Hello,
In August 2012, we had a borewell in our house which is under construction. Water struck at 45 feets and we have gone till 170 feets and stopped. The bore width is 4.5 inches. Upto January 2013 water was coming for 5 to 6 hours continously but now the water outflow is not more than 5 mins in 12hrs. Yesterday, we installed a submersile pump V3 1 hp 10 stage model, but still no help. Please advice what could be the issue and how to fix it.
