Leaking water pipes can cost homeowners hundreds of dollars every year. A higher-than-normal water bill might be your first indication of a leaking pipe. Or you might hear the sound of running water even when all your water fixtures are turned off. When you suspect a leak, check the fixtures first to make sure all the faucets are tightly closed. Then go to the water meter, if you have one. If the dial is moving, you're losing water somewhere in the system.
If your experience working with your home’s plumbing is limited, you may want to keep your head above water and hire a professional plumber to do the job. Make sure he or she is properly licensed and has a passing grade with your BETTER BUSINESS BUREAU.
