From the meter to the houseCaliche makes digging slowClark County and valley cities
The water service line runs underground from the meter to the house, and it is the homeowner's side of the system. The Southern Nevada Water Authority says a meter indicator that keeps moving with every tap off usually means an underground leak.

A water line repair fixes the buried supply line between the meter and the house. Signs include a wet patch in the yard, falling pressure and a meter indicator that moves with every tap off. Digging here is slowed by caliche, a hard calcium carbonate layer under the soil.
This page covers water line repair across the Las Vegas Valley. If you are not sure this is the right service, start from every service we cover.
A service line leak shows up outside first, if it shows up at all. Desert soil takes a great deal of water before anything reaches the surface.
The meter is the dividing line. Water moving there with the house shut down is the clearest signal a homeowner can read without any tools at all.
The evidence sits outside the house or at the meter, not inside a wall. Everything indoors works, but the meter keeps turning and pressure is down everywhere at once. That combination points at the buried run between the meter and the house.
This page is about the pressurized supply line outside the house. Sewage backing up is the waste side, and that is sewer Line Repair and Replacement for Las Vegas homes. A leak inside the walls belongs with pipe repair across Clark County, and one under the concrete floor is slab leak repair service in Southern Nevada. If nothing has been located yet, start at leak Detection in Clark County, NV.
The work runs from the meter to the point where the line enters the house. What happens above ground, across the yard and the driveway, is as much of the job as the pipe itself.
| What is included | What that means |
|---|---|
| Meter test and pressure reading | The house is shut down and the meter is watched, which separates a service line leak from a fixture leak inside the house. |
| Locating the run | The line is traced from the meter to the entry point before digging, because the path is rarely the straight line people assume. |
| Excavation through caliche | Digging in the valley often means breaking through a calcium carbonate layer as hard as concrete, which adds both time and equipment. |
| Spot repair or full replacement | One clean break in a sound line can be cut out and coupled, while a line with several failures is usually replaced end to end. |
| Restoration of the surface | Landscape, gravel, pavers or concrete over the trench are dealt with, and what gets restored is written down before digging starts. |
| Pressure test and startup | The repaired line is pressurized and watched before backfill, so a bad joint is found while the trench is still open. |
The order protects your yard, because the last thing anyone wants is the wrong trench.
You turn off every fixture and appliance. The plumber times the flow indicator, which shows whether water is moving with nothing running anywhere.
First thing on siteYou point out irrigation, low voltage lighting and anything buried you know about. The plumber traces the service run and marks its path above ground.
Before any excavationYou approve the trench path and the restoration scope in writing. The plumber explains what comes up out of the ground and what goes back.
Before the first cut in the groundYou stay clear of the trench while work is underway. The repair is made, the line is pressurized and watched before any soil goes back over it.
Once the trench path is approvedThe price is final once the line is traced and the trench path is agreed, because length and surface decide most of the cost.
We will be straight about a gap here. Published cost guides carry solid ranges for leak detection and for interior work. We did not find a Las Vegas specific published range for replacing a buried water service line.
So this page shows the detection and diagnostic ranges with their sources, and stops there. Putting up a number we cannot source would be the opposite of what this site is for.
A plumber comes out, runs the meter test, traces the line and measures the run from the meter to the house. The length, the depth and whatever covers the trench are what make the price.
You get the number in writing before the ground is opened, along with what will be restored and what will not. If caliche or an unmarked utility changes the dig, the revision is priced and approved before work goes on.
| Job | Typical Las Vegas range | What moves the number |
|---|---|---|
| Leak detection | $125 to $400 | Repairing the pipe once it is found runs about $150 to $350 more. Las Vegas contractors commonly publish $200 to $600 for detection. |
| Service call or diagnostic fee | $75 to $150 | The broader trade range runs about $50 to $200. Emergency and after hours dispatch is higher, commonly $150 to $350 or more. |
| Pressure regulator replacement | $200 to $700 | Average around $400. |

One clean break in a sound line is worth a spot repair, while a line patched twice already is cheaper to replace outright.
Published guides put a plumbing service call or diagnostic fee at about $75 to $150, with a broader trade range of $50 to $200. Leak detection as a separate service is published at $125 to $400, and Las Vegas contractors commonly publish $200 to $600.
On this job the SNWA voucher matters more than the credit rule, because it can cover the diagnostic outright for a single family home. Read the voucher terms first, then ask what the fee is and whether it is credited.

