Sprinkler Repair for Western Oregon Systems

Irrigation systems in the Willamette Valley spend eight months sitting idle through rain and the occasional hard freeze, then get asked to run every day through a bone-dry July and August. That on-off cycle is hard on plastic fittings, valve diaphragms, and wiring, which is why most sprinkler problems show up right when you need the system most: the first hot week of summer.

We repair systems of every age and brand, whether we installed them or not. A technician walks the zones with you, runs the system, finds the failure, and fixes it on the spot whenever parts allow. If the system is too far gone to be worth patching, we will say so plainly and walk you through what a new sprinkler system installation would look like instead.

Common Irrigation Repair Problems We Fix

Most service calls come down to a handful of failures. Here is what we see most often across Portland, Salem, Eugene, and Corvallis:

Broken or Clogged Sprinkler Heads

Mowers, car tires, and winter freezes take out more heads than anything else. A broken head either geysers water into the air or quietly floods one spot while the rest of the zone runs dry. Sprinkler head replacement is usually quick: we match the head type and nozzle, set the spray pattern, and adjust coverage so water lands on grass instead of the sidewalk.

Leaking Valves and Stuck Zones

A zone that never shuts off, or a soggy patch that stays wet even when the system is idle, usually points to a valve problem. Worn diaphragms, debris in the valve body, and failed solenoids are the usual suspects. We rebuild or replace the valve and test the zone until it opens and closes the way it should.

Dead Zones and Low Pressure

When a whole zone goes quiet, the cause is electrical or hydraulic: a cut wire, a bad solenoid, a failed valve, or a cracked lateral line bleeding pressure underground. Low pressure across the system can also mean a leak in the main line or a partially closed backflow valve. We trace the problem methodically instead of digging up half the yard on a guess.

Controller and Timer Issues

Controllers fail after power outages, battery deaths, and plain old age. We repair wiring faults, reprogram schedules around Oregon's watering season, and replace outdated timers with modern app-based controllers that adjust run times to the weather, so you stop watering during a rainstorm.

Spring Start-Up and Winterization

The two most important service visits of the year happen when the system is not even running. In spring, we pressurize the system slowly, check every zone, clean and adjust heads, and reset the controller for the season; catching small problems in April beats finding them in a brown lawn in July. In late fall, we shut the water down and blow out the lines with compressed air so trapped water cannot freeze and crack pipes or valves over winter.

A repaired system only pays off if the lawn under it is healthy too. If your grass is patchy even with good coverage, our lawn care programs handle the feeding, moss control, and aeration side of the equation.

Common Questions About Sprinkler Repair

Why is one zone of my sprinkler system not working?

A single dead zone is almost always a valve or wiring problem: a failed solenoid, a cut or corroded wire, or debris stuck inside the valve. Occasionally a crushed lateral line is to blame. We test the electrical path first, then the valve, so the fix targets the real cause.

How do I know if my sprinkler valve is leaking?

The classic signs are a zone that drips or runs after the controller shuts it off, a constantly wet area near the valve box, or a water bill that climbs for no reason. A worn diaphragm or trapped debris keeps the valve from sealing. Most leaking valves can be rebuilt without replacing the whole assembly.

Do you winterize sprinkler systems in Oregon?

Yes. Even in the Willamette Valley's mild winters, a single hard freeze can crack backflow devices and shallow pipes. We shut off the supply, drain the system, and blow out each zone with compressed air in late fall, then bring it back online with a full checkout in spring.

Should I repair my old sprinkler system or replace it?

It depends on the failure pattern. One bad valve or a handful of broken heads is an easy repair. But if the pipes are brittle, zones were laid out poorly, or you are calling us every month, replacement often costs less over a few seasons. We give you both numbers and let you decide.

Why is my sprinkler pressure so low?

Low pressure across every zone usually means a main line leak, a partially closed shutoff or backflow valve, or too many heads on one zone. Low pressure in just one zone points to a lateral line leak or clogged heads. Either way, it is diagnosable in a single visit.
