Roy:
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. Below is a link to the
brochure:

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)
