You've received a notice from Colorado Springs Utilities about backflow testing, or your plumber mentioned that your backflow preventer needs an annual inspection. You're not entirely sure what a backflow preventer does, why it needs testing, or what happens if you ignore it. You're not alone—most homeowners don't think about their backflow prevention device until they're required to have it inspected.
Backflow testing is a regulatory requirement in Colorado Springs, designed to protect the city's drinking water supply from contamination. Understanding what's involved, when testing is required, and how to stay compliant will save you headaches and help protect public health. Here's what Colorado Springs homeowners need to know about backflow prevention testing.
What Is a Backflow Preventer and Why Does It Matter?
A backflow preventer is a valve installed in your plumbing system that allows water to flow in only one direction—into your home or business—and prevents it from flowing backward into the public water supply. Under certain conditions, water pressure can reverse, causing water from your property to flow back into the city's water lines. That's called backflow, and it's a serious public health concern.
Backflow can occur in two main scenarios. The first is back-pressure, which happens when the pressure in your plumbing system exceeds the pressure in the public water supply. This can occur with boilers, heated water systems, or elevated storage tanks. The second is back-siphonage, which happens when there's a sudden drop in water pressure—such as during a water main break, heavy firefighting demand, or when a nearby hydrant is used heavily. When pressure drops in the city lines, contaminated water from your property can be sucked back into the public system.
In Colorado Springs, where altitude affects water pressure and our dry climate means irrigation systems are common, backflow prevention is especially important. Sprinkler systems connected to fertilizers or pesticides, fire suppression systems, boilers, and even certain residential plumbing configurations can all create backflow risks if not properly protected.
Colorado Springs Utilities requires backflow preventers on any connection that poses a potential contamination risk. If your property has an irrigation system, a fire sprinkler system, a boiler, a commercial kitchen, or certain other plumbing configurations, you likely have a backflow prevention device that requires annual testing.
Colorado Springs Testing Requirements and Compliance
Colorado Springs Utilities mandates annual testing for most backflow prevention assemblies. The testing must be performed by a state-certified backflow tester. This isn't optional—it's a regulatory requirement tied to your water service. If you fail to have your device tested on time, Colorado Springs Utilities can and will take action, including potential service interruption.
The testing schedule is based on the type of device and the level of hazard it protects against. Most residential irrigation systems with backflow preventers require testing once per year. Commercial and industrial properties may have more frequent testing requirements depending on the type of backflow device and the hazard classification. High-hazard connections—such as those in medical facilities, chemical processing, or food service—often have stricter schedules.
When testing is due, you're responsible for hiring a certified tester and ensuring the test is completed. The tester will submit the results directly to Colorado Springs Utilities, so you don't have to file paperwork yourself. However, you should keep a copy of your test report for your records. If your device fails the test, you'll need to have it repaired or replaced and retested before it's considered compliant.
Colorado Springs Utilities typically sends reminder notices to property owners when testing is due, but the responsibility ultimately falls on you. Missing your testing deadline can result in fees, mandatory compliance schedules, or in extreme cases, water service disconnection. The city takes backflow prevention seriously because contaminated water in the public supply affects everyone.
It's worth noting that if you're buying a home in Colorado Springs, backflow testing compliance may come up during the inspection process. Lenders and title companies sometimes require proof that backflow devices are up to date before closing. Sellers should plan ahead and ensure their backflow testing is current before listing their property.
What Happens During a Backflow Test?
A backflow prevention test is a straightforward procedure, but it requires specialized equipment and training. A certified backflow tester will inspect your device, verify it's the correct type for your application, and perform a series of pressure tests to ensure the internal components are functioning properly.
The tester will attach a test kit—a gauge assembly designed to measure pressure differentials—to specific test ports on your backflow preventer. They'll open and close valves in a specific sequence, checking that the device's check valves, springs, and seals are holding pressure as designed. They're looking for leaks, pressure drops, or any sign that water could flow backward through the device.
For a typical residential irrigation backflow preventer, the test takes about 20 to 30 minutes. The tester will also inspect the device visually for signs of wear, corrosion, or damage. In Colorado Springs, our dry climate and temperature swings can cause seals and gaskets to degrade faster than in more humid climates, so visual inspection is an important part of the process.
If the device passes, the tester submits a passing report to Colorado Springs Utilities, and you're compliant for another year. If it fails, the tester will identify what's wrong—often a worn check valve, a faulty relief valve, or a degraded seal. In many cases, the tester can make minor repairs on the spot if they carry the necessary parts. More serious failures may require replacing the entire assembly.
After repairs, the device must be retested and pass before it's considered compliant. Some testers include one retest in their service fee; others charge separately. It's a good idea to ask about retest fees upfront when you schedule your initial appointment.
Choosing a Certified Backflow Tester in Colorado Springs
Not just any plumber can test your backflow preventer. Colorado requires backflow testers to hold specific state certification. Colorado Springs Utilities maintains a list of certified testers, though they don't endorse or recommend specific individuals—you're responsible for choosing and hiring your own tester.
When you're looking for a backflow tester, start by verifying their certification. Ask for their Colorado backflow tester certification number and check it against the state registry if you want extra assurance. Certified testers are required to complete initial training and continuing education to maintain their credentials, so you're hiring someone who's up to date on Colorado's standards and best practices.
