What is a backflow preventer?

Backflow is the reversal of water flow, and it can present a risk to water quality in public water systems. That's why water utilities require some customers to install a backflow preventer. The video below by Charleston Water explains how backflow occurs and how prevention assemblies work.

​

Why do I need a backflow device on my lawn irrigation system?
Backflow preventers are required by the Ohio Environmental Protection Agency (EPA); Ohio law (Ohio Administrative Code 3745-95), and the Ohio Plumbing Code (chapter 608) to be installed where there is a potential health or contamination threat within the consumer’s plumbing system. Most commercial buildings and residential properties with in-ground irrigation systems require a backflow prevention device.

Why does a backflow device have to be tested on an annual basis?
To ensure the device is working properly, the consumer is required to have annual testing done by a state-certified backflow tester. Reports of this annual testing must be maintained by the consumer and forwarded to their Division of Water. The water department sends out reminder letters 30 days before your backflow test due date.
