Fw: Need a Deep Well Pump Solution [RE-wrenches]

[Brad Bassett]

Allan,

The SQFlex pump only needs 2 conductors and a ground down the well. The 
low water sensor is built into the lead on the pump and is wired to the 
pump where it does it's thing. 

I will get you watthours per gallon for generator and solar direct next 
week.

It sounds like some of the solutions to run off a battery might cost 
more than a solar direct system with it's own array, especially when you 
consider the labor and troubleshooting involved.

In general I do not recommend using flexible hose for well pumps. They 
are generally made with vinyl or rubber, both of which can leach various 
hydrocarbons into the water, and so are rarely rated for potable water 
(Even if vinyl hose is rated, do you trust the raters on this issue, 
also I consider it an environmentally undesireable material). Also, it's 
sometimes hard to find hose rated for the pressures you're talking about 
at that depth. 

Let me know if I can answer any other questions.

Brad
