The water supply to your home is normally under pressure, but situations can occur causing this pressure to drop. These low-pressure situations can cause water to flow backward. This reversal of water flow is known as backflow. A water main break, repair of a water main, or water use for fire fighting can result in enough lost water pressure to cause backflow.
Backflow can be a health hazard for your family. When backflow occurs the water drawn back into your main water supply may be contaminated. This contaminated water remains in the water lines until it is drained from another fixture in your home. A serious health hazard could result when this contaminated water is used for drinking, cooking or bathing. To prevent this from occurring Clermont County Public Health requires annual testing by a certified backflow tester for testable backflow devices.
Most plumbing companies have a certified backflow tester on staff. We recommend checking the yellow pages under plumbing or backflow tests to find a certified backflow tester in your area. You may also view a list of certified backflow testers on the Ohio Department of Commerce website.
