Last week, a homeowner in Karrinyup called us frustrated because her front lawn had brown patches everywhere while the back corner was flooding. Her reticulation system ran every morning, but half the sprinklers weren't working properly and she'd been wasting water for months without realizing it.
Turns out three popup heads were stuck, two were spraying sideways into the fence, and one zone valve was leaking underground. Classic Perth reticulation problems - sandy soil shifts, hard bore water clogs nozzles, and sprinklers that looked fine from inside the house were actually broken. We fixed it all in one visit, and within two weeks her lawn was green again across the whole yard.
That's what we do at Alpha Omega Mowing. We're lawn sprinkler system contractors based in Karrinyup, and we fix reticulation problems across Perth's northern suburbs every week. Most issues are simple once you know what to look for, but they waste water and kill lawns if left too long.

Reticulation systems in Perth deal with conditions that break stuff constantly. Sandy soil doesn't hold pipes stable, bore water full of minerals clogs everything, and our long hot summers stress components that were barely adequate when installed.
We see broken popup heads everywhere in Duncraig and Gwelup. They get hit by mowers, clogged with sand, or the spring mechanism fails and they won't pop up anymore. Sometimes they pop up but won't retract, and mowers run over them. Either way, that section of lawn doesn't get water and starts dying.
Cracked or split pipes are huge in areas like Carine and Doubleview. Tree roots grow into irrigation lines looking for water. Ground settles and pulls joins apart. Someone digs in the garden and hits a pipe they didn't know was there. Suddenly you've got a geyser in the garden bed or a soggy patch that won't dry out.
Stuck or leaking valves cause weird watering patterns. One zone won't come on at all, or it runs constantly even when the controller is off. In suburbs like Padbury and North Beach, we track down valve problems weekly - usually sand in the diaphragm or a solenoid that's failed.
Our reticulation repair service handles all of it. We dig out broken components, replace what's damaged, flush lines to clear blockages, and make sure everything works properly before we leave. No temporary patches - proper fixes that last.

We know what Perth lawns need to stay healthy year-round. Proper mowing, seasonal fertilizing, and the right products make all the difference.

If something's not right, we'll fix it. No arguments, no excuses. That's how we've built our reputation across the northern suburbs.

Most of our customers come from referrals. Neighbors see great-looking lawns and ask who does them. That's how we grow our business.

When you call or message, we get back to you quickly. Need a quote? Want to book a service? We don't leave you waiting around.

We're based in Karrinyup and we work these suburbs every day. We know Perth's soil, climate, and what actually works here.

We've been fixing struggling lawns and keeping healthy ones green across Perth's northern suburbs for years.
Most Perth reticulation systems never get maintained until something breaks. That's backwards - basic maintenance prevents most problems and keeps systems running efficiently.
We provide reticulation and irrigation maintenance that actually extends system life and improves performance. This isn't just a quick look-around - it's proper servicing of all moving parts and critical components.
Spraying popup lube on moving parts is simple but makes a huge difference. Popup heads in Karrinyup and Trigg deal with sandy soil full of fine particles. That sand gets into mechanisms and grinds everything down. Regular lubrication keeps springs working smoothly and seals from drying out and cracking.
Cleaning sand out of sprinklers is tedious but necessary. Perth's reticulation systems constantly battle sand infiltration. Heads get clogged, spray patterns change, and water distribution becomes uneven. We pull heads, clean out all the sand, check filters, and make sure spray patterns match what the zone needs.
We check valve boxes for sand and water accumulation. Valves sitting in sandy water corrode faster and develop problems. Clearing that out and making sure boxes drain properly prevents premature valve failure.
Pressure testing finds slow leaks before they become expensive problems. A small leak underground in Hillarys or Sorrento might waste water for months before it's obvious. We check pressure across zones to spot leaks early while they're still cheap to fix.
Regular maintenance catches problems when they're minor. A sprinkler that's starting to stick gets lubed and keeps working. A valve that's showing early signs of wear gets replaced before it fails and floods your garden bed at 2am.

