My water pump coupling boring type does not lift water from undergroound (30 feeet) to overhead water rank (15 ffet fro ground). the electric motor is working fine. suggest solutions. boring is nearly 12 years old

you have to say what pump you are using
if it is a submersible pump it could be jammed impeller blades and a blown circuit breaker
if it is a centrifugal pump and is not a jet assist pump then the lift head is exceeded to lift water to the pump from suction Most pumps of this type have a max head lift of 10 ft with a 2" suction pipe as the weight of water is too much to lift A jet assist pump is a better option for up to 20 ft
next is the pump primed now if it was pumping before as a bad foot valve will leak the water out of the pump so that it requires priming before it will work
possible it is a jet pump that has a return hose back to the foot valve to assist the pump to lift the bore water higher to work the pump
if that is the case ,when you turn on the tap on the pressure to the lift jet is reduced and so the pump cannot lift the water from the bore --it runs out of water
the fix here is to restrict the flow out of the tap so that jet pressure is maintained--- don't turn the tap on more than 1 turn
the reason is the lift height is too great ,indicating that the bore water level is lower than it normally is
the pump needs priming first as the water in the pipe to the foot valve has drained out ( foot valve held open by sand grains and not sealing off properly)
the bore is empty
water level too low for the pump to lift water
check for water supply to the pump
If it is a bore pump then check for enough water in the bore, injection pressure to lift the water. It may be necessary to control the output from the pump to maintain the injection pressure. ( put a tap on the outlet side and turn partially off)
check for sucking air at pipe fittings
Release AIR lock. Air has got trapped in the pump hence it cannot create necessary level of suction. The way normally you do this by filling the water path of the pump with water and get the air released.
We lived and raised our children in South Dakota. When the big farms started irrigating our 30 foot bored well water level dropped. When we brought this up we were told to dig a deeper well. We could not afford it. 300 foot wells were expensive. We learned how to recycle bath and laundry water. We got our kids raised up.
