Backflow Preventer

Cross Connection Control & Backflow

Cross-Connection – is the physical connection between the potable (drinking) water system and an “end-use” (water utilizing fixture, equipment, or process) where a potential water contaminating hazard exists.

Backflow is caused by cross-connections that have the potential of allowing contaminants into the drinking water system. Back siphonage can occur when the pressure in a tank or water trough is lower than the water system’s pressure. This could allow the influx, or pulling, of contaminated water into the system.

A backflow preventer is a device that’s installed on your home’s water pipes that allows water to flow in one direction but never in the opposite direction. Its sole job is to prevent drinking water from being contaminated due to backflow.

Other Water Uses

Consult with a licensed plumber regarding proper connection and protection requirements or contact a Service Department inspector at (419) 683-3800.

Best Management Practices

Understanding and respecting the risk of water contamination is a great start, when in doubt, seek help. Basic guideline: every water outlet needs some form of protection; get to know what is needed.

Have “non-testable” backflow devices replaced at the intervals described above. Have “testable” backflow assemblies tested yearly and rebuilt or replaced as needed (usually every 5-8 years).
