What Is Annual Backflow Testing?

Annual backflow testing is a mandatory requirement across Ontario municipalities to ensure your backflow prevention devices are functioning properly. Under various municipal bylaws including Toronto Water Supply By-law, Peel Region By-law 10-2017, York Region requirements, and Hamilton By-law 10-103, property owners must have their backflow prevention devices tested annually by an OWWA certified tester.

Backflow prevention devices protect the municipal water supply from contamination by ensuring water flows in only one direction. When these devices fail, contaminated water can flow backward into the clean water supply, creating serious health hazards. Annual testing verifies that your devices are working correctly and provides documentation to your municipality proving compliance.

                ⚠️ Important: Failure to complete annual backflow testing can result in fines ranging from $500 to $10,000, and municipalities may disconnect water service for non-compliant properties. Most municipalities send compliance notices 30-60 days before your annual testing deadline.
            

Our Annual Testing Process

Our certified technicians follow strict OWWA and CSA B64.10.1 standards to ensure accurate, reliable testing:

1. Pre-Test Inspection

We inspect the device location, check for visible damage, verify shut-off valves are accessible, and ensure the device is properly labeled with manufacturer information and installation date.

2. Performance Testing

Using calibrated test gauges, we perform comprehensive functional tests including check valve operation, relief valve activation, and pressure differential measurements specific to your device type.

3. Results Documentation

We complete detailed test reports including device specifications, test results, and pass/fail status. All documentation meets municipal reporting requirements.

4. Municipal Filing

We submit test reports directly to your municipality within their required timeframe (typically 14-30 days). You'll receive confirmation of submission and compliance.

5. Reminder Service

We automatically schedule your next annual test and send reminders 60 days before your due date, ensuring you never miss a deadline.

6. Repair Coordination

If your device fails testing, we provide immediate repair or replacement options and expedited re-testing to minimize downtime.

Frequently Asked Questions

Ontario municipalities require annual backflow testing once every 12 months. Your specific testing month may be assigned by your municipality, or you can choose any month. We recommend scheduling well in advance of your due date to avoid compliance issues.

What happens if my device fails testing? +

If your device fails testing, you typically have 30 days to repair or replace it and schedule a re-test. We provide immediate repair or replacement services and can often complete repairs the same day. A failed device must be brought into compliance before the municipality will accept your annual report.

How long does backflow testing take? +

A typical backflow test takes 30-60 minutes per device. Factors affecting time include device accessibility, device type, and whether any repairs are needed. We schedule appointments with arrival windows and respect your time.

Do you submit reports to the municipality? +

Yes! We file all test reports directly with your municipality within their required timeframe. You'll receive a copy of the report for your records and confirmation when the report has been submitted. This ensures your property remains in good standing.

What certifications do your technicians have? +

All our technicians hold OWWA (Ontario Water Works Association) Cross Connection Control Specialist certification. They are also licensed plumbers or hold equivalent trade certifications. Our certification is current and recognized by all Ontario municipalities.
