Subject: RE: sand point well with windmill

southern MN
There are pumps on the surface that suck, they can kinda go 20 feet down for water. They need good maintinence to be able to suck water up from their limits.

There are jet pumps on the surface that circulate water to suck much better, to maybe 75 feet.

There are rotary submersible pumps you drop into the water and they push the water up the pipe, can be 400 feet, 800 feet, whatever deep.

Piston pumps are what windmills use, can be at surface or in the hole below water, follow about the same rules, 20 feet at the surface, or whatever down to the bottom of the well. However they need a piston rod in the hole to pump up and down, and are generally bigger than the common 2 inch sandpoint well.

Sometimes there is a pit dug over the well, and the pump is installed on the bottom of the pit, not in the well but below the frost line. This lets you use an above ground pump but it is actually below the surface in that little room. There are issues, the pit is dank dark and humid, rusts everything. And many locations no longer allow a pit over a well, as surface water can wash into the pit and into the well.

It sounds like you would prefer a submersible pump of whatever style you end up needing.

You need all the measurements and the pieces to match each other.

What is your water level, what is your well depth, and then what is the well diameter?

With that info folk that know a lot more than me can piece together the parts to see what can work.
