The lost of suction/prime is caused a leak which in turn sucks air into the system. The lost of suction/prime will be anywhere from the Main Pool Skimmer(s) to the Pool Pump. It will NOT be from the Pool Pump to the Pools Main Return(s).
1) First make sure that your water level is high enough so that the skimmer is not sucking air.
2) Check the Pump Pot Housing Lid Seal and be certain that its completely sealing and is not
Sucking air into the system. Check the lid for cracks. If either condition is true, replace the Pump Pot Lid Seal and/or entire lid
3) Check all fittings, clamps and hoses from the pools skimmer to the Pools Pump Pot Housing for wear, tightness and leaks.
4) Check Pool Pump Pot Housing for cracks.
If everything aforementioned in good working order, the next thing to check is the Pump Pot Housing Main Seal and the Pumps Impeller and finally the pump.
5) While the Pool Pump Motor is running, carefully inspect the area where the Pump Pot Housing attaches to the Pump Motor. See if there is any water leaking. Next, spray the area with water and see if the water is sucked into the Housing. If so, your Main Seal is damaged.
6) Disassemble the front half of the Pump Pot Housing from the back half and inspect the Pump Motor Impeller. (This is a high suspect part). See if there is any sign of wear or breakage. (This happens over time from debris in the water passing over the impeller). If so, your Impeller is damaged.
7) Re-inspect the Pump Pot Housing Main Seal by standing the partially disassembled upright, with the Pump Motor towards the ground. Pour water over the impeller and into the cavity. See if the water leaks thru to the outside of the Pump Pot Housing. If so, your Main Seal is damaged.
8) Remove the cover from the rear of the Pump Motor. Using a large standard blade, (straight), screwdriver or wrench... turn the main motor shaft. Listen for grinding and/or rumbling and feel for any restrictions while turning. If you hear or feel either, your bearings and/or brushes are damaged.
If everything seems to be in good working order, then you need a new pump... not just replacement parts
