Backflow prevention devices protect your drinking water by keeping it free of pollution or contamination caused by backflow. But what exactly is backflow? Backflow occurs when contaminated water is allowed to reverse back into distribution pipes. Reversal of water flow can cause all kinds of contaminants to enter the distribution system, exposing you, your family and your neighbors to potentially dangerous chemicals. Backflow testing and certification by a Chelan Backflow technician will ensure compliance with all the state of Washington’s codes and regulations.

Backflow preventers are mechanical devices with moving parts, washers and seals that can wear down. At Chelan Backflow, we can provide annual testing to ensure your unit is functioning properly. Our certification will also give you peace of mind that you are doing all you can to protect our Lake Chelan Valley water supply. It’s the law and it’s the right thing to do for the environment.
