Where Is That Leak? Las Vegas Leak Detection Guide
Follow the clues from unusual water use to a located leak, a written repair plan and the restoration work that follows.

In this guide
THE TAKEAWAY
Detection should narrow the location and explain uncertainty before walls or floors are opened. Agree on what the report includes and who carries the findings into the repair.
Collect clues before choosing an access point
Collect the clues without assuming where the water is coming from: a utility alert, unexplained use, a damp cabinet, staining, a warm floor area or a sound when fixtures are off. Note whether the symptom appears during rain, irrigation or use of a particular fixture. This helps distinguish water-supply leaks from drainage, roof or equipment-related water. Ask for a detection scope before authorizing walls or flooring to be opened, and clarify how certain the location can be before destructive access.
A CLOSER LOOK
A water-use alert is a clue, not a leak location
For an LVVWD alert, save the message and compare the timing with irrigation, pool filling or a change in household use. Give that timeline to the plumber. An unusual-use notification does not tell you which pipe to replace.
Ask whether the investigation distinguishes the house supply from irrigation and other branches. Before destructive access, request the marked area and the next decision if the first opening does not reveal the leak.
- Save the alert and relevant dates.
- List scheduled water uses that could explain the pattern.
- Request findings before approving finish removal.
LVVWD uses meter information to notify customers about unusually high use. [1]
Compare your options
| Option | When to discuss it | What to clarify |
|---|---|---|
| Investigate an accessible connection | The evidence points to a fixture, valve or visible pipe. | Ask whether the visit includes the repair or only detection. |
| Locate concealed supply leakage | The source may be under a slab, behind a wall or outside. | Request the method, confidence and proposed access location. |
| Refer to another system specialist | Rainwater, pool plumbing or drainage may be responsible. | Ask what evidence supports that direction before paying for unrelated work. |
What the detection report should contain
The proposal should identify the suspected system, inspection method, access limitations and the report you will receive. Ask whether the technician will mark the location and explain any uncertainty. Detection and repair may be performed by different companies; establish who coordinates the handoff and whether the repair contractor accepts the findings.
Before opening surfaces, ask for the access size, protection of finishes, repair options and restoration responsibility. Include a written approval step if the initial opening does not locate the problem.

What affects the price
Detection can be a separate service even when no repair is performed. Ask what the fee includes, how long the investigation continues, and what happens if the source is not found. Compare repair alternatives only after the affected line is identified.
A reroute, local repair and larger repipe can have very different disruption and finish costs. Insurance coverage or utility adjustments require separate review; a detection report is evidence, not a promise of reimbursement.
Questions to ask before approving work
- Which system are you investigating?
- What will the detection report establish, and what may remain uncertain?
- Does this quote include repair or only location?
- Who approves and restores destructive access?
After the visit: checks, records and upkeep
Keep the report, photographs, marked location and repair test results. Monitor the original symptom after the work and ask when a return visit is appropriate. If materials were wet, clarify who evaluates drying or damaged finishes rather than assuming the plumbing repair completes restoration.
Update the contractor if water use remains unusual. Keep a record of dates and readings so an intermittent problem can be reassessed with more than a memory of the first visit.
Common questions
Can leak detection guarantee the exact spot before opening anything?
Ask about the method’s limits and the confidence of the finding. The agreement should explain what happens if the first access point does not expose the source.
Who should I call if the stain only appears during rain?
Describe that pattern. It may call for roof or exterior-water investigation rather than supply-pipe detection.
Find local plumbing companies
Compare the full company selection, then confirm the exact work and your address directly. Specific services and workmanship are not verified by broader project records.

LVVWD’s unusual-use notifications recommend checking the property for possible leaks or malfunction; an alert is a starting clue. [1]

How this guide is put together
These are AI-assisted editorial guides for homeowners, built around published sources and practical questions to ask. This update checks the added source-backed context; it is not a licensed trade professional’s technical review or an inspection of your home. Earlier references retain their individual access dates below their citations.
