Sprinkler System Diagnostics

When something is wrong but you cannot tell what, a diagnostic finds the root cause before you spend a dollar on parts. We test the whole system, explain what we find in plain language, and give you an up-front quote.

Typical visit: 45–90 min

A sprinkler system is a chain of moving parts — a controller, low-voltage wiring, valves and solenoids, pressurized supply lines, and dozens of heads — and when one link fails, the symptom often shows up somewhere else entirely. A zone that will not turn on might be a dead solenoid, a broken wire, or a controller output that has failed, and guessing wrong means paying to replace parts that were never the problem.

Our Utah County and Salt Lake County technicians run a complete diagnostic that walks the system from the controller to the last head, isolating the true cause so you only pay to fix what actually needs fixing. Not sure what is going on at your property? Call us for a free phone estimate.

When to Book

Symptoms That Call for a Diagnostic

If your system is behaving in a way you cannot explain, a diagnostic is almost always cheaper than replacing parts one at a time. It is especially worth it when a problem affects the whole system, comes and goes, or started after a freeze, landscaping work, or an electrical event.

  • One or more zones will not turn on, or will not shut off
  • The whole system is dead even though the controller has power
  • Dry spots, flooding, or wildly uneven coverage between heads
  • A water bill or meter that keeps climbing with no visible leak
  • Pressure that is too low to pop heads up, or so high it mists
  • Problems that appeared after winter, a remodel, or new sod

What We Test

What a Full System Diagnostic Covers

We do not stop at the first thing we find. A complete diagnostic works through every subsystem so a second hidden fault does not send you right back to square one after the first repair.

  • Controller and program review — outputs, wiring terminals, and schedule
  • Electrical testing of valve solenoids and field wiring with a multimeter
  • Valve function — checking for stuck, leaking, or non-responsive valves
  • Static and running pressure plus flow to spot restrictions and leaks
  • Zone-by-zone coverage review for dry spots, overspray, and head spacing
  • Leak detection on mainlines, laterals, and drip zones

What You Get

Clear Findings, Then Your Choice

At the end of the visit you get a plain-language rundown of what we found, what is causing it, and what it will take to fix — with an up-front quote before any repair work begins. Nothing gets replaced without your say-so.

If the repair is something simple we can handle on the spot, we will often take care of it right then so you are not paying for a second trip. When it is bigger, you leave knowing exactly what the problem is and what the fix costs, with no pressure to decide on the spot.

Which Do I Need?

Repair Diagnostic vs. Start-Up / Tune-Up

These are two different visits. A repair diagnostic is the right call when you already know something is wrong — a dead zone, a leak, a controller that will not run — and you want it found and fixed. It carries the $39.99 service fee, which goes toward paying our tech for the time spent tracking the problem down.

A Start-Up or Tune-Up ($149) is a whole-system overview instead. It is the right choice when you just want peace of mind that everything is working, or you suspect there might be an issue but do not know what or where. We walk the entire system, run every zone, and flag anything that needs attention. If that walkthrough turns up a repair, you already have a technician on-site to quote it.

Homes & Commercial

Residential, HOA & Commercial Systems

Larger properties, HOAs, and commercial sites often run many zones off multiple controllers and valve boxes, which makes intermittent faults especially hard to chase down without a systematic diagnostic. We map the system, isolate the fault, and document what we find so property managers have a clear record — and we can fold ongoing checks into a commercial maintenance program.

How Repair Pricing Works

$39.99

Service fee for a repair visit

We charge a $39.99 service fee for repair visits. This lets us pay our technicians fairly for their time diagnosing and inspecting the issue — even if you choose not to move forward with us, which does not happen often. From there you get an up-front quote, and if you approve it we complete the repair on the spot whenever possible; most repairs run $250–$750. Maintenance plan members skip the service fee entirely, and all repairs are backed by a five-year parts and labor warranty on a plan.

  • $39.99 service fee covers the visit and full diagnosis
  • Up-front quote before any work begins
  • Most repairs completed the same visit if approved
  • Service fee waived for all maintenance plan members

FAQ

Common Questions

How much does a sprinkler system diagnostic cost?

We charge a $39.99 service fee for a repair visit. It covers coming out and diagnosing the issue, and it lets us pay our technicians fairly for their time even if you decide not to move forward. You then get an up-front quote, and if you approve it we complete the repair — most repairs run $250–$750. Maintenance plan members skip the service fee entirely.

Should I book a repair diagnostic or a Start-Up / Tune-Up?

Book the repair diagnostic ($39.99 service fee) when you already know something needs to be fixed. Choose the Start-Up or Tune-Up ($149) when you just want to confirm the whole system is healthy, or you suspect a problem but do not know what it is — that visit is a full overview of every zone.

How long does a diagnostic take?

Most diagnostics take 45 to 90 minutes depending on the size of the system and how many zones and controllers are involved.

Why not just replace the part that seems broken?

Because irrigation faults often show up away from their cause — a dead zone can be a solenoid, a broken wire, or a failed controller output. Testing first means you replace the right part once instead of guessing and paying for parts that were never the problem.

One zone will not turn on. Is that always the valve?

Not necessarily. It can be the solenoid, the field wiring, a controller output, or a stuck valve. That is exactly what the electrical and valve testing in a diagnostic isolates.

Do you fix the problem during the diagnostic visit?

When the fix is simple we will often handle it on the spot to save you a second trip. For larger repairs, you get a clear quote first and decide from there — nothing is replaced without your approval.
