Review on 🔧 Square D Air-Pump Pressure Switch 9013FSG2J21, NEMA 1, 30-50 psi Pressure Setting, 20-65 psi Cut-Out, 15-30 psi Adjustable Differential by Louis Asok

I used this part as a last resort to avoid a costly repair on my well or well pump of unknown age and depth. We had water but strange pressure issues. I researched the problem and worked on the pressure tank and well pump switch (this product). Although the problem has improved, it has not been resolved. Then I replaced this part. With normal settings everything works again. I called the plumber, he recommended a nice guy as the next step. Boy am I glad I did my homework and replaced a part that an electrician would have known about. I saved three times the cost of diagnosing home visits. I will buy more parts in the future if I need them.
