What Does a Professional Irrigation Inspection Include in San Diego?

AN IRRIGATION INSPECTION SHOULD LOOK AT THE ENTIRE SYSTEM

When an irrigation system develops a problem, the most visible symptom is not always the actual cause.

A brown section of lawn may appear to need more watering, but the real problem could be poor sprinkler coverage.

Standing water may look like overwatering, but a leaking valve may be allowing water to continue flowing after the irrigation cycle ends.

A sudden increase in a water bill may occur without any obvious water at the surface because the leak is underground.

That is why a professional irrigation inspection should evaluate the system as a whole rather than simply replacing the first broken component that can be seen.

Homeowners who want to better understand how irrigation, water conservation, controllers, drip systems, and landscape conditions work together can also review our Complete Guide to Smart Irrigation & Water Conservation in San Diego.

START WITH THE IRRIGATION CONTROLLER

The controller determines when each irrigation zone operates and for how long.

An inspection should confirm that the controller is functioning correctly and that the program still matches the landscape.

Items that may be reviewed include:

Watering days.

Start times.

Station run times.

Seasonal adjustment.

Controller date and time.

Rain or weather sensors.

Smart-controller settings.

Whether multiple programs are operating unintentionally.

A perfectly functional irrigation system can still waste water when the controller has been programmed incorrectly.

OPERATE EVERY IRRIGATION ZONE

Each zone should be operated individually.

This allows the technician to observe the actual performance of the system rather than relying only on what the homeowner has noticed.

During operation, potential problems may become visible immediately.

These can include:

Broken sprinkler heads.

Sprinklers that do not rise correctly.

Sprinklers that remain up after operation.

Weak spray patterns.

Clogged nozzles.

Poor coverage.

Overspray.

Water hitting walls or fences.

Zones that fail to turn on.

Zones that will not shut off.

Low pressure.

Excessive pressure.

Unexpected water appearing in another part of the property.

Operating every zone is one of the most important parts of an irrigation evaluation.

INSPECT THE IRRIGATION VALVES

Valves control the flow of water to individual irrigation zones.

When a valve begins failing, homeowners may notice a zone that does not turn on, a zone that will not shut off, low pressure, constant water around the valve box, or water continuing to seep from sprinkler heads after the system stops.

Potential valve issues can involve:

Solenoids.

Diaphragms.

Wiring.

Connections.

Debris inside the valve.

Physical damage.

Age.

Pressure conditions.

An irrigation valve problem should be diagnosed rather than assuming the complete valve assembly needs replacement.

CHECK SPRINKLER COVERAGE

A sprinkler can be operating and still fail to water correctly.

Heads may become tilted.

Nozzles clog.

Plants grow into the spray pattern.

Pressure changes.

One sprinkler may have been replaced with a nozzle that does not match surrounding heads.

Coverage should be evaluated based on how water reaches the intended landscape—not simply whether water comes out of the sprinkler.

Poor coverage often creates dry areas that homeowners attempt to correct by dramatically increasing irrigation time.

That can create overwatering elsewhere while the original dry area remains.

INSPECT DRIP IRRIGATION

Drip irrigation is highly effective for many San Diego landscapes, but it should still be inspected regularly.

Potential drip irrigation problems include:

Disconnected tubing.

Damaged fittings.

Clogged emitters.

Missing emitters.

Exposed tubing.

Leaks.

Improper pressure.

Plants that have outgrown their original irrigation layout.

Drip lines buried under mulch or plant material can make problems difficult to see.

A healthy-looking area next to a struggling plant may indicate that water is not being distributed evenly.

If an older spray system is watering planting beds inefficiently, it may also be worth evaluating whether Drip Irrigation Installation & Sprinkler Conversion is appropriate for that portion of the landscape.

LOOK FOR HIDDEN LEAKS

Not every irrigation leak creates a dramatic puddle.

Some leaks remain underground.

