[AT] Off Topic Goulds piston pump

[Larry Goss]

It is a physical impossibility to LIFT water over one atmosphere of pressure (around 28 feet).  You can push it with a submerged or jet pump, but you have to have the actual pumping action (jet, turbine, cylinder, etc, within 28 vertical feet of the top of the water for it to do anything.

Mine will lift about 50' but your comment is quite valid in general.

Of course a "deep well" is subjective to an extent.  Mine is about 50' 
and I'm sure it is a shallow well.  My mom's (more or less next door) is 
at least 250'.  My cousin's (over the ridge) is at least 500'.  I 
remember they had a real problem finding water for the well.

Mom's setup was at one time with a surface pump but now with a submerged 
pump.
