Pump with Pressure Switch

I want to use a pressure switch to turn on and off my irrigation pump. What pressure switch should I use?

Answer:
It all depends on……
What pressure do you want the pump to turn-on at &
What pressure do you want the pump to turn-off at?

The most common and inexpensive pressure switch on the market is the “Square D” type. Below are the various modes for the various pressure settings.

On 20-Off 40 psi # 9013 FSG2 J20 standard switch
On 30-Off 50 psi # 9013 FSG2 J21 standard switch
On 40-Off 60 psi # 9013 FSG2 J24 standard switch
On 50-Off 70 psi # 9013 FYG2 J33 medium duty switch
On 60-Off 80 psi # 9013 FYG2 J25 medium duty switch

One word of caution: Don’t play with the pressure adjustments, unless you’re a qualified professional. The adjustments are very easy to mess-up, thus potentially damaging your pump.
