At C & D Plumbing Inc., our state-licensed master plumbers are certified backflow inspectors who handle the entire compliance tracking cycle with ultimate precision. We perform accurate pressure differential field testing, complete structural check-valve restorations, and submit all required compliance documentation directly to your city water department, protecting your business from costly citations and surprise water service shutoffs.

Protecting Clean Water and Safeguarding Corporate Assets

Streamlined Cross-Connection Controls to Keep Your Operation Legally Sound

Backflow assemblies are critical mechanical gatekeepers that prevent non-potable liquids, chemicals, and wastewater from siphoning backward into your municipal clean water network during unexpected mainline pressure drops. Because these assemblies contain moving internal discs, seals, and spring-loaded springs, normal mechanical wear can cause components to fail over time. Our dedicated commercial team eliminates the administrative burden of water safety tracking by executing precision diagnostics and filing immediate digital validation certificates on your company's behalf.

Solution A: Certified Cross-Connection Field Testing & Certification

Our core compliance service satisfies all strict local and state environmental laws. A certified technician utilizes calibrated digital test kits to verify that all internal check valves, air gaps, and relief ports maintain the exact required pressure parameters to isolate municipal lines perfectly.



• Best suited for: Commercial building owners, property managers, shopping centers, and warehouse facilities needing to satisfy their mandatory annual city or county water compliance deadlines.

Solution B: Precision Backflow Assembly Rebuilding & Repairs

If an assembly fails its initial differential test, our trucks arrive fully stocked with original equipment manufacturer (OEM) replacement kits. We replace worn rubber gaskets, internal springs, and corroded check valves immediately to bring your device back into peak functional compliance.



• Best suited for: Facilities dealing with aging cross-connection devices that fail local safety parameters, avoiding the steep capital costs of complete utility line excavation and total system replacements.
