When every zone in a Birmingham, MI system had weak spray and heads barely rose, we traced the issue upstream. Tests confirmed that the pressure drop occurred at the backflow preventer — debris and regulator wear caused a system-wide loss of PSI.
A Livonia sprinkler system sprayed fine mist instead of droplets. Tests showed excessive pressure — over 75 PSI at the heads — causing atomization, wind drift, and wasted water. Installing pressure-regulated heads and a main regulator restored coverage and saved water.
A Troy homeowner’s water bill doubled in one month. System seemed normal until a pressure test revealed a lateral line leak underground. Digging exposed a cracked poly pipe caused by tree root intrusion. Repairing the pipe and adding monitoring restored efficiency.
A Bloomfield Hills homeowner reported Zone 5 never starting, even though the controller showed “running.” Testing revealed the controller only sent 12 VAC instead of 24–28 VAC. Replacing the output board restored full function and saved the homeowner from digging up a perfectly good valve.
