Hearing water when no fixtures are on, or noticing warm patches on your floor? These can be classic signs of a water leak under your slab. A hidden slab leak can quietly damage floors, foundation, and finishes. In this guide, we explain the telltale signs, how to confirm a leak, and the smartest repair options for Utah County homes. If you are worried, call Eric's Plumbing & Drain Cleaning for fast detection and repair today.
What Is a Slab Leak and Why It Matters
A slab leak is a pressurized water or drain line leak that occurs beneath your home’s concrete foundation. Because the piping is buried under the slab, leaks can run for weeks before you notice a bill spike or surface damage. Left unresolved, slab leaks can undermine soil, crack concrete, and promote mold.
Two hard facts to frame the risk and the solution:
- The EPA estimates household leaks can waste nearly 10,000 gallons per home each year, and 10 percent of homes leak over 90 gallons per day. A concealed slab leak can easily exceed that.
- In Utah, plumbing work is required to be performed by licensed professionals. Our team members hold active Utah Journeyman Plumber licenses, and we back repairs with a one year warranty plus a 100 percent satisfaction guarantee.
In Utah County, many homes in Provo, Orem, and Spanish Fork sit on mineral heavy soils with seasonal temperature swings. That combination can stress lines under the slab, making fast detection critical.
Common Signs You May Have a Water Leak Under Your Slab
Not every symptom means a slab leak, but these red flags deserve immediate attention:
-
Unexpected water bill increases
- A steady climb with no change in use often points to a hidden leak. Compare your last three statements for a pattern.
-
Warm or cold spots on hard floors
- Radiant floor zones and hot water slab leaks can create a persistent warm patch. Cold patches may appear with chilled supply leaks.
-
The sound of running water when fixtures are off
- A faint hiss or gentle whoosh from the floor or walls when everything is shut hints at pressurized water escaping.
-
Damp or spongy flooring and baseboards
- Moisture may wick up through underlayment, warping laminate or cupping hardwood near interior walls.
-
Mold, mildew, or musty odors
- Persistent odor near interior walls or closets can mean moisture is trapped under the slab or in wall cavities.
-
Reduced water pressure or sporadic hot water
- Pressure drops and temperature swings occur when a line is leaking downstream of your shutoff.
-
Foundation cracks, settling, or uneven floors
- Water can erode or expand soils under the slab. New cracks or doors rubbing the floor can be a clue.
-
Visible water at slab edges or where the floor meets a wall
- Water may show at low spots, door thresholds, or garage transitions.
-
Meter test fails
- Shut off every fixture and appliance. Watch your water meter. If the leak indicator spins, you have a supply side leak.
If you see two or more of these signs in the same area of the home, schedule professional diagnostics right away.
How Pros Confirm a Slab Leak Without Guesswork
Accurate diagnosis saves you from unnecessary demolition and extra costs. Our process focuses on precision and documentation:
-
Pressure and isolation tests
- We test hot and cold lines separately, isolate branches, and pinpoint the leaking run before opening anything.
-
Acoustic and thermal detection
- Sensitive microphones and thermal imaging help locate temperature anomalies and the subtle sounds of escaping water.
-
Video camera inspections for drains and sewers
- If the issue involves a drain or sewer under the slab, we run a high definition camera to confirm the defect and its exact location, then document before and after results.
-
Tracer gas or dye testing when needed
- For complex cases or intermittent leaks, safe tracer gas or dye can expose concealed paths.
The outcome is a clear plan with photos or video. You know what is leaking, where it is, and the least invasive way to fix it.
What Causes Slab Leaks in Utah County Homes
Several local factors contribute to slab leaks in Provo, Orem, Saratoga Springs, and Spanish Fork:
- Hard water and corrosion
- The Wasatch Front is known for mineral heavy water. Over time, it can accelerate pitting in copper lines.
- Soil movement and seasonal shifts
- Freeze thaw cycles and irrigation can expand and contract soils, stressing fittings and joints under the slab.
- Construction practices in older homes
- Older copper lines laid directly on concrete can wear from micro movement. Some mid century homes lack modern sleeve protection.
- High water pressure
- Static pressure over 80 psi strains fixtures and lines. A failed PRV can turn small weaknesses into leaks.
- Vibrations and slab settling
- Traffic, nearby construction, or natural settling can fatigue elbows and solder joints.
Local insider note: homes near Hobble Creek Canyon and bench areas can experience bigger swings in soil moisture and temperature, which amplifies movement under slabs.
