[Alberg30] Pump Switches

[Mike Lehman]

I plan to put a deck wash-down pump on our Alberg. I already have a 12v 
Jabsco pump in good condition. I plan to use the fresh water intake 
thru-hull under the galley sink for the supply side. I will run a separate 
circuit to the switch from the panel. When I turn on the switch the pump 
will run. If I use a spray nozzle on the end of the hose, the pump will 
continue to run even though I have stopped the output. My concern is build 
up of pressure causing leaks (or worse) and damage to the pump.

Q. Does any one know of a pressure switch that can be installed in-line (on 
the output side) that would open the circuit once the pressure exceeds say 
10 psi? I have seen pumps with this feature, but I don't need a new pump, 
just the switch.
