Leak Detection in Florence, AZ
Unexpected usage, recurring moisture, meter flow, sound, or a temperature difference can justify leak detection. Town water customers also have WaterSmart hourly-usage and possible-leak alerts.
Finding a Hidden Water Leak in Florence, AZ
A hidden leak may first appear as unexpected water use, recurring moisture, a meter or usage alert, sound, pressure changes, or a temperature difference. Climate alone does not tell us whether a leak exists or where it is.
Desert Vale Plumbing uses a diagnose-first process to confirm water loss and narrow the likely source before recommending access or repair.
Signs of a Hidden Plumbing Leak
Q: How can I tell if I have a hidden water leak? Watch for an unexplained rise in your water bill, a water meter dial that keeps moving with every fixture in the house turned off, warm or damp spots on flooring, and stains or soft drywall on walls or ceilings. Any one of these on its own is worth investigating; more than one together is a strong signal of an active leak.
The signs of a hidden leak vary depending on whether the leak is in a wall, under the slab, or in an underground supply line. Below are the most common indicators by location.
Signs of a Slab or Underground Leak
- An unexplained increase in your water bill with no change in household water use
- A warm spot on the floor (often a sign of a hot water line leak under the slab)
- The sound of running water when all fixtures are off
- Cracks appearing in flooring or baseboards pulling away from the wall
- A damp or unusually green patch on the lawn, even in areas not actively irrigated
- Mildew or a musty smell in a room with no obvious moisture source
Signs of a Wall or Ceiling Leak
- A visible stain, discoloration, or bubbling on a wall or ceiling
- Peeling paint or wallpaper in one localized area
- Soft, spongy, or bulging drywall
- A faint but persistent musty odor near a bathroom or kitchen wall
- Sound of dripping or trickling water inside a wall cavity
Why Is My Water Bill Suddenly High?
Q: Why is my water bill suddenly high? A sudden, unexplained increase in your water bill — without a corresponding increase in household water use — is one of the most reliable early indicators of a hidden leak. It can point to a leak in a supply line, a running toilet, an underground leak between the meter and the house, or (less often) an irrigation system issue.
If your bill jumps and you haven’t changed your water habits, the water meter test below is the fastest way to narrow down whether the source is inside the home, underground, or on the irrigation side.
How to Use Your Water Meter to Check for a Leak
For a property with a water meter, stop intentional water use and observe whether the meter continues to register flow. Also rule out common sources such as toilets, irrigation, appliance connections, hose bibs, and other water-using equipment.
For Town of Florence water customers, the WaterSmart portal provides hourly usage information and can issue possible leak alerts. That is useful for identifying abnormal consumption, but it does not locate the physical leak.
If the address is served by EPCOR rather than the Town, use the provider’s meter/account guidance for that property.
How Professional Leak Detection Works
Q: Can a plumber find a leak without cutting into walls or digging up the yard? In many cases, yes. Acoustic listening equipment, moisture meters, and thermal imaging can narrow down a leak’s location without cutting or digging first. These methods don’t work in every situation, and a plumber may still need to open a small access point to confirm and repair the leak once it’s located.
Desert Vale Plumbing uses non-invasive and non-destructive detection methods as the first step, so that any cutting, digging, or tunneling that follows is targeted rather than exploratory.
Detection Methods We Use
Acoustic leak detection. Pressurized water escaping a pipe creates a distinct sound. Acoustic sensors and listening devices amplify that sound through slab, soil, or wall material, helping narrow down the leak’s general location before any invasive work happens.
Moisture meters. These measure moisture content in drywall, flooring, and other building materials, helping confirm whether a suspected wet area is actively leaking and how far the moisture has traveled from the source.
Thermal imaging. A thermal camera reads surface temperature differences. A hot water line leak under a slab, for example, often shows up as a warm zone on the thermal image even when the surface itself looks dry — which is especially useful in Florence’s climate, where visible surface moisture disappears quickly.
Pressure testing. Isolating sections of the plumbing system and testing for pressure loss helps confirm whether a leak exists in a given line and can help narrow down which section of the system is affected.
Leak Location vs. Leak Repair
Finding a leak and fixing it are two separate steps, and it’s worth understanding the difference before repair work starts.
| Step | What it involves | What it tells you |
|---|---|---|
| Leak detection | Acoustic, moisture, thermal, and pressure testing methods used to narrow down the leak’s location | Where the leak is likely located and how significant it appears to be |
| Leak confirmation | A small, targeted access point (if needed) to visually confirm the leak’s exact location | Confirms the leak location before repair work begins |
| Repair | Spot repair, pipe section replacement, or in some cases rerouting the line | Resolves the leak based on its location, pipe material, and severity |
Once a leak is located and confirmed, your plumber should walk you through the repair options for your specific situation — including whether a spot repair, a section replacement, or rerouting the line makes more sense — before any repair work begins.