Cost is another consideration. Backflow testing fees in Colorado Springs typically range from $50 to $150 for a standard residential test, depending on the device type, accessibility, and whether repairs are needed. Irrigation system backflow preventers are usually on the lower end of that range. More complex devices—such as reduced pressure zone (RPZ) assemblies used for higher-hazard applications—may cost more to test.
Some homeowners use the same tester every year and set up automatic annual reminders. This approach works well because the tester becomes familiar with your property and device, and you're less likely to forget your testing deadline. Other homeowners shop around each year for the best price. Either approach is fine—just make sure you don't miss your deadline.
It's also worth asking whether the tester can perform repairs if your device fails. Some testers carry common repair parts and can fix minor issues on the spot. Others only test and refer you to a plumber for repairs. Knowing this upfront can save you time if your device fails inspection.
Accessibility matters too. If your backflow preventer is buried, obstructed, or difficult to reach, you may face higher testing fees. Testers charge more when they have to dig out a device, move landscaping, or access a cramped space. Keeping your backflow preventer accessible year-round makes testing easier and less expensive.
Common Backflow Testing Issues in Colorado Springs
Colorado Springs' climate creates specific challenges for backflow prevention devices. Our temperature swings—hot summer days and freezing winter nights—cause expansion and contraction that can wear out seals and gaskets faster than in more temperate climates. Rubber components dry out in our low humidity, leading to cracks and leaks. These are normal wear patterns, but they mean Colorado Springs homeowners should expect occasional repairs as part of routine testing.
Irrigation system backflow preventers are especially vulnerable because they're often installed outdoors and exposed to the elements. Freezing is a common problem. Even though irrigation systems are winterized in the fall, a backflow preventer that wasn't properly drained or insulated can freeze and crack. If you've had a hard winter, don't be surprised if your backflow preventer fails its spring test due to freeze damage.
Another common issue is vandalism or accidental damage. Backflow preventers installed above ground in accessible locations can be kicked, hit by lawn equipment, or damaged during landscaping work. Valves can be bumped, test cocks broken off, or protective covers removed. If your backflow preventer is in a high-traffic area, consider installing a protective cage or relocating it to a safer spot.
Older devices naturally degrade over time. A backflow preventer that's 10 or 15 years old may start failing tests more frequently, even with repairs. At some point, replacement becomes more cost-effective than repeated repairs. A certified tester can advise you when your device has reached the end of its useful life.
Some homeowners don't realize they have a backflow preventer until they receive a testing notice from the city. If you've recently purchased a home or moved into a property with an irrigation system, locate your backflow preventer early. It's usually installed near your water meter, at the irrigation system connection, or along an exterior wall. Knowing where it is and understanding its testing schedule will help you stay compliant from day one.
What to Do If Your Backflow Preventer Fails
If your backflow preventer fails its annual test, don't panic. Failures are common and usually repairable. The tester will explain what's wrong and what needs to be fixed. In many cases, a failed test is due to a worn rubber seal, a stuck check valve, or a relief valve that's not opening at the correct pressure. These are routine repairs.
Your options depend on the severity of the failure. Minor issues—such as a dirty valve or a small leak—can often be repaired on the spot if the tester carries parts. The device is then retested immediately, and if it passes, you're compliant. More significant problems—such as a cracked body, severe corrosion, or multiple failed components—may require replacing the entire assembly.
If replacement is necessary, you'll need to hire a licensed plumber to install a new backflow preventer. The new device must meet current Colorado Springs code requirements and be appropriately sized for your application. After installation, it must be tested by a certified tester before Colorado Springs Utilities will accept it as compliant.
Replacement costs vary depending on the device type and installation complexity. A basic atmospheric vacuum breaker for a residential irrigation system might cost $150 to $300 installed. A more sophisticated reduced pressure zone (RPZ) assembly can run $500 to $1,500 or more, depending on size and installation requirements. Your plumber can give you a detailed estimate based on your specific situation.
Once repairs or replacement are complete, the tester submits a passing report to Colorado Springs Utilities, and you're back in compliance. Keep a copy of the report for your records. If you're making repairs late in the year and your testing anniversary is approaching, ask the tester whether you'll need another test soon—sometimes a device tested late in the compliance period will need retesting within a few months.
Staying Ahead of Your Testing Schedule
The easiest way to stay compliant is to schedule your backflow test at the same time every year. Many homeowners tie it to another seasonal task—such as spring irrigation startup or fall winterization—so it becomes part of their annual home maintenance routine. Set a calendar reminder for a few weeks before your testing deadline so you have time to schedule an appointment without rushing.
If you use a lawn care company or irrigation service, ask whether they offer backflow testing as part of their seasonal services. Some do, which simplifies scheduling. If they don't, they can often recommend a certified tester they work with regularly.
Keep your backflow preventer accessible year-round. Don't bury it under mulch, plant shrubs around it, or stack equipment against it. Testers need clear access to perform the test, and obstructed devices lead to higher fees or delayed testing. Mark the location clearly if it's not obvious—a small flag or marker can save time when the tester arrives.
If you're a landlord or manage rental properties in Colorado Springs, make sure your tenants know they're not responsible for backflow testing—you are. Property owners are legally responsible for compliance, even if tenants occupy the property. Build testing costs into your annual maintenance budget and handle scheduling yourself.
Finally, if you're planning major landscaping, irrigation upgrades, or plumbing work that involves your backflow preventer, make sure the contractor knows it must be tested after any work is completed. Colorado Springs Utilities requires testing whenever a backflow device is repaired, relocated, or replaced. Don't assume your contractor will handle it—confirm who's responsible before the work begins.
