Pumptrol Water Pressure Switch with manual reset
This is my standard go to pump pressure switch. I keep a spare on hand in case I need it or my neighbor needs one. Each one I've bought lasts for about 15 years being mounted outside on the pressure tank with little maintenance. I live in Florida so there is no problem with freezing. This model has a manual reset switch with OFF, START, AUTO handle positions. That means that if the water pressure in the system drops below about 20psi this switch will trip off and will not start unless a person holds the lever in the START postion until water pressure reaches over 20psi. At over 20psi the lever can be moved to the AUTO postion and the pump will operate automatically. This manual restart feature prevents damage to the well pump from running dry in the event of a pipe break, a water hose is left on unintentionally, or (in my case) a power outage when some faucet or hose was on. The cost for this model over the automatically restarting switch is only a few dollars.
The only problem I've had with the switch is that in cold or wet weather ants will sometimes get caught between the electrical contact points preventing the pump from starting. turning off the power and cleaning the points solves the problem.
