I WANT TO START UP A WELL PUMP THAT HAS SAT UNUSED IN 2 YEARS DUE TO FIRE.
THE WELL IS 440 FEET DEEP AND IS REGISTERED WITH THE COUNTY AS PRODUCING 78 GPM
TOP 20' IS 7" STEEL CASING. FROM 10 -22' ITS GRANITE, 22-30' ITS DG,
30-440 ITS BLUE GRANITE.
AT 240' A 1' CRACK @3 GPM AND AT 425' 1' CRACK @ 73 GPM

MY QUESTION IS SHOULD I TRY TO 'PRIME THE WELL' BY LOWERING THE WELL LEVEL IN STAGES TO ENCOURAGE WATER TO SEEP IN OR DRAW THE WATER LEVEL DOWN COMPLETLY?
I HAVE NO IDEA THE SIZE OF THE WELL PUMP. ALL EQUIPMENT ABOVE GROUND INCLUDING PRESSURE TANK WAS DESTROYED SO I DON'T KNOW THE PROPER TANK SIZE TO USE.I WILL BE PUMPING THE WATER TO 2 -10,000 GAL TANKS EVENTUALLY FOR FIRE DEPT, IRRIGATION, AND 7 BATH DOMESTIC USE.THE HEAD FROM THE TOP OF THE WELL TO THE TOP OF THE 8' CONCRETE TANKS IS 80'. WHAT SIZE PUMP SHOULD I USE INCONJUNTION WITH THE WELL PUMP TO FILL THE HOLDING TANKS? DO I NEED A PRESSURE TANK AT THE WELL HEAD OR JUST HAVE THE WELL PUMP COME ON WITH THE MAIN TANK FILL PUMP AND CYCLE BY MEANS OF A FLOAT VALVE IN THE TANK? THE WELL HAS NOT BEEN OPENED TO MY KNOWLEDGE SINCE IT WAS INSTALLED IN JUNE OF 1987. I BOUGHT A YEAR AGO AND WILL START TO REBUILD THE LOT IN 6 MONTHS.
THANKS FOR THE HELP AS I'VE NEVER LIVED ON WELL WATER.
TERRY
