Annual Backflow Testing in Denver
Most water providers require backflow assemblies to be tested at least once a year. Our certified testers connect a calibrated differential pressure gauge and check each check valve and relief valve. Test results are recorded on the provider's form and submitted for you. If the assembly passes, you are done until next year.
Freeze and Heat Protection for Backflow Preventers in Denver, CO
Above-ground backflow assemblies are exposed to summer sun and winter cold. Before leaving a home for a winter trip, keep the heat at a safe setting and consider shutting off the main water supply. Freezing can crack bodies and bonnets, while UV exposure breaks down plastic parts. We install insulated pouches, heated enclosures or lockable cages as needed. Protecting the assembly helps it pass testing and last longer.

Frequently Asked Questions About Backflow Preventer in Denver
Backflow preventer testing in Denver, CO typically costs between $75 and $150. This fee covers the technician's visit, the test itself, and the submission of required reports to your local water authority. Complex commercial systems or multiple devices may carry higher costs.
Water providers may send follow-up notices, charge fees or eventually suspend service. Scheduling early avoids these problems. We can often fit urgent tests in quickly.
New installations and replacements often require a plumbing permit and an initial test. Requirements vary by city and water provider. We pull permits and handle the initial test.
If your backflow preventer fails its annual test, you will typically receive a notice from the Denver water department requiring prompt repair or replacement. Our technicians can diagnose the failure, perform the necessary repairs, and retest the device so it passes inspection and avoids any service interruptions or penalties.
Most municipalities and water utilities require backflow preventers to be tested every year. This confirms the device is working correctly to protect the public water supply from contamination. We can help you schedule these regular inspections.
Signs of a failing backflow preventer include discolored water, strange odors from your tap, a noticeable drop in water pressure, or visible leaks around the device itself. If you notice any of these, contact a professional plumber immediately to assess the issue.
Backflow preventers stop contaminated water from flowing backward into the public supply during pressure drops. Irrigation, fire lines and commercial equipment are common sources of contamination. Water providers require them to protect public health.
Constant dripping from the relief valve, low water pressure and visible cracks are common signs. Discolored water or a failed test notice also indicate a problem. Prompt repair keeps you in compliance.
