How to find a water leak
All houses have a main water shut-off valve. Make sure you know where your home’s is in case of emergency or routine maintenance. Cracks or leaks around the water main could signify a plumbing issue.
After searching your home, if you don’t see any of the water damage signs mentioned above, you can test for a leak by checking your water meter. First, turn off the water to your home and note the number you see on the meter. Twenty minutes later, if the number on the meter has changed, you’ll know there is a leak in your system.2
Looking for signs of water damage is one way to prevent further issues. Stopping problems to begin with, however, starts with routine maintenance.
