1. Understand the Common Signs of a Leak

  • Unexpected Increase in Water Bill: If your water usage habits haven’t changed but your bill has spiked, a leak might be the cause.
  • Mold or Mildew: Persistent mold on non-shower walls or ceilings can indicate a hidden leak.
  • Musty Odors: If your home smells damp and musty, it could be from hidden pooled water.
  • Wet Spots: Unexplained wet or discolored spots on walls, ceilings, or floors can be a clear sign of a leak.

2. Test Your Toilet for Leaks

  • Food Coloring Test: Drop a few drops of food coloring into the toilet tank. Wait 15 minutes without flushing. If the color appears in the bowl, you have a leak.
  • Listen Carefully: Sometimes, a silent toilet leak can be heard. Listen closely for any hissing or trickling sounds.

3. Check Faucets & Under Sinks

  • Inspect Faucet Heads: Look for drips. Even a slow drip can waste a significant amount of water over time.
  • Examine Cabinets: Open the cabinets under sinks. Check for wet spots, mold, or any musty odor.

4. Investigate Appliances

  • Check the Dishwasher: Look for pooling water under or around the unit.
  • Inspect the Washing Machine: Ensure the hose connections are tight and check for wet spots on the floor.
  • Water Heater: Look for pooling water or rust around the base.

5. Outdoor Inspection

  • Hose Bibs: Turn on each hose bib, one at a time. If water seeps through the connection while the hose is running, there might be a leak.
  • Sprinkler System: Look for soggy areas in the lawn when the system is running. It might indicate a broken line.

6. Monitor Your Water Meter

  • Check the Meter: Note the meter reading. Avoid using water for two hours. If the reading changes, you likely have a leak.

7. Professional Leak Detection Services
