Get Canada Annual Backflow Preventer Test Report - City Of Chilliwack 2023-2024

Critical check valves are inspected/tested using three main methods: externally, internally and, in unique situations, in-line function testing.

To ensure functionality, it is generally recommended to have your backflow prevention devices inspected every year. It is important to note that the NFPA 25 Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems requires periodic testing of backflow systems.

When a backflow prevention device fails, it allows water from the non-potable sources, such as irrigation systems or industrial processes, to flow back into the public water supply. This can result in the contamination of the drinking water with harmful substances, bacteria, or chemicals.

Most backwater valves come with a see- through top. This way, the valve can easily be inspected to see if there are any clogs from debris or if the valve is otherwise not functioning properly. It's always a good idea to schedule a qualified plumber to handle the annual inspection and maintenance.

Installation of backflow preventers is required under Section 7 of the Ontario Building Code and the Ministry of Environment, Conservation and Parks expects the Town to implement a backflow prevention program. This is considered to be a necessary industry best practice.

Vancouver Water Works created bylaw 4848, stating that all backflow preventers must be tested every year by a certified backflow tester.

First, the number 2 shut off valve on the backflow is turned off. A test kit is placed on the device. The test kit uses the water left in the backflow. Once the test is complete, the kit is removed, and the water is turned back on slowly, which prevents pressure surges from occurring.

Dip In Water Pressure If your backflow device starts malfunctioning, you'll experience increased water levels or a visible drop in the water pressure in your water system around the house, including kitchen faucets, showerheads, and bathroom sinks.
