William,
I hadn't thought of the Jobe valves for the primary tank. We see them
used a lot for the
gravity fed stock tanks that are fed by the primary tank though.
I seem to recall being told by an NRCS water system designer that the
Jobes had a problem
that developed after 2-3 years of use. I'll have to look into those a
bit more.
Thanks for the info!

I have minimal experience in this field, but I did experiment with this
type of control. I did not specify a pressure tank, which may have
rendered the concept feasible.
I had suggested a ball cock valve be installed at the tank and a
pressure
switch at the well to control the pump. There is a problem,
however, with this type of valve: I believe they tend to close off
water
flow gradually. When partially closed, enough pressure can build up
to shut off the pump. Because the valve is not fully closed, the
pressure in the line can bleed off rather quickly, causing the pump to
start up again quickly. This rapid cycling can increase wear and
tear on the pump.
There is a valve available that will function in a different manner and
allow this type of operation. It "snaps" closed.

Allan,
Is the distance between tanks too far to consider adding that float
switch wire?
It really is the most reliable way.
What's the vertical lift from pump to tanks? If it's not too much, say
under 60-70 feet, you
could use a float valve in the tank and expansion tank w/ pressure
switch
setup for on/off operation.
My fear with any wireless setup would be the complexity and thus the
reliability of it. And it needs power....
Good luck! Please follow up with anything you find....I'm tired of
running float wire....as much as 14,000
feet for one system (runs fine...for now)
