What causes half of my sprinkler zone to stop working?
The most common reason for half of a sprinkler zone to stop functioning is a blockage in the water supply. This can occur due to dirt, debris, or mineral buildup within the pipes or sprinkler heads. If the system has not been properly maintained, clogs can form that restrict water flow, leading to inconsistent watering across the zone.
Another potential cause may be a malfunctioning control valve or a broken sprinkler head. If a valve is stuck closed or partially closed, it may limit the flow to only certain sections of your zone. It’s essential to inspect all components, including the lines, valves, and heads, to determine where the issue may lie.
How can I troubleshoot the issue myself?
To begin troubleshooting, inspect the affected sprinkler zone by manually activating it through your irrigation controller. Observing which heads are functioning and which are not will help pinpoint the issue. Look for clogs in the heads and check if they pop up and retract properly. This inspection will give you a good idea of whether the problem lies within the heads themselves or elsewhere in the system.
Next, check the water flow by removing the affected heads and inspecting the supply line for obstructions. You can flush out the line by turning on the system briefly to clear any debris. If the heads are clean and the water flow is still weak, the issue might be within the valve or piping, requiring more extensive evaluation or repair.
What tools do I need to fix my sprinkler system?
Basic tools for fixing a sprinkler system include a flathead and Phillips screwdriver, pliers, a hose or pipe wrench, and a digging tool such as a trowel. Depending on the specific issue, additional tools may be useful, such as a pressure gauge to test the water pressure in your system or a wire cutter if you need to make electrical repairs.
If you’re dealing with more complex issues like valve replacement or pipe repairs, you might also need PVC pipe cutters and glue or connectors for reassembly. Having a multimeter can also be helpful for diagnosing electrical problems related to the controller or solenoids.
When should I call a professional for help?
If after your troubleshooting efforts you’re still unable to identify or resolve the issue, it may be time to call a professional irrigation technician. Particularly complex problems such as those involving main lines, underground leaks, or control systems often require specialized knowledge and equipment that the average homeowner may not have.
