Backflow Prevention

Backflow occurs when the normal flow of water in piping systems is reversed, which can lead to contaminants entering the clean water supply. This typically happens due to changes in pressure within the system, such as a sudden drop in water pressure caused by firefighting activities or a significant break in a water main.

In Clearfield, UT, the concern is significant due to the city’s fluctuating pressures in water lines caused by varying elevations and the presence of numerous industrial and agricultural activities. The risk is that contaminants from systems like irrigation, industrial fluids, or even chemicals from fire suppression systems could backflow into the public water system, posing health risks.

The city mandates the installation of backflow prevention devices on irrigation systems, fire sprinkler systems, and any connection where potable and non-potable water systems could intersect. Property owners are required to have these devices tested annually by a certified backflow tester to ensure they function correctly and protect the water supply effectively.

The most common backflow prevention devices used in Clearfield include the Reduced Pressure Zone (RPZ), Pressure Vacuum Breaker (PVB), and Double Check Valve (DCV). Each serves a specific purpose and is suited to different types of potential contamination risks.

RPZs are considered the most secure form of backflow prevention. They are installed in situations where the risk of contamination is high, such as in hospitals or chemical plants. RPZs have an internal mechanism that dumps out water when backflow is detected, preventing any reversal of flow back into the main water supply.

PVBs are typically used in sprinkler systems and outdoor water fixtures. They include a spring-loaded check valve that closes automatically if water pressure drops, as well as an air inlet valve that opens to break the suction, preventing water from flowing backward.

DCVs are used where the hazard is considered low to moderate. They consist of two independently operating check valves joined by a chamber that allows the assembly to drain. They are often used in residential properties where the main risk is from sources like domestic storage tanks and hose connections.

These devices are crucial in preventing the potential mix of polluted water from private sources into the municipal water system, thus ensuring that the water remains safe for consumption.

If you suspect a backflow issue at your property in Clearfield, it’s crucial to act immediately to mitigate any risks of water contamination:

Cease using water: Stop using any water to avoid pulling more contaminated water into your property.

Contact a certified professional: Reach out to a certified backflow prevention specialist who can assess the situation and test your backflow prevention device. Clearfield city maintains a list of certified testers.

Notify the water utility: Inform the Clearfield City Water Department about the issue. They can provide guidance and may need to take broader measures if the problem extends beyond your property.

Check for updates: Sometimes, backflow issues can result from city-wide pressure changes or maintenance work. The city’s utilities department may provide updates if the issue is widespread.

Immediate attention to suspected backflow issues is essential for your safety and that of the community. Regular maintenance and annual checks of backflow prevention devices can preempt many problems.

Preventing backflow issues requires a proactive approach, including regular maintenance and awareness of the system’s operation:

Regular inspections and maintenance: Ensure that your backflow prevention devices are tested and maintained annually by a certified professional. This is not only a safety measure but also a regulatory requirement in Clearfield.

Understand your system: Knowing where your backflow preventers are located and how they work can help you identify any potential malfunctions before they cause serious issues.

Landscaping and outdoor maintenance: Be mindful of where you plant deep-rooted trees and how you use water outside. Irrigation systems are a common source of backflow issues if not properly maintained.

Educate yourself on local regulations: Stay informed about Clearfield’s specific water safety regulations and requirements for backflow prevention, especially if you have a commercial property or use substances that could contaminate the water supply.
