FAQs
What is backflow and why is it a concern for commercial properties in Gruetli-Laager?
Backflow occurs when the normal direction of water in a plumbing system is reversed, allowing contaminated or non-potable water to flow back into the public water supply. Commercial buildings in Gruetli-Laager typically have complex plumbing systems that connect to boilers, irrigation lines, fire-sprinkler systems, and industrial equipment—all of which can create cross-connections and potential back-pressure or back-siphonage situations. If backflow happens, chemicals, bacteria, or other pollutants could enter the municipal water lines, posing a serious health risk and leading to fines or shutdowns from local authorities.
Are backflow prevention devices required by code in Gruetli-Laager and the State of Tennessee?
Yes. The Tennessee Department of Environment and Conservation (TDEC) and most local water utilities, including those serving Gruetli-Laager, mandate that all commercial facilities with potential cross-connections install approved backflow prevention assemblies. Businesses such as restaurants, medical offices, manufacturing plants, car washes, and multi-story buildings must have backflow devices that meet ASSE and USC-FCCCHR standards. In addition, these devices must be tested annually by a state-certified tester, and the test results must be submitted to the local water authority.
How often do I need to test and certify my commercial backflow preventer?
In Gruetli-Laager, backflow assemblies in commercial properties must be tested at least once every 12 months, or more frequently if required by the local water utility, changes in system use, or after any repair or relocation of the device. The test must be performed by a licensed, TDEC-approved backflow prevention tester. Documentation of the test results must be submitted to the utility within the time frame specified—usually 30 days—to maintain compliance and avoid penalties or service interruptions.
What types of backflow prevention assemblies are commonly used in commercial facilities?
The four most common assemblies are: (1) Reduced Pressure Zone (RPZ) assemblies, ideal for high-hazard applications such as medical, chemical, or food-processing facilities; (2) Double Check Valve Assemblies (DCVAs), used for low- to moderate-hazard situations like office buildings or apartment complexes; (3) Pressure Vacuum Breakers (PVBs), typically installed on irrigation systems; and (4) Spill-Resistant Vacuum Breakers (SVBs), a specialized version of PVB designed for indoor or confined spaces. Our technicians assess your site’s specific hazards, water pressure, and plumbing layout to recommend the right device.
What is included in a professional backflow prevention inspection and maintenance visit?
A certified technician will: 1) visually inspect the device for leaks, corrosion, or unauthorized modifications; 2) shut off downstream water and connect calibrated test gauges to verify check-valve and relief-valve performance; 3) record inlet pressure, check valve differential, and relief valve opening readings to ensure they meet manufacturer and ASSE standards; 4) clean or replace rubber seals, springs, or seats if needed; 5) restore the water service, purge air, and confirm proper flow; and 6) complete and submit the official test report to the water utility while providing you with a copy for your records.
