Water Pump Pressure Switch Replacement

If you draw water from Lake Murray S.C. for your lawn irrigation or sprinkler system, sooner or later you will need a Water Pump Pressure Switch Replacement.  When water pressure drops in your bladder tank when a spigot or the irrigation is turned on, this switch will turn on the water pump at a certain pressure level.

The Water Pump Pressure Switch can fail for a number of reasons.  If you look at the contacts on the inside of this (high voltage) box, you will see where the electrical connection is made.  If, at one of those connections you see black or corroded terminals, it should be replaced.  One interesting cause of failure is ants.  Ants will nest inside these warm areas and sometimes burn at the terminal causing a bad connection.
