ONE AND A HALF WEEKS AGO..OUR PUMP STARTED LOSING PRESSURE AND KICKED ON EVERY 30 MINUTES AND STEADILY GOT WORSE. TRIED SEVERAL THINGS, BUT NOTHING WORKED. INSTALLED NEW BLADDER TANK, NEW PRESSURE SWITCH AND GAUGE, BUT NOT MUCH HELP. THEN OLD PUMP QUIT PUMPING SO REPLACED WITH NEW PUMP, MOTOR RAN BUT PUMP DID NOT PUMP ANYTHING. THIS IS A DEEP WELL JET PUMP/FOOT IS 65 FOOT DOWN AND WAS REPLACED 11 MONTHS AGO. AFTER NEW PUMP WAS INSTALLED AND ADJUSTED, IT HELD PRESSURE AND WORKED FOR ABOUT ONE WEEK...THEN STARTED SAME PROBLEM--LOSING PRESSURE AND HAS STEADILY GOTTEN WORSE. PUMPS FOR A MINUTE OR TWO AND SHUTS OFF UNTIL PRESSURE DRAINS OFF. ON OLD PUMP, WHEN IT KICKED ON, PRESSURE GAUGE KICKED OVER TO 60LBS, KICKED OFF AND GAUGE DROPPED TO 43LBS, WHEN IT GOT TO 30LBS, PUMP KICKED BACK ON. GUESS THIS WAS OKAY.?? WITH NEW PUMP, WHEN IT HITS 30LBS, THE NEEDLE STARTS JERKING AND DROPS TO 24LBS, PUMP KICKS ON, SLOWLY BUILDS PRESSURE TO ABOUT 50LBS, KICKS OFF AND FALLS TO 43LBS, PRESSURE STEADILY FALLS OFF AGAIN. I HAVE DRAINED TANK TO BLEED AIR, NO AIR IN HOUSE LINES, TURNED BALL VALVE AND ISOLATED HOUSE, PRESSURE STILL DROPS, DON'T HEAR WATER RUNNING IN WELL AS IF LEAKING..IF IT'S THE FOOT VALVE, WHY DID IT WORK FINE FOR ONE WEEK AND START AGAIN??? PLEEEEEEEEEAAAAAAASE HELP ME!!! I AM GOING CRAZY!!! I SOOOO APPRECIATE YOUR HELP. PS--THIS IS A FLOTECH PUMPAND WELLSAVER BLADDER PRESSURE TANK.