Possible warning signs include:

Unusually wet soil.

Mushy lawn areas.

Water appearing when the irrigation system is off.

Low system pressure.

Unexplained increases in water usage.

A section of landscaping growing significantly faster than surrounding areas.

Erosion.

Water collecting inside valve boxes.

Finding a hidden leak sometimes requires narrowing down which portion of the irrigation system is losing water before excavation begins.

EVALUATE WATER PRESSURE

Pressure affects how the entire irrigation system performs.

Too little pressure can prevent sprinkler heads from operating correctly and reduce coverage.

Too much pressure can create misting, premature component wear, excessive runoff, and inefficient watering.

Pressure conditions may also reveal problems that are not visible when the system is off.

The objective is to deliver water efficiently—not simply force more water through the system.

LOOK AT THE LANDSCAPE, NOT JUST THE IRRIGATION

An irrigation system should always be evaluated together with the landscape it serves.

Important observations may include:

Plant stress.

Lawn condition.

Sun exposure.

Slopes.

Soil conditions.

Drainage.

Mature plant size.

Different plant-water requirements.

Recent landscape changes.

New construction.

Tree-root growth.

An irrigation system that was appropriate ten years ago may no longer match the property today.

Plants mature and landscapes change.

The irrigation system should change with them.

Regular Landscape Maintenance Service in San Diego can also help identify irrigation, plant-health, and water-distribution concerns before small issues develop into larger problems.

REVIEW IRRIGATION AROUND HARDSCAPE AND STRUCTURES

Overspray and leaks can affect more than plants.

Water repeatedly reaching fences, walls, patios, walkways, masonry, retaining walls, or the exterior of a home may cause staining, deterioration, algae growth, erosion, or other undesirable conditions.

Sprinkler direction and coverage should therefore be evaluated in relation to surrounding improvements.

A properly adjusted system puts water where the landscape needs it and minimizes water where it does not belong.

DETERMINE WHETHER THE SYSTEM NEEDS REPAIR, ADJUSTMENT OR AN UPGRADE

Not every irrigation inspection should end with a complete replacement recommendation.

Some properties need only targeted repairs.

Others benefit from modernization.

Depending on the system, recommendations may include:

Replacing damaged sprinkler heads.

Repairing irrigation valves.

Correcting damaged pipes or fittings.

Adjusting nozzle selection.

Repairing drip irrigation.

Improving pressure regulation.

Reprogramming the controller.

Installing a smart controller.

Converting appropriate spray areas to drip irrigation.

Separating plants with very different water requirements.

Adding or modifying irrigation zones.

The best recommendation should respond to the condition of the actual property.

HOW OFTEN SHOULD AN IRRIGATION SYSTEM BE INSPECTED?

There is no single schedule that works for every property.

Landscapes with extensive irrigation, large lawns, mature gardens, slopes, multiple drip zones, or complicated controllers may benefit from more frequent observation.

At minimum, homeowners should pay attention when seasons change, landscaping is modified, a water bill changes unexpectedly, plants begin showing stress, or unusual wet areas appear.

Regular landscape maintenance also creates opportunities to identify irrigation concerns before they become larger problems.

FREQUENTLY ASKED QUESTIONS

Can an irrigation leak happen without visible water?

Yes. Underground irrigation leaks may remain below the surface or drain into surrounding soil before they become obvious.

Why does my sprinkler zone stay on?

Potential causes can include a valve or solenoid problem, debris inside the valve, wiring or controller issues, or other system conditions that should be diagnosed.

Why does one area of my lawn stay dry even though the sprinklers run?

Poor coverage, a clogged or incorrect nozzle, low pressure, a damaged sprinkler, spacing issues, or changing landscape conditions can all contribute.

Can a professional inspection help lower water use?

Identifying leaks, correcting overspray, improving controller programming, adjusting irrigation coverage, and updating inefficient components may reduce unnecessary water use.
