Prevent Leaks at Home to Avoid Higher Water & Sewer Charges
Water leaks—whether visible or hidden—can significantly increase your water and sewer charges. Even small, slow leaks waste more water than most people realize. By taking a few simple steps, you can protect your home, conserve water, and avoid unexpected utility costs.
Common Sources of Household Leaks
Toilets: A running or faulty flapper can waste 3 gallons per minute hundreds which wastes 4,320 gallons per day.
Faucets & Showerheads: Dripping fixtures may seem minor, but they also add up quickly.
Pipes & Plumbing Joints: Hidden leaks behind walls, under sinks, or in crawl spaces can cause both high bills and property damage.
Outdoor Spigots & Irrigation Systems: Loose connections and broken sprinkler components often leak unnoticed.
How to Prevent and Detect Leaks
Monitor Your Water Meter
Turn off all water-using appliances.
Check the water meter; if it continues to move, you likely have a leak.
For slow leaks, note the reading and check again after a few hours (no water use).
Look for Visible Signs
Ceiling or wall stains
Peeling paint or bubbling drywall
Warped flooring or soft spots
Mold or mildew growth
Damp or musty smells
Listen for Unusual Sounds
Hissing or dripping noises behind walls or under floors.
Toilet continuously running or filling.
Toilet Leak Test
Add food coloring to the toilet tank.
Wait 15–30 minutes without flushing.
If colored water appears in the bowl, the flapper or valve is leaking.
Check Your Water Bill
Monthly increases without a change in usage often point to hidden leaks.
Inspect Appliances and Fixtures
Check for drips, moisture, or corrosion around:
Under-sink plumbing
Water heaters
Dishwashers
Washing machines
Refrigerator water lines
Use Leak Detection Devices
Smart leak detectors placed under sinks, near heaters, or in basements.
Some detect moisture; others monitor flow and shut off water automatically.
Use Infrared Cameras or Moisture Meters
Moisture meters can detect dampness inside walls.
Infrared cameras show temperature differences caused by wet areas.
Check Outdoor Systems
Irrigation system leaks
Hose bibs dripping
Wet patches in the yard when it hasn't rained
Professional Leak Detection
Plumbers can use acoustic sensors, thermal imaging, or pressure tests to locate hidden leaks.
Why Preventing Leaks Matter
Fixing leaks promptly not only keeps your utility bills manageable but also helps conserve water and protects your home from costly repairs. Regular inspections and quick repairs are the easiest way to stay ahead of potential problems.
