[Alberg30] Pump Switches

[George Dinwiddie]

Our PAR freshwater pump has a pressure switch that threads into the pump 
chamber.  I'm sure you could use the same switch mounted in the line 
after the pump, though you may need an small expansion chamber to make 
it all work right.  I bet this switch is available as a spare part, if 
nothing else.

Hmmm...  A short search led me to 
http://www.jamestowndistributors.com/cgi-local/SoftCart.exe/store/product_pages/ITT-371210010.html?L+scstore
where the price for this particular one is almost $35.  Now I know why 
"Prudence" has an ordinary Square D well pump pressure switch in her 
freshwater system.  That's another option.
