Backflow Prevention Services

Understanding Backflow Prevention in Western Pennsylvania

Backflow prevention is a critical component of public water system safety. A backflow preventer is a mechanical device that prevents contaminated water from flowing backward into the clean water supply. Without proper backflow prevention, potential contaminants from irrigation systems, boilers, industrial processes, or other sources could enter your drinking water, posing serious health risks. DeMonte Contracting specializes in all aspects of backflow prevention for properties throughout Allegheny County, Westmoreland County, Butler County, Armstrong County, and Washington County.

When is Backflow Prevention Required?

Most municipalities and water authorities in Western Pennsylvania require backflow prevention devices in certain situations. Common scenarios requiring backflow preventers include properties with irrigation or lawn sprinkler systems, homes or businesses with boilers or radiant heating systems, commercial kitchens and restaurants, medical and dental facilities, car washes and commercial cleaning operations, industrial facilities with process water, swimming pools and hot tubs, fire sprinkler systems, and properties with wells or auxiliary water sources. If you're unsure whether your property needs backflow prevention, DeMonte Contracting can assess your situation and provide expert recommendations based on local requirements.

Types of Backflow Prevention Devices

Several types of backflow prevention devices are used depending on the level of hazard and specific application. Reduced Pressure Zone (RPZ) valves provide the highest level of protection and are required for high-hazard applications. These devices have two independent check valves with a relief valve between them that discharges water if either check valve fails. Double Check Valve Assemblies provide good protection for moderate hazards with two check valves in series. Atmospheric Vacuum Breakers are simple devices used for low-hazard applications like irrigation systems. Pressure Vacuum Breakers combine a check valve and vacuum breaker for irrigation and hose bib protection. Our certified technicians can recommend and install the appropriate type of backflow preventer for your specific needs.

Annual Backflow Testing Requirements

Most water authorities require annual testing of backflow prevention devices to ensure they're functioning properly. Pennsylvania law requires that backflow testing be performed by certified testers. DeMonte Contracting's certified technicians perform comprehensive testing following approved procedures. During testing, we check the shut-off valves, test cocks, relief valve, check valves, air inlet valve (if present), and overall assembly performance. We measure differential pressures and verify the device operates within acceptable parameters. If the device fails testing, we identify the problem, make necessary repairs, and retest to ensure compliance. All test results are documented on official forms and submitted to your water authority.

Backflow Preventer Installation Services

Installing a backflow prevention device requires expertise to ensure proper operation and code compliance. DeMonte Contracting handles the complete installation process. We determine the correct type and size of device needed, obtain necessary permits from your municipality, install the backflow preventer in an accessible location meeting code requirements, perform initial testing and certification, and file required documentation with your water authority. For irrigation systems, we typically install backflow preventers at the point where the irrigation system connects to your main water supply. For buildings with boilers or other potential hazards, we install devices on the building's main water service line.

Common Backflow Preventer Problems

Backflow prevention devices can develop problems over time, especially in areas with hard water or freezing temperatures. Common issues include leaking relief valves, which may indicate a failed check valve or debris in the system; frozen and burst devices from inadequate winterization; failed check valves that don't close properly allowing backflow; stuck test cocks that prevent proper testing; and deteriorated rubber components that need replacement. DeMonte Contracting repairs all types of backflow preventer problems. We stock common replacement parts and can often complete repairs the same day your device is tested.

Compliance with Local Water Authority Requirements

Different water authorities have specific requirements for backflow prevention. Pittsburgh Water and Sewer Authority (PWSA), Municipal Authority of Westmoreland County (MAWC), Pennsylvania American Water, and other water providers each have their own backflow prevention policies and reporting requirements. DeMonte Contracting is familiar with the requirements of all major water authorities in Western Pennsylvania. We ensure your backflow preventer installation and testing meets all applicable requirements, and we handle filing test reports with the appropriate authority. This ensures you remain in compliance and avoid potential fines or water service interruptions.

Protecting Your Family and Business

Beyond meeting legal requirements, backflow prevention is about protecting health and safety. Contaminated water entering the drinking water supply can cause serious illness. For businesses, especially restaurants, medical facilities, and schools, proper backflow prevention is essential for protecting customers, patients, and students. DeMonte Contracting takes backflow prevention seriously. Our careful installation, thorough testing, and prompt repairs ensure your backflow preventer provides reliable protection year after year.
