There are a few tell-tale signs that you may have a water leak:
- A high water bill
- Dampness or water marks
- Puddles, drips or gushing water
- Sound of running water
- Water loss on the water meter.
Some burst pipes or leaks are easy to spot. You may be able to trace the source of a puddle or drip. You might see water stains on the drywall. If the damage happens on an exposed pipe, you can see the hole. Other leaks are hidden behind walls and not so obvious.
If you suspect a leak, turn off all appliances that use water, and don't use any taps, toilets or other sources of water during the test. Look at the water meter. After 30 minutes, check it again to see if it moved at all during that time. If it did, you have a leak.
Once you know you have a leak, you can do a little more investigating within your home to locate the source. Look for the visible signs of leaks to figure out where the problem lies. Start with obvious spots like toilets, sinks and showers. If you can't find the leak yourself, a plumber can help you find and fix the problem.
