Backflow Services

Most commercial properties, industrial and multifamily customers must comply.  In some cases residential customers with high hazards such as well water may also have to comply.  Additionally, some changes in plumbing codes require new homes with fire lines to have backflow prevention devices as well.  In general, all domestic, irrigation and fire lines on these properties must have backflow devices installed.  Letters are generally sent to these customers on an annual basis to remind them of testing.  If no action is taken, the city may shut-off water service until a test can be scheduled or performed.

We have included pictures of backflow assemblies to help you identify what these look like.  Usually these can be located by identifying where the water enters your property (generally in basements by water heaters, crawl spaces and mechanical rooms).  Our plumbers are trained in locating these and can help you if you have questions.

Our testers are licensed plumbers that are certified through the ASSE and ABPA.  We are certified to test domestic, irrigation and fire backflow prevention assemblies and are registered as a Fire Suppression Contractor with The Colorado Division of Fire Safety.  It is important to know that not all plumbers are certified to test devices even though they are able to install them, just as not all testers have the plumbing qualifications to repair or install the devices.  This is important in saving the customer time and money.  We are qualified and certified to do both.  We are also fully insured and certificates are available upon request.  In addition, Streamline Plumbing keeps an accurate database of all our customers and their devices to make annual testing as easy as possible by working with the city.  We fill out all paperwork and submit it for you and keep all copies of test reports in the event copies are ever needed.

Backflow is the reversed flow of water which can contaminate drinking water. The State of Colorado and our local city governments have programs in place that require annual backflow device testing by a certified tester to ensure that our drinking water remains safe. There are different assemblies required for different hazard levels, and the installation and repairs of these can differ greatly.

Annual testing of backflow prevention devices is required for most commercial properties, industrial facilities, and multifamily housing units. Some residential properties, especially those with higher risks (such as properties with wells or other water hazards), may also need to comply. Changes in plumbing codes have made it mandatory for newer homes with fire lines, irrigation systems, and other water line configurations to have backflow prevention devices installed. In many areas, cities issue annual reminders to property owners. If testing is not completed as required, the city may restrict water service until the testing is done.

Identifying a backflow prevention device is usually straightforward. These devices are often installed where water enters your property, commonly found in basements, near water heaters, or in mechanical rooms. To help customers recognize their devices, we provide pictures of different backflow assemblies. If you’re unsure about your setup, our certified plumbers are ready to assist you in locating and identifying your device.

Only licensed and certified plumbers, trained specifically in backflow prevention, should handle testing and repairs. Our technicians are certified by the ASSE and ABPA, allowing them to test and repair both domestic and irrigation backflow assemblies. We’re also registered as Fire Suppression Contractors with the Colorado Division of Fire Safety. While not all plumbers have the necessary qualifications, our team is fully trained to perform these services. We also maintain an organized database to ensure all our clients meet annual testing deadlines seamlessly, and we handle all necessary paperwork to streamline the process.
