My Orbit Sprinkler Timer Won't Stop

Duration Time

• If the timer starts the watering process for one or more zones but they won't turn off, the duration time might be set too high. Press the button to select the correct watering program in question, then twist the dial of the irrigation controller to "Station Duration" and observe the duration time within the display. If the duration time is too long, press the down directional button to lower the time. Some Orbit sprinkler timers feature vertical slide switches or buttons instead of a dial, which might also allow the valve to run manually.

Schedules

• If some stations turn off, but one station remains on, the station in question might have two different scheduled watering times that overlap. Some Orbit timers feature multiple programs, which allow you to set different watering schedules for various areas of the lawn. A station or zone can be scheduled in both programs, and if the two schedule times overlap, the zone or valve remains open until the final program schedule has ended. Select the desired program, twist the dial to "Start Time" and observe the start times for each station in each program. If two overlapping start times exist for the same station, adjust them so that they no longer overlap.

Valve On

• The valve might have been left open from previous drainage, in which the solenoid or the bleed screw were loose or not tight enough. The solenoid is the larger knob toward the "Flow" end on top of the valve. The bleed screw is smaller and is located just in front of the solenoid on top of the valve. Grip both of these and turn them clockwise to tighten and close them off.

Clogged Valve

• If a certain station or zone of the sprinkler system fails to turn off when scheduled, the valve might be clogged with debris and held open. It's possible to fix the valve by removing the debris. First, turn off the irrigation line shut off valve. Twist off the solenoid and lift out the solenoid filter and plunger. Use water and your hands to remove dirt and blockage from these components and then put them back in place.