There's mowing, and then there's mowing with proper grass edging. The difference is night and day.
Perth's water restrictions and rising water costs make efficient reticulation systems more important than ever. Old systems waste water, new installations need proper design, and upgrades to water-wise products pay for themselves in lower water bills.
Our reticulation installation service covers both brand new systems and updates to existing setups. We design around your actual needs, not cookie-cutter layouts that waste water.
New system installations start with understanding your property. Lawn areas versus garden beds need different watering. Sandy soil in Gwelup drains differently than clay pockets in Duncraig. Bore water versus scheme water affects component choices. Morning sun versus afternoon shade changes watering requirements.
We zone systems properly so you're not watering shade-loving plants on the same schedule as full-sun lawn. That's where most DIY and cheap installations fail - everything runs on the same program regardless of what actually needs water.
Updating to water-wise products cuts water use without harming your lawn. Modern spray heads and drippers deliver water more efficiently than old gear. Smart controllers adjust for weather instead of running the same program rain or shine. Soil moisture sensors prevent watering when it's not needed.
In areas like Innaloo and Stirling where bore water is common, we install components that handle high mineral content. Standard spray heads clog constantly with bore water - we use designs that resist clogging and are easy to clean when needed.
Proper pipe sizing and layout matter more than people realize. Undersized pipes mean poor pressure and uneven coverage. Bad layouts create dead zones where nothing gets enough water. We design systems that deliver consistent pressure across all heads and cover everything that needs watering.
We also handle reticulation installation for new lawn areas, garden bed additions, or complete property upgrades. From planning through installation and testing, we make sure systems work properly from day one.

Your reticulation can run perfectly on schedule and still not water your lawn properly. That's why reticulation sprinkler testing matters - finding dry patches and coverage problems before your lawn shows stress.
We regularly test sprinkler systems across Waterman's Bay and Marmion, and we find coverage issues on most properties. Heads that were fine six months ago have shifted, clogged, or changed spray patterns. What looked like adequate coverage when installed has gaps now.
Looking for grass dry patches tells us where coverage is failing. Brown spots in otherwise green lawns usually mean a sprinkler head isn't reaching that area. Maybe it's clogged and spraying short. Maybe it's rotated the wrong direction. Maybe nearby heads are overlapping everywhere except that one spot.
We physically check each sprinkler head while the system is running. Does it pop up fully? Is the spray pattern correct? Is pressure adequate? Are there obstructions blocking water? Simple questions, but the answers show exactly what needs adjusting.
Making sure water gets where it's needed involves more than just visual checks. We measure actual throw distance, check overlap between heads, and verify that every part of your lawn receives adequate water. In Perth's climate, missing even a small section means brown patches by January.
Sometimes testing reveals bigger problems. Low pressure across an entire zone points to leaking pipes or valve issues. One head spraying much weaker than others suggests clogging or a failing head. Testing finds these problems before they cost you a dead lawn.
We also test after repairs to confirm everything works properly. Fixed a broken head? We test the whole zone to make sure pressure is correct and coverage is even. Replaced a valve? We verify that zone waters consistently across its entire area.
Regular sprinkler testing should happen at least twice a year - once before summer and again mid-season. Catching small problems early prevents lawn damage and wasted water.