Risks of Delaying Slab Leak Repairs
Waiting often costs more. Here is what can happen:
- Structural damage
- Soil washout can lead to slab cracks and uneven floors that require structural remediation.
- Mold and air quality issues
- Moisture trapped under flooring and in walls grows mold. Remediation costs can outpace the plumbing repair.
- Higher utility bills
- Pressurized leaks send money down the drain every minute.
- Secondary failures
- Wet electrical, damaged cabinets, ruined finishes, and failed flooring add to the total.
Prompt action nearly always reduces the total project cost and the disruption to your home.
Repair Options Explained: Least Invasive First
Every home is different, but we tailor repairs to minimize demolition and maximize reliability.
-
Spot repair through a small access opening
- Best when the leak location is precise and accessible. We cut a small opening, repair or replace the failed section, pressure test, and restore.
-
Line reroute above the slab
- Ideal for repeated leaks or inaccessible spots under tile or cabinetry. We abandon the leaking run and install a new line through walls or attic, often using PEX or copper, then patch and paint the small access points.
-
Trenchless solutions for sewers and drains
- If your under slab issue is a drain or sewer leak, we prioritize trenchless options to protect your floors and yard:
- UV cured CIPP lining
- With our Bluelight UV system, we inspect the liner with an onboard camera before curing, then cure it rapidly with light for a strong, smooth pipe within a pipe. Pre cure inspection reduces surprises and speeds completion.
- Pipe bursting
- For collapsed or severely corroded lines, we break the old pipe while pulling a new, same diameter or larger line into place, with minimal excavation.
- UV cured CIPP lining
- If your under slab issue is a drain or sewer leak, we prioritize trenchless options to protect your floors and yard:
-
Hydro jet cleaning before lining
- We clear roots and scale with hydro jetting to prepare the pipe for a durable bond. Mainline and jetting services include short term guarantees.
These methods limit disruption to your floors, landscaping, driveway, and sidewalks while restoring full function quickly.
What Does a Slab Leak Repair Cost in Utah County
Costs vary with location, access, and the best repair path. A few drivers to consider:
- Leak location certainty
- Confirmed locations cost less to access than exploratory demolition.
- Flooring and finish type
- Tile, stone, and heated floors take more care than carpet or vinyl.
- Reroute distance and obstacles
- Multi story homes, finished basements, and long reroutes add labor.
- Condition of adjacent piping
- If additional sections show corrosion, upgrading during the repair can save future visits.
We provide set pricing after diagnostics, not open ended hourly charges. Financing is available for larger projects. Our 1 year repair warranty and 100 percent satisfaction guarantee protect your investment.
How to Check for a Slab Leak Before You Call
Simple homeowner steps can quickly separate false alarms from real concerns:
-
Meter test
- Shut off all fixtures, irrigation, ice makers, and RO systems. If the meter’s leak indicator spins, you likely have a supply side leak.
-
Hot water isolation
- Turn off the water heater’s cold inlet. If the meter stops, the leak is on the hot side. If it keeps spinning, suspect the cold side.
-
Listen and map
- At night, listen for hissing. Use tape to mark warm spots or damp areas to share with your plumber.
-
Pressure check devices
- If you have a whole home pressure gauge, confirm static pressure between 55 and 75 psi. Anything higher suggests a PRV issue.
If any test suggests a leak, avoid running fixtures on that branch and schedule a professional evaluation.

Frequently Asked Questions
How do I know if I have a slab leak versus a regular plumbing leak?
Look for a combination of signs near interior walls or floors, like warm spots, running water sounds, and meter movement with all fixtures off. Exterior puddles often point to yard leaks instead.
Will homeowners insurance cover a slab leak repair?
Policies vary. Many cover access and resulting damage but not the pipe repair itself. Document the issue with photos and video and call your insurer for specifics.
Can trenchless methods fix a slab leak?
For drains and sewers under the slab, yes. UV cured CIPP lining or pipe bursting can repair or replace lines with minimal excavation. For water supply leaks, reroutes are often best.
How fast can you detect and repair a slab leak in Provo or Orem?
Same day diagnostics are often available. Many spot repairs or reroutes can be completed within one to two days after approval, depending on access and finish work.
Is it safe to wait a week if the leak seems small?
Not recommended. Even slow leaks can wash out soil, grow mold, and raise utility bills. Shut water to the leaking branch and schedule service promptly.
