Shurflo Smart Sensor Pump

[jereswain]

Greetings all. I have a stumper. My Shurflo Smart Sensor water pump is giving me trouble. My water system will act like there's air in the lines (sputtering) then go immediately & completely dry. 5 minutes, 1 hour, 1 day later (there's no rhyme or reason), it will come back on, only to fail again. My electrical connections appear sound. The pump works fine when it decides to. I've detected no leaks where it's housed.
My dilemma is, "Is the pump failing?" or is something else going on? Any experienced advice, suggestions, shots-in-the-dark or psychic predictions would be most welcomed.
Many thanks.

Sucking air.......

As suggested, check suction side of pump----pickup line, strainer, fittings, winterizing valve/fittings

Probably sucking air. Check the line between the pump and the tank including the winterization valve if you have one.

Probably the pump's pressure switch diaphragm or switch itself is faulty or there might be a filter with dirt clogging it causing these symptoms too.
