Mcdonnell&Miller Flow Switches Editorial Review

The 3/4" Water Flow Switch is an essential component that has become popular among commercial water heaters and boilers. The switch is quite sensitive, so it should be installed at a distance of 1/2" to 1" from the bottom of the water flow. When installed correctly, it works great and saves time. The product is highly efficient, with a 120VAC switch rating of 7.4 Full Load Amps and 240VAC is 3.7 Full Load Amp. The pricing is competitive, and the switch has a long lifespan of 5-7 years, especially in areas with very hard water.
