Reticulation Maintenance: How to Keep Your System Running Year-Round

A well-designed reticulation (irrigation) system should make life easier—not leave you chasing dry patches, leaks, or mystery puddles. The secret to reliable, year-round performance is simple: a little maintenance, done regularly, prevents the big (and expensive) problems later.
Here’s a practical guide to keeping your reticulation system running smoothly through every season.

1) Do a quick “walk-around” once a month
Turn the system on zone-by-zone and watch what happens. You’re looking for:
Blocked or dirty nozzles (uneven spray, weak output, misting)
Misaligned heads watering paths, fences, or driveways
Sunken or damaged sprinklers (often from mowing or foot traffic)
Leaking fittings or valves (wet spots, pooling, or hissing sounds)
Catching small issues early is the difference between a five-minute fix and a blown section of pipe.
2) Clean filters and flush lines
Many systems—especially drip irrigation—have filters that trap grit and debris. A clogged filter means reduced flow and poor coverage. Clean filters at least seasonally, and after any work on the mainline. For drip systems, occasional flushing clears sediment that can build up and block emitters.
3) Check pressure and coverage (they’re not the same thing)
If you’ve got low pressure, sprinklers may not pop up fully, rotators won’t rotate properly, and coverage becomes patchy. Common causes include:
Leaks in the line
A partially closed isolation valve
Blocked filter
Pressure changes from other water use on the property
If you’re seeing inconsistent performance, it’s worth getting the pressure tested so the system can be tuned correctly.
4) Adjust your controller seasonally
A controller set for summer will overwater in winter—and a winter schedule won’t keep up in heat. Update your run times as the weather changes:
Spring: ramp up gradually as temperatures rise
Summer: shorter, smarter watering (often early morning)
Autumn: reduce as nights cool and evaporation drops
Winter: minimal watering, or switch off if rainfall is consistent
If you have a smart controller, make sure it’s connected properly and set to local conditions.
5) Look after garden bed drip zones
Drip lines can be covered by mulch, so problems are easy to miss. Watch for:
Dry plants at one end of the line
Damp patches from split poly or loose fittings
Chewed lines (pets and rodents can be culprits)
Pressure-compensating dripline and a good filter make a huge difference to long-term reliability.
6) Book an annual professional service
An annual check-up can include valve testing, head upgrades, controller optimisation, leak detection, and efficiency improvements. It’s also a chance to fix “slow leaks” that waste water quietly over time.
With routine checks and seasonal tweaks, your reticulation system can run efficiently all year—keeping lawns lush, gardens thriving, and surprises to a minimum.
