Routine irrigation system maintenance helps keep water flowing evenly and can reveal small problems before they damage plants or equipment. Start with a visual inspection of the entire system, including the controller, valves, pipes, filters, and sprinkler heads or drip emitters.
- Check for leaks: Look for soggy patches, unexplained pooling, dripping connections, or water bubbling up around buried pipes.
- Clean outlets: Remove dirt, grass, and debris from sprinkler nozzles and drip emitters. Rinse or replace clogged filters according to the manufacturer’s instructions.
- Inspect sprinkler heads: Make sure heads are upright, secure, and not cracked or obstructed by plants, mulch, or soil. Replace damaged parts and clear obstructions so water can distribute properly.
- Check valves and fittings: Look for corrosion, loose connections, and signs of seepage near valve boxes. Keep boxes accessible and clear of debris.
- Test the controller: Confirm that the display, wiring, and backup battery work, and that programmed zones respond when activated. This is a function check, not a recommendation to change watering frequency.
Run each zone briefly during an inspection and watch for missed areas, misting, unusual noises, or water spraying onto pavement. For drip systems, check tubing and connectors for splits or disconnected lines. Repair problems with compatible replacement parts, and consult the equipment manual when you are unsure how to service a component.
Before freezing weather, follow the system manufacturer’s guidance for draining or blowing out pipes; improper winterization can cause damage. Keep a simple record of inspections and repairs so recurring issues are easier to spot. If a leak is underground, a valve will not operate, or you cannot identify the cause of poor coverage, consider having a qualified irrigation professional diagnose the system.
