FAQs
What is backflow and why is it a concern for commercial properties in McDonald?
Backflow is the unwanted reversal of water flow that can allow contaminants—such as chemicals, oils, and bacteria—to enter the potable water supply. Commercial buildings in McDonald often have complex plumbing systems with fire-sprinkler lines, boilers, and industrial equipment that increase the risk of back-pressure or back-siphonage. A properly installed and maintained backflow prevention device protects your occupants, the public water main, and your business from health hazards and costly shutdowns.
Are backflow prevention devices required by law for my McDonald business?
Yes. The Pennsylvania Department of Environmental Protection (DEP), Allegheny County Health Department, and the Borough of McDonald each adopt regulations that mandate approved backflow prevention assemblies on commercial properties where a cross-connection could exist. In most cases, annual testing by a certified backflow tester must be documented and submitted to the local water authority. Failure to comply can lead to fines, water service interruption, or refusal of occupancy permits.
How often do backflow preventers need to be tested and certified in McDonald?
Most commercial backflow assemblies must be tested once every 12 months. Certain high-hazard facilities—restaurants, medical offices, car washes, and manufacturing plants—may be required to test more frequently, especially after device repair, relocation, or a change in water service. Our licensed testers will provide the official test report forms that the McDonald Municipal Authority or Pennsylvania American Water require.
What types of backflow prevention devices are commonly used in commercial buildings?
The most common devices we install and service include: • Reduced Pressure Zone (RPZ) Assemblies – required for high-hazard applications such as chemical processes and irrigation systems. • Double Check Valve Assemblies (DCVAs) – used on low- to medium-hazard potable water lines. • Pressure Vacuum Breakers (PVBs) – typically installed on lawn-irrigation systems. • Spill-Resistant Vacuum Breakers (SVBs) – suited for indoor installations where water discharge must be minimized. The choice depends on hazard level, pressure conditions, and local code requirements.
What happens during a professional backflow test and how long does it take?
A certified technician will: 1. Obtain any necessary permits or access clearances. 2. Shut off downstream valves to isolate the device. 3. Attach calibrated test gauges to each test cock. 4. Measure check-valve and relief-valve performance to verify that they hold the required pressures. 5. Record results, make minor adjustments if allowed, and tag the device with the date and tester ID. 6. Submit the completed test report to the governing authority on your behalf. Most tests take 20–40 minutes per device, causing minimal disruption to water service. If the unit fails, we will provide repair or replacement options immediately.
