We have dug borewell upto 280 ft and got water 1.5 inch. We rented motor/pump to test water capacity. Put motor at 240 ft and it worked fine 1 hours then later we put down motor to 260 ft. AT that time neither motor started nor came out. it stuck at that level. It did not started came out by just pulling. hence we called expert to do that.
Can any suggestion what could have been issue for motor not starting and not coming out?
Also what we can do further in order to test water capacity again.
