Backflow Testing & Prevention in Fort Collins, CO.

Backflow prevention exists to keep contaminated water from siphoning back into the clean water supply, and many Fort Collins properties, particularly those with irrigation systems, are required to have a device tested regularly. Fort Collins 24/7 Plumbing tests, repairs, and installs backflow prevention devices for both homes and commercial properties. Staying current on testing isn't just a formality, since a failed or missing backflow device is a real risk to the broader water supply, not just a paperwork issue.

Who Actually Needs Backflow Testing.

Properties with irrigation systems are the most common candidates for a required backflow prevention device, since an irrigation line creates a direct connection between the clean water supply and an outdoor system that could otherwise siphon contaminated water backward under certain pressure conditions. Commercial properties with certain equipment, like boilers or fire suppression systems, often have similar requirements. Backflow prevention itself is a requirement under the Colorado Plumbing Code (based on the International Plumbing Code, or IPC), not just a local preference. If the cause turns out to be broader than expected, Commercial Plumbing is usually the next relevant page.

Diagnosis.

How Backflow Testing Works.

A certified test involves checking the device's check valves and relief valve under controlled pressure conditions to confirm it's actually preventing backflow as designed, not just installed correctly. Results are documented for submission to whatever authority requires the test, whether that's the water utility or a local jurisdiction. Most tests take well under an hour, and if the device fails, we can typically quote and complete the needed repair during that same visit.

Staying Ahead of Your Testing Deadline.

Staying Ahead of Your Testing Deadline.

Missing an annual backflow test deadline can sometimes affect your water service or trigger a compliance notice, so it's worth keeping track of your specific due date rather than waiting for a reminder. We can schedule your test proactively each year on the same cycle, which is generally simpler than having to react once a notice arrives. Keeping the physical device area clear of landscaping overgrowth also makes each year's test faster and helps a technician spot any visible corrosion early. Homes dealing with this often need Water Filtration Installation addressed around the same time.

What to Do If Your Backflow Device Has Failed.

  • Discolored, cloudy, or unusually smelling water from an indoor tap, especially right after irrigation runs.
  • Visible corrosion, cracking, or leaking at the device itself.
  • A failed annual test result from any provider, yours or a previous one.
  • If you notice any of these, stop using the affected water source for drinking or cooking and call a technician.
