Irrigation callouts: finding the fault faster

An irrigation system hides almost all of itself. The customer sees a dry patch or a puddle, and both are symptoms a long way from the cause.

That makes the diagnosis most of the job, and the diagnosis starts before anybody leaves the yard.

Three questions narrow it before the visit

1. Which zones fail, since one zone points at a valve or a wire and all zones point at supply or the controller.
2. What changed recently, because a new fence, a landscaping job or a trench explains most sudden faults.
3. What the controller shows, as a fault light or an error narrows the search considerably.

Those answers turn a search across a whole garden into a search in one area. That is usually the difference between an hour and half a day.

Stock the parts that actually fail

Solenoids, diaphragms, wire connectors, poly fittings and sprinkler bodies cover most domestic faults.

A month of recording every part fitted produces that list for a given area. Our guide to van stock covers the same habit in a trade with the same problem.

Water pressure explains more faults than parts do

A system designed for one pressure behaves badly at another, and a mains upgrade or a new pump changes it without anybody connecting the two.

Measuring pressure at the start of a callout takes minutes and occasionally explains everything, including faults somebody has chased for months.

Wire faults need a method, not a search

A buried wire fault can sit anywhere along a run, and digging at random finds it only by luck.

Testing at the controller, then at each valve, narrows the run before any spade touches the lawn. That order saves a garden as much as it saves time.

Controllers get replaced more often than repaired

A failed controller on an older system is usually cheaper to replace than to diagnose, and the replacement brings scheduling the customer will actually use.

Saying that plainly, with both prices, respects the customer more than an hour spent proving the old one is dead.

Seasonal checks prevent most emergency calls

A visit before the dry season finds the faults that would otherwise appear during the first hot week, when everybody rings at once.

Selling that check as a repeating job flattens the year and catches the problems while they are small.

Water restrictions decide what a system may do

Councils and water authorities change the permitted days and hours, and a controller programmed two summers ago is often outside the current rules.

A service visit that resets the schedule to the local rules protects the customer from a fine. It also gives the visit a second purpose.

Record the system, not just the visit

Zone layout, valve locations, controller model and wire colours all matter on the next visit, which may be two years away.

Holding that against the property means the second visit starts where the first one finished, rather than from nothing.

Leaks waste water quietly and expensively

A cracked lateral under a lawn can run for months without a visible symptom, and the customer meets it as a water bill.

Mentioning that possibility when a bill looks wrong turns a vague complaint into a job with a clear purpose.

What to change first

• The booking call asks which zones, what changed and what the controller shows
• A month of parts fitted sets the van's stocking list
• Pressure gets measured at the start of every callout
• Wire faults follow a test sequence before anybody digs
• A failed controller gets both prices, repair and replacement
• A pre season check sells as a repeating job
• Zone layout and valve locations record against the property
