FAQs
What is a backflow assembly and why is it required for commercial properties in Lake City?
A backflow assembly is a mechanical device—such as a Reduced-Pressure Principle Assembly (RP), Double-Check Valve Assembly (DCVA), or Pressure Vacuum Breaker (PVB)—installed on your potable water service line to prevent contaminated water from reversing flow and entering the public supply. Lake City’s municipal plumbing code, which mirrors Florida Administrative Code 62-555 and the national Uniform Plumbing Code, mandates approved backflow prevention on most commercial and industrial connections because these sites often have cross-connections to chemicals, process water, or irrigation systems. Failure to install and maintain an approved device can result in service interruption, fines, or liability if contamination occurs.
What types of complex backflow assemblies do you install, test, and repair?
We handle the full spectrum of commercial assemblies rated ¾″ through 10″, including but not limited to: • Reduced-Pressure Principle Assemblies (RP/RPZ) for high-hazard applications such as medical facilities and chemical plants. • Reduced-Pressure Detector Assemblies (RPDA) for fire sprinkler systems with antifreeze or chemical additives. • Double-Check Valve Assemblies (DCVA) and Double-Check Detector Assemblies (DCDA) for medium-hazard fire protection and irrigation. • Pressure Vacuum Breakers (PVB) and Spill-Resistant Vacuum Breakers (SVB) for dedicated irrigation zones. • Specialty stainless-steel or lead-free assemblies required in food-grade or corrosive environments. Our technicians are ASSE-certified and carry the parts, gauges, and manufacturer training needed to service brands such as Watts, Wilkins, Apollo, Febco, Ames, and Conbraco.
How often must my commercial backflow device be tested and certified in Lake City?
Lake City Utilities requires an initial performance test upon installation and an annual retest thereafter. High-hazard sites—chemical plants, medical labs, breweries, or facilities with boilers—may be placed on a semi-annual schedule at the discretion of the Water Department. After each test, a Form 62-555.360 Backflow Test Report must be submitted within 10 business days. We file this paperwork electronically on your behalf and attach a color-coded test tag to the device so inspectors and insurance auditors can see the compliance date at a glance.
What are the warning signs that my backflow prevention assembly is failing?
Because many failures are internal, they often go unnoticed until a test is performed, but common indicators include: • Continuous discharge or dripping from the relief valve on an RP assembly. • Unexplained pressure loss or inability to maintain sprinkler system pressure. • Visible corrosion, cracks, or freeze damage on the body or test-cock caps. • Water hammer, vibration, or unusual noises when equipment cycles. • Taste or odor changes in potable water, suggesting potential back-siphonage. If you observe any of these conditions, shut down the downstream system if possible and call a licensed backflow tester immediately.
What does a comprehensive commercial backflow service visit include?
1. Pre-inspection: Verify shut-off valve operation and check for proper clearance and drainage. 2. Performance Testing: Attach calibrated differential-pressure test gauges and record readings in accordance with USC-FCCCHR and ASSE 5010 procedures. 3. Documentation: Complete Lake City’s digital Backflow Test Report, including device serial number, size, manufacturer, and test results. 4. Maintenance or Repair (if needed): Replace faulty check springs, rubber seats, O-rings, or relief-valve diaphragms with manufacturer parts; perform hydrostatic retest. 5. Tagging & Certification: Affix tamper-evident tag with pass/fail status, next due date, and technician license number. 6. Customer Review: Provide a copy of the report, discuss any site-specific risks, and recommend freeze protection or enclosure upgrades if relevant.
How do I schedule a test or installation, and what information should I have ready?
Call our Lake City office at (xxx) xxx-xxxx or request service online. Please have the following details handy: • Property name, address, and on-site contact. • Number of assemblies, their sizes, and approximate locations (mechanical room, fire vault, irrigation box, etc.). • Water meter or service account number (helps us coordinate with Lake City Utilities). • Any recent violations or deadline letters from the city. • Site access requirements—gate codes, safety orientation, or after-hours work restrictions. Most tests take 20–45 minutes per device, and we offer same-week emergency slots for failed or leaking assemblies.
