Apparently I have the choice of two popular makes of low water pump
cut off switches, the Franklin "Pumptec - Plus" and the Symcom
"PumpSaver Plus". I have no experience with either and haven't been
able to find a lot of objective information on the net so would
appreciate hearing from people who might have used either of these
switches and your experience. If it makes a difference the well pump
(a Gould 2 hp, 230 volt) is set at 400 feet). If you have a preferred
dealer that would be nice also. Thank you

At 400 feet I assume you have a submersible pump. Do you have typical
setup with Pressure tank with a pressure switch mounted to the tank
If all you are looking for is to prevent dry running the pump, Square
D makes a pressure switch that has a low pressure cut-out. If the
pressure drops below some low value (well below the cut-in value) the
switch will turn off the pump and leave it off. You have to manually
flip a lever on the side of the switch to turn it back on. Looks
exactly like the regular pressure swtich you see on zilllions of well
systems except is has the little lever on the side.
If the pump starts sucking air this will shut it down when the
pressure drops. Also works if your pipe from the pump to tank springs
a leak, provided you don't have a check valve between tank and pipe.
It's not completely foolproof, but it catches most common situations.
That would definitely be the economical solution. Our well guy put a Franklin
controller on one of our more marginal wells. Has about 8 different flashing
codes, including underload which presumably checks for the pump spinning against
air instead of water.
Yeah, I have one of those. It works but has to be reset once tripped,
a small inconvenience. If I put in a 1500 gallon reservoir tank the
inconvenience factor goes off the board. They are also more prone to
not tripping and burning out a pump. That is a $2500 inconvenience.
