Toronto Backflow Testing Requirements & Compliance

This program exists to protect the public drinking water system from contamination caused by backflow events.

If you own or manage an industrial, commercial, institutional, or Part 3 residential property in Toronto, annual backflow preventer testing is not optional.

Under the City’s Backflow Prevention Program, qualifying properties are legally required to have their backflow prevention devices tested every year by a certified tester, with results submitted to Toronto Water.

Who Is Required to Have Annual Backflow Testing?

You are required to comply if your property falls under any of the following categories:

  • Commercial buildings (restaurants, retail, offices, plazas)

  • Industrial facilities and warehouses

  • Institutional buildings (schools, medical, municipal)

  • Part 3 residential properties as defined by the Ontario Building Code

  • Any property with a backflow prevention device installed as part of a cross-connection control program

If you have received a notice from the City or have previously completed a backflow test, annual testing is mandatory.

Protecting Toronto's Drinking Water Systems

How Often Is Backflow Preventer Testing Required?

  • Testing is required once every 12 months

  • Each backflow preventer on the property must be tested individually

  • Newly installed or replaced devices must be tested immediately after installation

  • Test results must be submitted within the City’s required timeframe

Missing or late submissions can result in compliance notices and follow-up enforcement.

What Happens If You Don’t Comply?

Failure to complete annual backflow testing may lead to:

  • Written compliance notices from the City

  • Escalation to enforcement actions if unresolved

  • Potential service restrictions until compliance is achieved

These are administrative outcomes, not scare tactics. The intent is to ensure public water safety through verified testing and documentation.

If a Backflow Preventer Fails Testing

If your annual inspection results in a failed backflow test, corrective action is required before your property can be brought back into compliance.lowing categories:
Depending on the condition of the device, this may involve:

  • Backflow device repair to address worn seals, valves, or internal components

  • Backflow valve replacement when a device no longer meets performance or code requirements

  • Full backflow preventer replacement in Toronto for outdated, damaged, or non-compliant assemblies

All repaired or replaced backflow preventers must be retested and documented before results can be submitted.
Our team handles the repair, replacement, and retesting process to ensure your system meets City requirements and compliance is restored without unnecessary delays.

Understanding Back flows Valves

Back Pressure

Back pressure occurs when pressure in a private water system is greater than pressure in the City’s water supply system. This can result in water from the private system forcing its way into the City’s distribution system and can be caused by pumps, elevated tanks, temperature increases in boiler systems, and other local pressure events.

Back Siphonage

Back siphonage occurs when pressure in the City’s water supply system is lower than pressure in a private system. It can pull contaminated water from the private water system into the City’s distribution system and can be caused by nearby fire-fighting or water main breaks.

The main difference lies in their level of protection.

RP assemblies are generally recommended for higher-risk applications where there is a significant risk of contamination.
Backflow refers to the undesirable reversal of water flow, allowing contaminated water to enter the clean water supply system.

A Cross-Connection Control Survey is a systematic evaluation aimed at identifying and addressing potential cross-connections within water distribution systems. These cross-connections could lead to the contamination of the clean water supply if backflow occurs, allowing non-potable water to enter the drinking water system. Trained professionals inspect properties and plumbing systems to spot instances where safe and contaminated water could mix. The goal is to eliminate or mitigate these risks through measures like installing backflow prevention devices and ensuring proper plumbing practices, thus ensuring the safety and quality of the drinking water supply.

Yes, it is generally mandatory to test a newly replaced Backflow Preventer Device. Testing ensures the device functions correctly, prevents backflow, and maintains water supply safety.
