Why Backflow Prevention Matters for Every Property
When water moves in the wrong way within your plumbing system, it can cause backflow, which pushes tainted water in the direction of the municipal drinking water system. This can happen due to back pressure, back siphonage, or a sudden drop in water pressure, and it puts your drinking water supply at risk.
A proper backflow prevention device blocks hazards from entering your potable water systems. Cross-connection control and backflow prevention requirements of Ontario mandate that you maintain, test, and install permitted devices to safeguard the municipal water distribution system, regardless of whether you own a residential property, commercial structure, or institutional facility. Implementing a backflow prevention program is one of the most important actions a property owner can take to prevent contamination and keep their plumbing system safe.
