Maintain and Troubleshoot Your Reticulation System
A reliable reticulation system is essential for keeping your lawn green and your garden thriving—especially in Perth’s hot, dry climate. With regular maintenance and prompt troubleshooting, you can avoid costly repairs and ensure efficient water use. Here’s everything you need to know about keeping your retic in top shape.
Maintaining Your Reticulation System
Maintaining your system begins with routine inspections. Periodically run your system zone by zone and observe performance. Look out for clogged sprinkler heads, dry spots, soggy patches, or signs of uneven coverage. Identifying early signs of wear or malfunction can help you catch small issues before they become costly.
Flushing is another essential step. Sprinkler heads, nozzles, and filters are vulnerable to clogging from dirt or debris, especially if the water source is untreated. Remove and rinse filters or use a toothbrush to clean nozzles. Replace any that remain blocked.
Test your system regularly to ensure it’s delivering the right amount of water where it’s needed. Adjust sprinkler angles, check arc coverage, and raise buried heads if growth has obstructed their reach. This ensures “head-to-head” coverage and helps avoid brown patches or runoff.
Water pressure should be tested a few times per year. Use a gauge at both static (off) and active (on) states to ensure PSI is within the 30–50 range. Inconsistent or low pressure might indicate hidden leaks, blocked valves, or issues with the main water source.
Over time, sprinkler components will degrade. Look for cracked heads, deteriorated piping, or leaking solenoids. Components exposed to the sun or at improper heights are more likely to break. Replacing heads, risers, or solenoid boxes is straightforward and improves both performance and aesthetics.
Don’t forget about drip systems. These should have filters, air-release valves, and flush valves. Keep emitters spaced appropriately and covered with mulch to prevent UV damage and improve water retention.
Older systems may benefit from upgrades. Stream rotors or rotary nozzles can use 30% less water and are easy to retrofit. Adding rain sensors or switching to smart controllers can help reduce overwatering and improve efficiency.
Troubleshooting Common Issues
Troubleshooting starts with recent activity. Ask yourself: has any digging, fencing, paving, or electrical work been done recently? Many problems trace back to severed wires, punctured pipes, or power disruptions.
Start with a visual inspection. Turn the system on and observe. Are certain areas too wet or dry? Are heads spraying in odd directions or not coming up at all? Check for dripping when the system is off—a possible sign of solenoid or valve issues.
If the system won’t turn on, check the retic controller. Confirm that it has power. If hard-wired, remove the battery to see if the display remains on. Test both manual and automatic settings. If buttons don’t respond or the controller keeps running unexpectedly, it may need replacement.
When only some zones activate, suspect a faulty solenoid, broken wiring, or incorrectly programmed controller. Use a multimeter to test voltage, and ensure wiring joins are sealed with waterproof connectors to prevent corrosion.
If your water pressure is low in all zones, test at the source. A rusted isolation tap or blocked master valve may be the issue. Low pressure in just one section suggests a specific blockage or leak, possibly from tree roots or cracked pipes.
Inspect solenoid valves for leaks or sticking. If a solenoid stays open, other zones may receive little or no pressure. Make sure none are stuck in manual mode. Replacement is often the best fix.
Coverage issues like brown patches often mean sprinkler heads are blocked, buried, or obstructed by plant growth. Clean or raise the heads, and trim surrounding plants. Adding more sprinklers or using wetting agents can also help.
Drip systems can fail quietly. Blocked lines, crushed tubing, or clogged filters can go unnoticed until plants suffer. Check spacing, flush the lines, and replace broken emitters.
Enhancing System Performance
A few improvements can boost both water savings and performance. Swap out outdated spray heads for stream rotors. Install a rain sensor or weather-based controller to automate smarter watering schedules. Bury all wiring in conduit with waterproof gel connectors to avoid corrosion and damage.
To reduce future maintenance, avoid placing pipes or valves under concrete or near large trees. Use sleeving for lines under hardscapes and relocate solenoids to more accessible areas where possible.
When to Call a Professional
Not all issues are DIY-friendly. If you’re dealing with underground leaks, frequent low pressure, non-responsive wiring, or erratic controller behavior, it’s time to bring in a professional. Licensed technicians can also help with:
- Locating buried solenoids and valves
- Rewiring with proper waterproof protection
- Diagnosing complex electrical issues
- Bore pump testing and repairs
- System upgrades and complete overhauls
