How to check for plumbing leaks
Start with visible clues, then use your water meter during a period when no one is using water. A changing meter can point to a possible leak that needs further investigation.

Use the meter as a clue
EPA WaterSense recommends taking a meter reading, avoiding all water use for two hours, and checking the meter again. If it changes, there is probably a leak. You can also look beneath sinks, around toilets, at faucets, and around appliance water connections for moisture or corrosion.
Record what you find
Photograph the location, note the date and the meter readings, and keep invoices from repairs. A licensed plumber is the right next step for a suspected hidden leak, damaged pipe, or a repair beyond your experience.
