Too many sprinklers are operating at one time.
Check to see that the controller is only running one valve at one
time. The system hydraulics may only be capable of single
valve operation. If you find that all the sprinklers are located on
one circuit, an additional valve may be required to better meet
maximum hydraulic flow rates.
System gate or master valve is not fully open.
Locate the gate or master valve and open.
Obstruction in the mainline pipe.
Isolate obstruction and remove.
4. Valve will not turn on electrically.
Controller not supplying power to valve.
Check the controller for output power to the valve. If no power
is detected at controller, then service controller. Check power
input at the solenoid of the valve. If output is detected at the
controller, but no input is detected at the solenoid, then a power
wire is broken or damaged. Isolate and repair.
Main water supply is turned off.
Locate main gate or master valve and open.
Solenoid problem.
If power input is detected at solenoid, but valve still is not oper-
ating, then turn off the water supply. Without cutting wires,
swap solenoids with the next valve (if present). If other solenoid
operates valve, replace solenoid. If other solenoid does not
operate valve, continue troubleshooting.
