Water leaks are one of the most common and costly problems homeowners face. Whether it’s a slow drip from a faucet or a hidden pipe leak behind a wall, undetected leaks can lead to significant damage, higher water bills, and costly repairs. That’s why learning how to detect a leak early is crucial for maintaining a safe, efficient, and comfortable home.
At Larratt Bros Plumbing, with over 30 years of experience serving the Bay Area, we specialize in expert leak detection and plumbing repairs. From routine household fixes like toilet repair & installation, sink leaks, or garbage disposal installation to larger projects involving sewers, drains, and water heater repair & installation, we handle it all with professionalism and care.
In this guide, we’ll walk you through how to spot leaks, including those that aren’t visible, trace their source, and understand when it’s time to call in the professionals. Whether you’re tackling minor repairs or planning larger renovations, knowing the basics of leak detection can save you time, money, and stress.
How Can a Leak Be Detected?
Detecting a leak early is key to preventing water damage and costly repairs. Here are some common ways to identify if your home has a leak:
1. Look for Visual Signs
- Water stains or discoloration on walls, ceilings, or floors
- Mold or mildew growth in damp areas
- Warped or bubbling paint and wallpaper
- Puddles or damp spots around fixtures like sinks, toilets, bathtubs, or showers
2. Listen for Sounds
- Unexplained dripping or running water noises when no fixtures are in use
- Sounds of water flowing behind walls or under floors
3. Use Leak Detection Tools
- Moisture meters to detect dampness behind surfaces
- Infrared cameras that highlight temperature differences caused by moisture
- Water leak detectors that alert you when water is present in unwanted areas
At Larratt Bros Plumbing, we use advanced leak detection technology to pinpoint leaks quickly and accurately. Early detection means less damage and faster repairs, whether it’s a minor faucet drip or a hidden issue in your sewers or drains.
How to Find a Leak That’s Not Visible
Sometimes leaks aren’t obvious — they can hide behind walls, under floors, or within plumbing systems. Detecting these hidden leaks requires a bit more investigation and specialized techniques:
1. Monitor Your Water Meter
- Turn off all water fixtures in your home
- Check the water meter and note the reading
- Wait a couple of hours without using water, then check the meter again
- If the meter reading has changed, it’s a strong sign of a hidden leak
2. Watch for Unexplained Increases in Water Bills
- Sudden spikes in your water usage often indicate a leak somewhere in your plumbing system.
3. Use Pressure Testing
- A plumber can perform a pressure test on your water lines to detect drops in pressure that signal leaks.
4. Employ Advanced Leak Detection Tools
- Thermal imaging cameras reveal temperature differences caused by moisture behind walls and floors
- Acoustic leak detectors pick up the sound of water escaping from pipes
5. Inspect Susceptible Areas
- Check areas prone to leaks such as under sinks, behind toilets, near water heaters, and around bathtubs and showers
Hidden leaks can cause serious damage if left untreated. That’s why Larratt Bros Plumbing recommends professional leak detection services, especially for complex issues involving sewers, drains, or water heater repair & installation.
How Can I Trace a Water Leak?
Tracing a water leak involves systematically narrowing down the source to pinpoint the exact location, which can save time and prevent unnecessary repairs. Here’s how you can trace a leak effectively:
1. Start with the Obvious Places
- Inspect all visible plumbing fixtures such as sinks, toilets, bathtubs, showers, and faucets for signs of dripping or pooling water.
- Check under cabinets and around drains for moisture or water stains.
2. Follow the Water Trail
- Look for damp spots, discoloration, or mold on walls, floors, and ceilings that might lead back to the leak.
- Pay special attention to areas near your water heater or garbage disposal installation since leaks often originate there.
3. Check Your Water Meter
- As mentioned earlier, monitoring your water meter can confirm if there’s an active leak.
- If the meter keeps running even when all water is off, it helps narrow down the problem.
4. Examine the Sewer and Drain Lines
- Slow drains or foul odors can indicate leaks or breaks in sewers and drains.
- A professional plumber can perform a camera inspection to trace leaks in underground or hidden pipes.
5. Use Leak Detection Devices
- Moisture meters, thermal cameras, and acoustic leak detectors can help pinpoint leaks hidden behind walls or floors.
6. Call in the Professionals
- Tracing leaks in complex plumbing systems requires expertise and specialized tools.
- At Larratt Bros Plumbing, we combine years of experience with advanced leak detection technology to locate leaks accurately and efficiently.
Can I Rent a Water Leak Detector?
If you suspect a leak in your home, you might wonder whether renting a water leak detector is a good option. Here’s what you need to know about DIY leak detection tools:
Rental Options for Leak Detection Tools
- Many hardware stores and equipment rental companies offer basic water leak detectors and moisture meters for rent.
- These tools can help identify surface leaks or damp spots, but their effectiveness varies depending on the complexity of the leak.
Pros of Renting a Leak Detector
- Cost-effective for simple leak checks
- Convenient if you only need to detect a small, visible leak
- Can help you take immediate action to prevent further damage
Cons of DIY Leak Detection
- Limited accuracy for hidden or complex leaks in pipes, sewers, or behind walls
- Lack of expertise to interpret the readings correctly
- Risk of missing critical issues that require professional tools and knowledge

Does Homeowners Insurance Pay for Leak Detection?
Many homeowners wonder whether their insurance covers the costs associated with detecting and repairing water leaks. The answer depends on your specific policy and the circumstances surrounding the leak.
What Homeowners Insurance Typically Covers
- Most standard policies cover sudden and accidental water damage caused by leaks, such as a burst pipe flooding your home.
- Coverage often includes repairs to damaged walls, floors, and personal property resulting from the leak.
What Homeowners Insurance Usually Does Not Cover
- Damage caused by slow leaks or leaks that result from lack of maintenance over time.
- Preventative leak detection or routine plumbing repairs are generally not covered.
Does Insurance Pay for Leak Detection?
- Some policies may cover the cost of locating a leak if it is related to a covered loss, like a burst pipe.
- However, many insurers exclude the cost of leak detection itself, especially if the leak has been ongoing or due to negligence.
Tips for Homeowners
- Review your insurance policy carefully to understand your coverage limits.
- Document any water damage and repairs promptly when filing a claim.
- Contact your insurance provider to clarify whether leak detection costs are reimbursable.