Reticulation controllers confuse most homeowners. Too many buttons, unclear menus, and programs that reset when the battery dies. We get calls constantly from people in Karrinyup and Carine who can't figure out how to set their watering days or change station run times.
Our irrigation controller programming service takes the frustration out of managing your reticulation. We set everything up properly, explain how it works, and make sure your system waters efficiently within Perth's restrictions.
Setting watering days requires understanding current restrictions and your bore versus scheme water setup. Scheme water days depend on your address - odd or even. Bore water has different allowances but still requires smart scheduling to avoid waste. We program controllers to comply with regulations while giving your lawn adequate water.
Setting station run times is where most people get it wrong. They either water too long (wasting water as it runs off) or too short (grass doesn't get enough to reach roots). Sandy soil in suburbs like Doubleview needs shorter, more frequent watering than heavier soils. Garden beds need different timing than lawns. Full-sun areas need more than shaded spots.
We calculate appropriate run times based on your soil type, plant needs, and actual weather conditions. Not guesses - proper times that deliver water effectively without waste.
Programming when stations come on prevents conflicts and optimizes watering. Some controllers let you run multiple stations at once, others can't. We sequence stations so pressure stays adequate, you're not watering during peak heat, and everything finishes before you need to leave for work.
Smart controller features often go unused because people don't know they exist. Weather adjustments, seasonal changes, rain delays - modern controllers have useful functions that save water and money. We set them up and show you how they work.
We also fix programming that's gone wrong. Power outages reset some controllers. Batteries die and programs disappear. Someone pressed buttons trying to change one thing and messed up everything. We sort it out, reprogram properly, and document settings so you can reference them later.
If your controller is old and unreliable, we'll recommend upgrades to modern units that are easier to use and more water-efficient. The water savings often pays for a new controller within a year or two.
Reticulation in Perth faces unique challenges that generic irrigation knowledge doesn't cover. Sandy soil, bore water quality, extreme heat, water restrictions, and specific plant needs all require local experience.
We're based in Karrinyup and work across the northern suburbs daily. That means we know which streets in Trigg have terrible soil drainage. We recognize the water quality variations in North Beach versus Hillarys. We understand seasonal timing - when to increase watering, when to back off, what breaks most often in which conditions.
That local knowledge shows up in how we approach repairs and installations. A homeowner in Padbury calls about low pressure - we already know their area has pressure issues during peak times and design solutions that work with that reality. Someone in Sorrento asks about bore water filtration - we know exactly which filter systems handle the mineral content in that area.
We also understand Perth's actual weather patterns versus what forecasts predict. Controllers with weather adjustment features are great, but they need local knowledge to set baseline watering that actually matches your property's needs.

Some problems show up constantly across Perth suburbs. Knowing what's common helps homeowners recognize issues early.
Popup heads that won't pop up are everywhere in Duncraig and Gwelup. Usually sand in the mechanism or a failed spring. Sometimes they're installed too deep and can't break through soil and grass. Quick fix once we dig them out, but it kills that section of lawn if left too long.
Sprinklers spraying the fence, driveway, or straight up in the air frustrate people constantly. Usually the head got rotated, hit by a mower, or has a broken nozzle. Easy repair, but it wastes water and leaves lawn sections dry while overwatering areas that don't need it.
Valves that won't shut off cause soggy patches and water waste. In Stirling and Innaloo we see this weekly - sand gets in the valve diaphragm, solenoid fails, or debris stops the valve from seating properly. Sometimes the controller is sending the wrong signal. We track down the cause and fix it properly.
Broken pipes from tree roots happen everywhere. Mature trees in Karrinyup and Carine have root systems hunting for water. They find irrigation lines and grow right through them. We locate the break, cut out the damaged section, and reroute if necessary to avoid future problems.
Controllers that won't run programs or keep resetting drive people crazy. Dead batteries, power surge damage, or just old age. Sometimes it's simple user error - wrong mode selected or schedule accidentally deleted. We sort out what's wrong and get watering back on track.
If your reticulation system isn't working properly, wasting water, or leaving dry patches in your lawn, we can help. Our lawn sprinkler system contractor service covers Karrinyup, Duncraig, Gwelup, Doubleview, Carine, Padbury, North Beach, Trigg, Hillarys, Sorrento, Marmion, Waterman's Bay, Stirling, and Innaloo.
Call us or send a message and we'll come have a look. Most problems are obvious once we test the system. We'll give you a straight quote for repairs or upgrades, explain what needs doing and why, and schedule work that fits your timeline.
We carry common parts on the truck for most repairs, so simple fixes often happen same visit. Bigger jobs get scheduled quickly - we don't leave you with a broken system for weeks.
Most of our reticulation work comes from referrals. Neighbors see properly working systems and ask who fixed them. That's how we've built the business - doing solid repair work that lasts and treating people fairly.
Your lawn doesn't have to have brown patches or waste water on overspray. With proper reticulation repairs, regular maintenance, and smart programming, Perth lawns can stay healthy year-round without excessive water use. We've proven that across hundreds of systems in the northern suburbs.
