sand point well, hill

[jessecolter]

We have a sloped property on a river. Pounded an old school sand point hand pump well about 80 feet up from the river and got great water at about 22 feet deep. 1.25" pipe.

The shop is going up on the hill, about 180 feet from the river where it's approx 25 feet higher. What's a good DIY approach for a second well, pound at same elevation as other one, pump it up the hill?

just curious how are you getting the water out of a 1.25 pipe, as I am thinking about driving a 2" pipe 40 feet for water

32 feet is a vaccuum, so you are going to have to use a submersible pump (not sure what exists for 2” pipe) or a jet, which involves two smaller pipes down the well.

By using this pitcher pump, it might not work for over 25 feet.

You cannot suck water up more than about 24' no matter what kind or size of pump. Deeper than 24' you need a deep well jet or submersible.

I have always wondered about that. Is there a physical law of hydrodynamics or something else that sets that limit or is it limited by the cost of whatever it would take to "suck" hard enough?

With a vaccuum at the top of a pipe the water will only rise 39 feet. <Actually, less than that, because water will boil in a vaccuum, and there are other effects, so I had always heard 32 feet what is the maximum usable height>

Now that right there is some science even I can understand.

Jet pumps don't really suck water. It is all about the atmospheric pressure. The atmospheric pressure pushes water into the intake of the pump. At sea level a pump can draw from much deeper than at higher elevations. At sea level with a perfect vacuum you might get the 32 feet of lift. But most applications and my rule of thumb says any deeper than 25' and you need something other than a shallow well type pump.
