A lot of leaks go unnoticed, especially leaks related to outdoor plumbing and the main water line that feeds the house. These lines are often very old and they are some of the most common to break down over the years. If your water usage has not increased, but your bill has, you may have a water leak. This leak could be anywhere on your property so it’s important to have your plumbing system inspected for leaks by a leak detection specialist.
