Hi, Will this work on ESG250N? Looking to replace part R0013200, 2 psi pressure switch. Thanks, Lynn

Hi, Lynn. This Pressure Switch is different from Part # R0013200, however, it can be used as a replacement. You will have to manually adjust the pressure switch to your setting. You will also have to reuse the brass adapter.
