When Lakewood Property Owners Need Backflow Testing, Repair or Replacement
Signs you need more than a quick reset or visual check
Backflow prevention assemblies contain check valves, springs and seals that wear out over time, especially in Colorado's freeze-thaw climate and under fluctuating water pressure. Most Denver-area water providers require annual backflow testing and expect failed devices to be repaired or replaced and retested within a specific deadline to stay in compliance. Ignoring these requirements can lead to fines, water shut-off and increased risk of contamination.
- It has been more than a year since your last backflow test or you have no record of backflow testing on file
- Your backflow test failed or your water provider sent a backflow violation or final notice
- Visible leaks, constant dripping, or water spraying from the backflow preventer relief valve
- Corroded, rusted or broken backflow valves, handles or fittings
- Freeze damage: cracked backflow body after winter, especially on irrigation backflow preventers
- Recent plumbing remodel or irrigation upgrade performed without updating or retesting the backflow device

Lakewood, CO Weather and Backflow Preventer Lifespan
How Front Range climate affects backflow testing and replacement timelines
Lakewood's four-season climate brings intense sun, rapid temperature swings and repeated freeze-thaw cycles that are hard on outdoor backflow preventers, especially irrigation and hose-bib devices. Freezing water can crack the backflow body, while pressure fluctuations and sediment wear down internal components, shortening the lifespan of PVB, RPZ and double check valve assemblies and making regular backflow testing and maintenance critical.
Spring
Irrigation start-ups reveal cracked or leaking sprinkler backflow preventers after winter freeze-thaw damage.
Summer
Heavy irrigation and high outdoor water use stress backflow prevention devices and expose hidden failures under pressure.
Fall
Poor winterization leaves water trapped in backflow assemblies, increasing risk of freeze damage when temperatures drop.
Winter
Freeze-thaw cycles cause sudden leaks and bursts when systems are re-pressurized in spring without prior backflow inspection.
RPZ vs PVB vs Double Check: Best Backflow Prevention Devices for Lakewood, CO
Choose the right backflow prevention assembly for your water system
Bear Lake Plumbing tests, repairs and replaces all common backflow prevention devices, including RPZ backflow preventers, pressure vacuum breakers (PVB), double check valve assemblies (DCVA) and spill-resistant vacuum breakers. Local cross-connection control programs and Colorado plumbing code determine which device you need based on hazard level and application, and we make sure your backflow prevention system matches those requirements.
| Backflow Device Type | Best For | Key Benefits / Trade-Offs |
|---|---|---|
| Pressure Vacuum Breaker (PVB) | Residential & light commercial irrigation backflow | Cost-effective; protects against backsiphonage; outdoor-only installation |
| Double Check Valve Assembly (DCVA) | Low-hazard domestic and commercial water services | Compact; can be installed indoors; not for high-hazard contaminants |
| Reduced Pressure Zone (RPZ) | High-hazard commercial, industrial & irrigation uses | Highest protection; handles backpressure & backsiphonage; higher cost |
| Spill-Resistant Vacuum Breaker | Irrigation near buildings/paved areas | Reduces nuisance discharge; outdoor installation required |
Device Longevity in Colorado's Climate
- PVB and outdoor irrigation backflow preventers often need more frequent repair or replacement in Colorado's freeze-prone climate
- DCVA and RPZ assemblies can provide long service life when properly installed, tested annually and protected from freezing
- High-hazard sites may require more frequent backflow inspections or quicker repairs under local program rules
Our 6-Step Backflow Testing, Repair & Replacement Process in Lakewood, CO
From backflow inspection to final test report
Free Backflow Inspection & Compliance Review
We locate your existing backflow prevention assemblies, review any prior backflow test reports or violation notices, and check whether your current devices meet local backflow requirements, then recommend the right backflow testing, repair or replacement options.
Certified Backflow Testing & Results
A certified backflow tester connects calibrated gauges and performs the correct backflow test procedure for your device type, documenting results on your water provider's official backflow test form.
Backflow Device Repair & Retesting
If your backflow test fails, we can often rebuild the assembly with new internal parts and then retest the backflow preventer to confirm it passes and is safe to put back into service.
Backflow Assembly Replacement (If Needed)
When a device is corroded, damaged or obsolete, we recommend full backflow preventer replacement, installing a new code-approved assembly sized to your line and hazard level.
Documentation & Submission to Water Provider
We tag each device with test information, complete the backflow test report, and can submit it to your water provider's cross-connection control program where accepted.
Ongoing Annual Backflow Testing Reminders
To help you avoid violations and water shut-offs, we offer convenient annual backflow testing reminders and easy online or phone scheduling for future service.

Backflow Repair vs Backflow Replacement: Which Option Fits Your Lakewood Property?
Understand backflow valve repair, full device replacement and code-driven upgrades
Many backflow preventers can be restored with targeted backflow repair, such as replacing internal check kits or seals, but severely corroded or obsolete devices often need full backflow replacement to meet current program and code requirements. Local cross-connection control programs expect failed devices to be repaired and retested or replaced and tested within specific timeframes, and extended non-compliance can lead to fines or shut-off.
| Option | What It Is | Key Pros | Key Cons |
|---|---|---|---|
| Backflow Valve / Device Repair | Rebuilding existing backflow preventer with new parts | Lower upfront cost; minimal piping changes | Not ideal for badly corroded or obsolete assemblies |
| Full Backflow Assembly Replacement | Removing old device and installing new backflow prevention assembly | Longest service life; meets current code & program rules | Higher initial cost; more labor and possible re-piping |
When Full Replacement Is Recommended
- Backflow preventer is obsolete, non-testable or has no available repair kits
- Extensive corrosion, damaged body or failing shut-off valves
- Multiple failed backflow tests within a short period despite repairs
- Water provider requires an upgraded device type (for example, switching to RPZ for high-hazard use)

Safety Alert: Don't DIY Backflow Testing or Backflow Preventer Replacement
Some jobs are too critical for DIY videos and uncalibrated gauges
Backflow occurs when water flows in the wrong direction and contaminated water mixes with clean potable water — something backflow prevention devices are designed to stop. Attempting DIY backflow testing or installing unapproved backflow devices can result in incorrect readings, cross-connection hazards and test reports that your water provider will not accept, putting the community water supply at risk.
- Never remove, bypass or cover a backflow preventer without approval from your water provider and a licensed plumber
- Don't attempt backflow testing without certification and properly calibrated test gauges
- Call a professional immediately if you see active leaks, heavy corrosion or receive a backflow violation notice
