- Plumbing FAQs
Common Commercial Plumbing Questions from Illinois Property Owners
Running a commercial property in Illinois comes with unique challenges. From state code compliance to emergency maintenance, we answer the top questions business owners and facility managers ask to keep their operations running smoothly.
A backflow preventer is a specialized valve that ensures water flows in only one direction—from the municipal supply into your building. It prevents “contaminated water” (containing chemicals, waste, or bacteria) from flowing backward into the clean public water supply due to pressure changes. Local and federal “safety compliance solutions” require these devices to protect public health. Without one, your facility risks causing a contamination event and facing severe legal penalties.
In Illinois, state plumbing codes and the EPA typically require annual testing for all commercial backflow prevention assemblies. This test must be performed by a state-licensed Cross-Connection Control Device Inspector (CCCDI). Regular testing ensures the internal seals and springs are functioning correctly. Failure to submit your annual test report can result in fines or the disconnection of your water service.
While costs depend on the valve size and accessibility, a standard commercial backflow test typically ranges from $100 to $250 per device. Facilities with multiple devices often qualify for volume discounts. Cardinal Plumbing Co. offers transparent pricing and “maintenance that saves you money” by locking in a flat rate with our annual compliance agreements, ensuring you never face surprise fees.
If your device fails, it must be repaired or replaced immediately to maintain compliance. Do not panic—Cardinal Plumbing Co. carries repair kits for all major brands. Our technicians can often clean the internal components or replace worn rubber parts on the spot. If a complete replacement is needed, our 24/7 emergency response team works quickly to install a new unit, minimizing downtime and ensuring your water service remains uninterrupted.
No. Backflow testing and installation require specialized ASSE certification and calibrated equipment. It is illegal for an unlicensed individual to perform these tests for compliance purposes. Cardinal Plumbing Co. provides “certified technicians” who understand the complex “commercial integration” of these systems. We handle all the paperwork and submit the certification directly to the municipality on your behalf, providing you with “total peace of mind.”
