Case Study — Zone Wouldn’t Shut Off (Valve Diaphragm Grit Blockage)
A Troy homeowner’s zone stayed on after shutoff. Measurements confirmed grit in the valve diaphragm — here’s how it was fixed.
Case Study — System-Wide Low Pressure (Upstream Restriction & Backflow Issues)
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.
Case Study — Heads Misting Everywhere (Overpressure & Need for Regulation)
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.
Case Study — Hidden Leak Caused Sudden Water Bill Spike (Lateral Line Break)
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.
Case Study — Controller Output Failure (Zone Wouldn’t Start Due to Weak Voltage)
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.