Wall and Ceiling Leaks
A leak inside a wall or ceiling cavity is often first noticed as a stain, a soft spot, or a musty smell rather than visible water. These leaks commonly originate at a supply line connection, a fitting, or a section of pipe with corrosion damage (more common in older copper lines) or a compromised fitting in PEX systems.
Because wall cavities are enclosed, acoustic detection and moisture meters are typically used together — the acoustic sensor helps narrow the general area, and the moisture meter helps confirm how far water has traveled through the drywall or framing. This combination usually allows for a targeted access point rather than opening an entire wall section.
Underground and Slab Leaks
A suspected underground or slab leak should be confirmed from meter/usage behavior, pressure or isolation testing, plumbing layout, and targeted leak-detection evidence.
A warm floor area, damp spot, or wet yard can be a clue but does not prove a below-slab line failure. Repair options should follow the confirmed line location, condition, and access.
What Happens After a Leak Is Located
Once detection confirms where a leak is, the next conversation is about repair options. Depending on the leak’s location, pipe material, and severity, that may mean a spot repair, replacing a section of pipe, or rerouting the line to avoid the affected area entirely. Your plumber should explain the options relevant to your situation so you can make an informed decision — leak detection and repair scope should always be discussed together before work begins.
If a leak has caused visible water damage, active flooding, or you smell gas near a fixture or line, treat it as an emergency: shut off the water at the main if it’s safe to do so, and call for emergency plumbing service rather than waiting.
Cost of Leak Detection
Q: How much does leak detection cost? Leak detection cost depends on the type of leak, how accessible the area is, and which detection methods are needed — there isn’t a single flat number that applies to every job. The most reliable way to get an accurate cost for your specific situation is to have a plumber assess the symptoms and confirm what detection approach is needed.
Because every property and leak is different, Pricing depends on the diagnosis and scope of work.) so we can talk through what detection approach fits your situation.
Preventing Future Leaks
Not every leak can be prevented. Useful monitoring includes reviewing water-use patterns, using the WaterSmart portal when the property is a Town of Florence water customer, checking accessible fixture and appliance connections, and keeping irrigation troubleshooting separate from household plumbing.
Recurring moisture, meter flow, or unexplained water use deserves diagnosis rather than assumptions about climate or property type.
Leak Detection Across the East Valley and Pinal County
Desert Vale Plumbing provides leak detection in Florence and throughout its published service area, including Queen Creek, San Tan Valley, Gilbert, Chandler, Mesa, Apache Junction, Gold Canyon, Sun Lakes, and Tempe.
For Florence, utility/provider context should be confirmed by address before making assumptions about meter data or public-side responsibility.
Provider boundaries matter before diagnosis.
The Town of Florence Utilities Department says its water service area extends east of Felix Road, while EPCOR serves the area to the west. The Town currently supplies potable demand from groundwater wells and operates North and South wastewater treatment facilities.
Leak-monitoring note: Town of Florence water customers can use the WaterSmart portal to review hourly water use and receive possible leak alerts. That is a useful screening tool, but it does not identify the physical leak location.

Common questions about this service.
Does leak detection require opening walls or digging up the yard?
Not always. Acoustic, moisture, and thermal detection methods are used first to narrow down a leak’s location non-invasively. A small, targeted access point may still be needed to confirm the exact spot before repair, but this is far more limited than exploratory cutting or digging.
What are the signs of a leak behind a wall?
Common signs include a visible stain or discoloration, peeling paint or wallpaper, soft or bulging drywall, a musty smell, and sometimes the sound of water inside the wall cavity. Any of these near a bathroom, kitchen, or laundry wall is worth having checked.
Can a water meter show a hidden leak in Florence?
Yes. Checking your water meter’s leak indicator with all fixtures off is one of the fastest ways to confirm whether water is moving somewhere in your system, even before you can see or hear any evidence of a leak.
What causes an unexplained high water bill?
A high water bill with no change in household water use is can caused by a hidden leak — in a supply line, underground between the meter and the house, under the slab, or occasionally a running toilet. An irrigation system issue can also cause it, which is why confirming the source matters before assuming it’s a plumbing leak.
Who should I call for an unexplained high water bill in Florence?
Once you’ve ruled out an obvious cause (a running toilet, a left-on hose bib), an unexplained high bill is a good reason to call a plumber for a water meter test and, if needed, professional leak detection. Call (888) 395-2416 to schedule service.
Is every hidden leak detectable without cutting into walls or slabs?
No. Non-invasive methods locate the large majority of leaks, but some situations still require a limited access point to confirm and repair the leak. Your plumber will explain what’s needed for your specific case rather than assuming one approach fits every leak.