These pictures show the two parts of the system this page keeps returning to. Both are illustrations of the conditions, drawn to show where the diagnosis actually happens.
The meter is where this diagnosis starts and often where it ends. With every tap in the house off, a flow indicator that keeps moving means water is leaving the system. SNWA points at the buried run between the shutoff and the meter.
Low pressure everywhere does not always mean a buried leak. A failing pressure regulator produces the same complaint at every fixture in the house. Checking it is quick, and published replacement ranges run $200 to $700.
The meter box and the regulator are drawn here, not photographed on a job. Real photographs take their place when there are releases that allow it.
On the customer side of the meter, yes. The sewer lateral works the same way in the Clark County Water Reclamation District area. The utility maintains its own side. Confirm the exact boundary with your water provider before anyone digs.
No. The line gets traced and marked above ground first, so the trench follows the pipe instead of searching for it. A spot repair is a short trench at one point, and a full replacement follows the marked run.
A buried leak does not hold still, and you pay for every gallon of it. The EPA puts average household leak losses above 9,300 gallons a year, and a service line leak runs well past that figure.
Caliche. Valley soil contains a calcium carbonate layer about as hard as concrete. It is a main reason homes here are built on slabs rather than basements. Breaking through it takes equipment, not a shovel.
Ask for that in writing before the dig, from anyone who bids the job. Soil and gravel are usually restored, while grass, mature plants, pavers and concrete are often quoted separately. What is included should be on the page you sign.
We cover water line repair in every part of the valley listed below. Each area page names the office that issues the plumbing permit there and who owns the sewer line at the curb, because both genuinely differ from one city to the next.
Say it is about this when you call and you skip the sorting.
We are a service area business. We come to you, so there is no counter to visit and no street address on this page. The number above is the fastest way in.
About a minute of detail changes what we can tell you on the call.
Turn off every tap and appliance that uses water, then watch the flow indicator on your meter. If it keeps moving, SNWA says the leak is most likely underground between the shutoff valve and the meter. A wet patch in the yard confirms it.
A greener patch of grass, a soft spot in gravel or standing water in the meter box all point the same direction. So does low pressure at every fixture at once.
The buried line on the house side of the meter is generally the property owner's. The same rule applies to the sewer lateral in the Clark County Water Reclamation District area. There, the line from the house to the main in the street belongs to the owner.
Confirm the precise boundary with your water provider before work begins. Meter placement varies, and the answer changes what you are actually paying for.
We did not find a published Las Vegas specific range for replacing a buried service line, so this page does not print one. Published guides do put leak detection at $125 to $400 and a diagnostic service call at $75 to $150.
The real drivers are length, depth and what covers the trench. Get the number in writing after the line is traced and before the ground is opened.
Caliche. It is a calcium carbonate layer in the desert soil, about as hard as concrete, and it sits under much of the valley. It is a main reason homes here are built on slabs instead of basements. That one fact shapes most excavation bids.
In practice it means excavation needs breaking equipment rather than hand digging. That shows up as hours on a bid, which is why two quotes for the same length can differ.
Sometimes, using pull through or bore methods that need a pit at each end instead of an open trench. Whether it works depends on the soil, the depth, the length of the run and what sits above the line. Caliche limits it in parts of the valley.
The comparison is total cost, not method. A trenchless run costs more per foot and less in restoration, so the right answer depends on what covers the line.
It can. The Southern Nevada Water Authority offers single family homeowners up to $250 toward a leak diagnostic visit or the first two hours of leak repair. It is one per property per calendar year, through a participating Water Smart Plumber.
Read the current terms on the SNWA rebate page before booking anything. We make no claim about our own standing in that program, and you should ask any plumber to show you theirs.
If the leak was the cause, yes. A leaking service line bleeds pressure before the water ever reaches the house. If the pressure was low before the leak started, the regulator or corroded interior pipe is the more likely cause.
Published guides put pressure regulator replacement at $200 to $700. That check is quick and worth doing before anyone assumes the buried line is the whole story.
