Not every leak announces itself with a puddle. Slow leaks inside walls, under floors, or underground can run for weeks before the damage shows. A few simple checks can tell you whether you may have one.
Do a Water Meter Test
1
Turn Everything Off
Make sure no one is using water and that appliances such as the dishwasher and washing machine are not running.
2
Read the Meter
Note the reading, or watch the small leak indicator on the meter.
3
Wait and Compare
Wait 30 to 60 minutes without using any water, then check again. If the reading has changed, water is going somewhere.
Other Signs to Watch For
- Unexplained increases in your water bill.
- Musty odors or visible mold in walls and ceilings.
- Stained, bubbling, or peeling paint and wallpaper.
- Warm spots on the floor, which can point to a hot water line leak.
- The sound of running water when everything is off.
What to Do Next
If a meter test or other signs point to a leak, call a provider. They can use acoustic listening devices and thermal imaging to locate the source with minimal opening of walls and floors.
