FAQs
What is backflow and why is prevention essential for commercial properties in Kingston?
Backflow is the unwanted reversal of water flow that can allow contaminants—such as chemicals, cleaning agents, or bacteria—from a commercial plumbing system to enter the municipal drinking-water supply. Kingston’s water utility follows Ontario Building Code and CSA B64 standards, which require every medium- and high-hazard commercial property to install and maintain a certified backflow prevention device. Proper prevention protects public health, keeps your business compliant with local bylaws, and avoids costly shutdowns or fines.
Which types of backflow prevention devices are typically required for commercial buildings?
The device required depends on the hazard level and plumbing configuration of your facility. Common options include: • Double Check Valve Assembly (DCVA) – for low-to-medium hazard systems such as most office buildings. • Reduced Pressure Zone Assembly (RPZ) – for medium-to-high hazard environments like restaurants, laboratories, manufacturing plants, and medical facilities. • Pressure Vacuum Breaker (PVB) or Spill-Resistant Vacuum Breaker (SVB) – often used on dedicated irrigation systems. Our certified testers assess your site, determine the correct device under CSA B64 and Utilities Kingston rules, and handle permitting and installation.
How often do backflow preventers need to be tested and certified in Kingston?
All testable backflow devices in commercial properties must be tested when first installed, immediately after any repair or relocation, and at least once every 12 months thereafter. Kingston’s Cross-Connection Control Program requires the annual test report to be completed by a licensed plumber who is a registered B64 tester and submitted to the city within 30 days of the test date.
What does a professional backflow test and inspection involve?
1. Shut-off valves are closed, gauges are attached, and the assembly is isolated. 2. Differential pressure readings are taken across each check valve to confirm they close at the required pressure. 3. The relief valve (for RPZs) is assessed to ensure it opens before pressure drops to an unsafe level. 4. Test results are documented on an approved form, noting device make, model, serial number, and any deficiencies. 5. If the device fails, on-the-spot cleaning or repair is performed where possible; otherwise, a repair quote is provided. 6. A signed test certificate is submitted electronically to Utilities Kingston and a copy is left onsite for your records.
What are the consequences of non-compliance with Kingston’s backflow prevention regulations?
Failure to install, maintain, or annually test a required device can result in: • Fines under the City of Kingston Water Bylaw, which may exceed $5,000 per offence. • Immediate water service interruption until compliance is achieved, leading to operational downtime. • Liability for any contamination event traced back to your premises, including cleanup costs and potential civil action. Keeping devices current not only avoids penalties but also demonstrates due diligence to employees, customers, and regulatory bodies.
