Recently we put 500 feet borewell in our area, it's hot summer season now. Person who drilled the borewell told me that we can get 1.5 inch of water now. During winter season we can expect at least 2 inch of water. Now we are planning to install the motor at 410 feet and buy 5hp motor with 2 inch mouth.
My question is Can I put 2 inch pipe inside borewell and control water outlet at the end of borewell with 1.5 inch? Whenever water level increase can I increase outlet with 2 inch? Can I control water outlet at the end?
Can we adjust water outlet of the submersible motor at the ground surface or edge of the pipe? Usually people adjust water outlet at the end of motor mouth section which is inside the borewell not at the ground. Is there any signigficance where the reducer kept?
