Review on Square Schneider Electric 9013FSG2J24 Differential by Casey Vance

What can I say, it's a switch. I've found that some of my sprinklers lose pressure after about 15 minutes of watering. I looked at my gauge and it dropped to 20psi. I have a large yard and didn't realize the people who installed my fountain only had 20-40psi of pressure in the system. Given the number of sprinklers I use per station, that's definitely not enough. After setting this 40-60 I have no pressure drops and the sprinkler heads stay up and spray. The only thing you should do is take a picture of your wiring before replacing it with a new one. Great product and works like a charm.
