• Backflow Install and Testing

  • Most of the time water flows "forward" from the water supply system into your home. Backflow is the term used to describe the "backward flow" of water into the water supply system. Backflow can be caused by either back pressure or back-siphonage of your irrigation systems. If water flowing backwards contains hazardous chemicals or bacteria, it can cause an unhealthy or dangerous situation. In order to address this potential problem on a community-wide level, The Safe Drinking Water Act requires that every irrigation system have a registered and inspected backflow preventer device installed. Deschutes Environmental Services, Inc. is certified and experienced in new installation, regular maintenance, and annual testing of backflow prevention devices.

  • The Federal Safe Drinking Water Act ORS 448.273 requires that every irrigation system have a registered and inspected backflow preventer device installed.

  • Experience has shown that there is not a mechanical device that can be depended upon unless it is checked, tested and maintained on a regular basis. Backflow Prevention devices are required to be installed in specific locations to protect the safety of the drinking water. These devices must be tested annually. In Oregon it is required by law. Deschutes Environmental Services, Inc. is qualified to administer the Backflow device test and once completed will forward the results of that test to your water purveyor.
