Hello,

We have dug a borewell at 250 ft depth with water level at 180 feet, 4.5" dia for domestic purpose. The bore company representatives said that at 250ft depth, the bore is surrunded by pebbles and hence we should go for compressor pump. 

Going by their suggestion we fixed a 8Kg/Sq.mt compressor but found that there is still an issue with lifting water as the balance pressure is insufficient. There are no leakages found in delivery, input and jet pipes. 

Please suggest a suitable solution to rectify this problem
