Irrigation & Sprinkler Leak Detection & Repair in Reno, NV
More watering won’t fix a leaking irrigation system.
When one sprinkler zone struggles while another leaves the ground soaked, increasing the run time can waste more water without solving the problem. Our irrigation and sprinkler leak detection in Reno focuses on identifying where water escapes and which part of the system needs attention.
We check how the affected zones operate, looking at sprinkler heads, valve connections and buried irrigation lines. Whether water appears during a watering cycle or continues collecting after the system stops, that timing helps guide the investigation.
Once the fault is identified, Leak Detection Reno explains the repair needed and any access required. The aim is to correct the water loss and check the affected zone’s operation before you return to your usual watering schedule.

The Basics
Irrigation Leaks in Reno, NV — the Water Waste You Never See
An irrigation system is a second plumbing system for your yard: a pressurized main from the backflow device, zone valves, and miles of lateral lines feeding sprinkler heads, all buried inches to feet below grade. When a lateral cracks or a fitting lets go, the water does not announce itself — it surfaces as a soggy strip, a sunken spot, a head that mists instead of sprays, or a zone that has quietly lost pressure. Because the damage is underground and the schedule is intermittent, an irrigation leak can run for an entire season before someone connects the soggy corner of the lawn to the number on the TMWA bill.
Reno makes irrigation leaks uniquely easy to miss — and uniquely expensive. TMWA's assigned-day watering schedule (even addresses on Tuesdays, Thursdays, and Saturdays; odd addresses on Wednesdays, Fridays, and Sundays; Mondays are the system-wide rest day) means a hidden leak fires on a predictable rhythm that blends into your normal usage pattern. Our short but intense irrigation season compresses the damage into the months your bill is highest. And every winter, freeze-thaw works on shallow lines — especially systems that were never blown out — splitting fittings and laterals that fail the moment the system is charged in spring.
Our approach is systematic, not guesswork. We map the zones, isolate them one at a time, and watch pressure — the failing zone identifies itself. Acoustic listening and, where needed, tracer gas pinpoint the exact break from the surface, so any opening is one small, marked dig instead of a exploratory trench across the yard. Most head, fitting, and lateral repairs are completed the same visit at a flat rate quoted before we start, and every job ships with documentation that supports a TMWA leak adjustment on your water bill.
Sprinkler Leak Warning Signs
Signs of an Underground Sprinkler Leak in Your Reno Yard
Irrigation leaks leave a trail — you just have to know it is a trail and not normal watering. Any one of these signs justifies a zone test.
Soggy spots between watering days
Mushy ground or standing water on a day the system has not run — or near valve boxes and head clusters hours after a cycle ends — is leak water, not irrigation.
A zone that lost its punch
Heads that mist, dribble, or fail to pop up while other zones run strong — a classic pressure signature of a lateral line leaking before the heads.
One suspiciously green patch
A strip of lawn that outgrows everything around it is being fed from below. Fertilizer and seed do not explain a single perfectly linear stripe.
Bubbling or sinking ground mid-cycle
Water bubbling up at a point, or ground that has visibly sunken along the line's path, marks the failure — the soil is literally being washed away.
A TMWA bill that creeps up in season
Usage climbing month over month on the same watering schedule is the bill confirming what the yard is hinting — water is leaving the system underground.
A zone that never quite finishes
Valve weeping after shutdown, a zone that takes forever to pressurize, or heads that stay wet between cycles point to a valve or lateral losing water in place.

How We Find and Fix Sprinkler Leaks in Reno, NV
Four steps — isolate, pinpoint, repair, verify — and the shovel only touches the one spot the evidence marks.
- Step 1
System walk & zone mapping
Controller, backflow device, valve boxes, head layout — we map how your zones actually run before testing, so the results mean something.
- Step 2
Zone-by-zone pressure isolation
Zones are valved off and run one at a time while we watch pressure and flow — the failing zone identifies itself instead of us guessing.
- Step 3
Acoustic pinpoint of the break
Ground microphones track the leak's hiss along the failing lateral or main to its exact point — including depth — before any ground is opened.
- Step 4
Flat-rate repair & verification
The head, fitting, or line section is repaired at a quoted flat rate, the zone is re-run and pressure-checked, and you get documentation for a TMWA leak adjustment.
Transparent Pricing
What Irrigation Leak Detection Costs in Reno, NV
Flat rates, confirmed before we begin — the same published pricing whether the leak is in a flower bed or under the far corner of the lawn.
| Service | Typical Reno Price | What's Included |
|---|---|---|
| Irrigation leak testing visit | $195–$395 flat-rate | Zone mapping, zone-by-zone pressure isolation, acoustic pinpoint, marked location, photos, written report |
| Head & fitting repairs | Flat-rate, quoted on-site | Sprinkler head replacement, lateral fittings, riser repairs — most completed the same visit |
| Lateral line section repair | Flat-rate, quoted on-site | One marked opening, pipe section replaced, flushed and pressure-tested before backfill |
| Main line & valve repairs | Quoted after testing | Pressurized main leaks and valve body failures — repair plan and quote before work begins |
Money-back note: TMWA grants leak adjustments for documented, repaired leaks — and its smart-meter portal can even flag abnormal use with leak alerts. Our written report, photos, and marked location are formatted for exactly that claim, so the water you lost does not have to be money you lost too.

Irrigation Repair Options — Quoted Before We Dig
The right fix depends on what the zone test shows. You will see every viable option with flat-rate pricing before the first shovel of soil moves.
Head & fitting repair
Cracked heads, weeping risers, failed swing joints and fittings — the most common repairs, usually finished the same visit and verified zone-by-zone.
Lateral section replacement
When a lateral run is cracked, crushed, or root-damaged, the marked section is replaced — one opening at the mark, flushed, tested, backfilled.
Main line & valve rebuild
Pressurized main failures and valve body leaks get a full repair plan — including a backflow device check — so the whole system holds pressure again.
The Equipment
The Equipment That Finds Irrigation Leaks Without Trenches
Four technologies, deployed in sequence — the dig happens only after the location is confirmed.
Zone Pressure Isolation
Valving zones one at a time turns a yard-wide mystery into a single failing line — the fastest way to make the system point at its own problem.
Acoustic Ground Microphones
Amplify the hiss of pressurized water escaping the lateral — tracked along the run until the loudest point marks the break within inches.
Tracer Gas Detection
A safe hydrogen-nitrogen mix pushed through the line escapes at the break and rises through soil — finds the silent leaks acoustics miss.
Moisture & Flow Checks
Meter movement with the system charged, plus surface moisture mapping between cycles — objective evidence of where water is going.
Understanding Local Leaks
Why Sprinkler Systems Leak in Reno, NV
The Truckee Meadows is hard on irrigation. Four local forces account for most of the failures our zone tests find.
Freeze damage & missed blow-outs
Water left in shallow lines splits fittings and laterals over winter — the reason so many Reno systems fail at spring start-up, not mid-summer.
Rocky foothill soils
Sierra-foothill gravel abrades pipe at every contact point, and rocky backfill concentrates stress on fittings — leaks start where the rock touches.
Hard-water scale in valves & heads
Mineral-heavy water builds scale that stiffens seals and diaphragms — valves weep, heads stick open, and slow leaks run cycle after cycle.
High-season water rates
The leak runs hardest exactly when your TMWA bill is most rate-sensitive — a pinhole on one zone can waste hundreds of gallons per watering day.
