My borewell is in Thapathali, Kathmandu, Nepal. The bore is 4"diameter, the depth is 44 feet which was done on May 23, 2012. At that time water supply was 1.35 min for 6.35 gallons water. All of sudden from September 25th the water flow went down and took double the time to fill up for the same amount of water. If I increase the ball valve (water flow) then water stops just after 1.3min. I kindly request you to provide me some suggestion. Waiting for your kind information.
With best regards,
