Hello Sir,
There is drop in water level in my borewell. We drilled a borewell of 200ft in which 40ft collapsed and at 155 ft to 160ft, the water in my pump is at 145ft.
We called the borewell professional and he gave us the above details. He also suggested us not to drop the pump further as it can collapse. But my query is if we can hear the sound of water drops from the borewell but then why cant we hear any sound when we removed the pump and pipe out. But as soon as we inserted pump and motor into borewell we canagain hear the water drops sound. The borewell professional told us that those are the vapors which are formed as there is no air inside. We have never heard this sounds before, we can hear this sound only since July.
Can anyone please suggest what could be the problem?
Awaiting for your valuable reply.
