Introduction
Not all leaks are alike. The nature of a leak (its type, location, size) affects how urgent it is, how complex to fix, and how much damage it may cause. In this blog, we’ll go over the main types of water leaks, what to watch for in each case, and how specialists in leak detection tackle them—especially those in Upland, CA.
Types of Leaks
Here are some of the more common categories of leaks in homes and commercial buildings:
- Slab leaks
- Pipes running under concrete foundations.
- Caused by corrosion, shifting soil, before/after construction issues.
- Hard to find; often show up via hot spots in floor, cracks in slab, unexplained high bills.
- Wall or ceiling leaks
- Usually from plumbing lines, roof leaks, or condensation.
- Evidence: stains, peeling paint, bubbling wallpaper, drips/sounds.
- Fixture leaks
- Faucets, showerheads, toilets.
- Often easier to detect and repair. Small parts (washers, flappers, gaskets) fail over time.
- Service line leaks
- The main line from water meter to the house or building.
- Underground, often hidden, can lead to serious water waste and property damage.
- Outdoor and irrigation leaks
- Sprinkler systems, hoses, underground irrigation lines.
- Saturated soil, soggy lawn, constant water flow at meter when system is off.
- Sewer leaks
- Leaks in sewer lines, joints, or connections.
- Can cause bad smell, ground sinkage, health hazards.
Typical Warning Signs by Leak Type
| Leak Type | Common Early Signs | Why Early Detection Matters |
|---|---|---|
| Slab leaks | Warm spots on floor, sudden spike in water bill, damp carpets | Slab damage costly; moisture leads to foundation compromise |
| Wall/ceiling leaks | Stains/discoloration, musty smell, peeling paint | Mold risk, structural weakening |
| Fixture leaks | Continuous drip, water pooling, toilet runs when flushed | Even small leaks waste water and raise bills |
| Service line leaks | Wet spots in yard, meter running while house seems dry | Could be underground; large water loss before visible signs |
| Irrigation leaks | Patchy or lush growth, soggy ground, system pressure loss | Wastes water; can damage landscaping/hardscaping |
| Sewer leaks | Odor, soggy ground, gurgling drains | Health hazard; potential for large repair |
Methods for Detecting Specific Leak Types
Each leak type requires different detection strategies. Here are how experts approach various leak types:
- Slab leak detection
- Thermal imaging or infrared scans to find hot/cold anomalies.
- Acoustic detection (listening equipment) for sound of water under concrete.
- Moisture meters inserted into slab or under floor coverings.
- Wall/ceiling leaks
- Visual inspection for stains, bulges in drywall.
- Thermal imaging.
- Checking plumbing runs behind walls; shutting off parts to isolate.
- Service line & underground leaks
- Checking water meter usage with no visible water usage.
- Using ground microphones or listening devices.
- Excavation only when precise leak location found.
- Fixture and small plumbing leaks
- Dye tests (toilet, tanks).
- Listening for drips.
- Disassembling fixtures to inspect washers, seals, flappers.
- Irrigation leaks
- Inspecting sprinkler heads, valves, hose fittings.
- Checking for soggy areas that stay wet.
- Pressure tests on irrigation lines, monitoring water meter when system off.

What You Can Do While Waiting for a Pro
While waiting for professional help, some steps you can take:
- Shut off the water at the main valve if leak is severe.
- Move furniture, rugs, etc., away from wet areas to prevent damage.
- Use buckets or towels to absorb water and reduce mold risk.
- Document the signs (photos, bills, etc.)—useful for professionals or for insurance.
- Avoid delaying—delays often lead to worse damage.
Cost & Time Factors to Understand
While avoiding “guarantees,” it helps to understand what influences cost and duration of leak detection & repair:
- Location of the leak: under slab or in wall = more labor/time.
- Accessibility: exposed plumbing vs hidden lines.
- Type of detection technology required.
- Extent of damage already caused.
- Repair complexity (simple component replacement vs pipe rerouting).
Knowing these ahead of time helps you set realistic expectations.
