Backflow Preventer Installation Requirements
Installing a backflow preventer is essential for safeguarding your water supply from contamination. Here are the general requirements and considerations for backflow preventer installation:
-
Compliance with Local Codes and Regulations
- Permits and Inspections: Ensure that the installation complies with local building and plumbing codes. In many areas, including Toronto, a permit is required, and the installation must pass a municipal inspection.
- Licensed Plumber: The installation must be performed by a licensed and certified plumber who is familiar with local regulations and best practices.
-
Appropriate Type of Backflow Preventer
- Assessing the Risk Level: Determine the appropriate type of backflow preventer based on the level of risk. Common types include Double Check Valve Assemblies (DCVA), Reduced Pressure Zone Assemblies (RPZ), and Pressure Vacuum Breakers (PVB).
- Manufacturer Standards: The backflow preventer must meet industry standards, such as those set by the American Society of Mechanical Engineers (ASME) or the Canadian Standards Association (CSA).
-
Correct Placement
- Accessibility: The backflow preventer should be installed in an accessible location for easy maintenance and testing. It must be installed above ground in areas that are protected from freezing temperatures.

- Testing and Inspection:
- Once installed, the backflow preventer must be tested to ensure it is functioning properly. This test is typically conducted by a certified tester.
- Regular inspections and testing are required to maintain compliance and functionality.
- Maintenance:
- Regular maintenance is crucial to ensure that the backflow preventer remains in good working condition. This includes periodic checks and replacement of worn parts.
FAQ about installing a check valve
A backflow preventer stops contaminated or non-potable water from reversing into your clean supply during pressure changes. Many homes, condos, restaurants, irrigation systems, and medical or industrial sites require devices sized to hazard level. For backflow preventer toronto compliance, devices must be installed and tested by a certified plumber and tester, with reports filed to the municipality.
Local code dictates device type (DCVA or RPZ), location (heated, accessible, upstream of branches), isolation valves, unions, supports, and—if RPZ—an approved drain for relief discharge. Clear working space is mandatory, and the device must be tested immediately after installation and annually thereafter. We handle permits, certified testing, tags, and report submission as part of backflow preventer installation requirements.
Typical Toronto ranges depend on pipe size, device type, access, and paperwork. For backflow valve installation cost planning: homes on ¾″–1″ lines often fall around $450–$900 for DCVA, $950–$1,800 for RPZ; suites with tight access trend higher; mechanical-room devices 1½″–4″ can range $2,000–$8,000+. Quotes include initial certified test and compliance filing.
We survey the site, size the device, protect finishes, install isolation valves/unions/supports, set the DCVA or RPZ in an accessible heated location, and perform the first certified test with paperwork. This is full-scope backflow preventer installation, not just device supply.
Annual certified testing is required under the city’s backflow prevention toronto program. We schedule reminders, complete the test, tag the device, and submit reports to keep you compliant.
We got drain clogged in the kitchen sink. I found POM Group on google and call them. They said plumber will come within an hour. When he arrived and checked our kitchen sink drain he said that it all rusted out and needs to be replaced. After plumber cleared drain he replaced all necessary parts of drain. Everything was done professional and clean.
I would like to say thank you to POM Group for responding so quick to our problem.

Principle of Residential Backflow Preventer Installation
During operation, the valve opens and closes under water pressure. With the flow from above, the element opens and closes from below. Therefore, the backwater valve installation detail does not allow wastewater to rise back up in the pipe.
The device unit is made of plastic or metal. There are two spigots – receiving and releasing inside the element. There is a shutoff valve inside the valve, which closes the water in case of a breakthrough. Mainline backwater valve installation is carried out in any position. The main thing is that the arrow coincides with the flow of wastewater. In general, a residential backflow preventer installation on the main water line entering the home should be accessible for maintenance and inspection.

What is Backflow Prevention?
Backflow Prevention refers to the system or devices used to stop contaminated water from flowing back into clean water supply lines. Backflow can occur due to changes in water pressure, such as during a water main break or heavy usage, causing water from industrial, commercial, or even sewer systems to reverse direction and potentially contaminate drinking water.
Key Features:
- Utilizes a Backflow Preventer, a mechanical valve installed in the plumbing system.
- Ensures water flows in only one direction — from the municipal supply into the property.
- Required by plumbing codes for many types of commercial properties, especially where there’s a risk of contamination (restaurants, medical facilities, industrial buildings).
- Regular testing and certification are often mandated by city bylaws, including in Toronto.
In condos and high-rise buildings, backflow prevention is particularly important due to the shared water systems and the complexity of multi-unit plumbing networks. Proper installation helps maintain safe, clean water for all residents.
