I have a bore well with a 30" cement casing. I need to form an extension and add 6" to riser. It has a 21" cement cap. The riser is only 2" above grade. I want to install a submersible. Do I need to worry about torque?
I presume you will use a 1/2 hp 10 gpm pump. 1/2 hp has less torque than bigger motors.
For sure you want the pump in a flow inducer sleeve.
Will the pump be vertical or horizontal?
Will you use pvc or SIDR polyethylene below your pitless adapter, or if you don't plan to have a pitless adapter, how will you deal with freezing?
Have you figured out how to mount the pitless adapter?
I am not a pro.
I suppose any work will have to be permitted, but do I need a license or can I just do better than code?
I think that is a question for the people that issue the permit.
