What this job involves
Backflow means water travelling backwards: out of a lawn sprinkler line, a boiler loop or a treatment unit and into the pipes that feed your kitchen tap. A pressure dip in the street main, or a pump inside the house, can set it off. Preventers, from the little vacuum breaker on a hose bib to testable double-check assemblies, keep it from happening.
How the job goes
- List every cross-connection: irrigation, boiler feed, softener, hose bibs.
- Match a device to each hazard level.
- Install with room left for testing and service.
- Test the assembly where the rules call for it.
- Record device details for future checks.
Warning signs on your pipes
- An in-ground sprinkler system waters the lawn.
- A hydronic boiler is topped up from the house supply.
- Hose bibs have no vacuum breakers.
- A treatment system was added recently.
- The Region has asked about cross-connection control.
From the job notes
Sprinkler systems are the most common residential backflow concern in Oakville, especially on larger lots.
Sprinkler systems are the most common residential backflow concern in Oakville, especially on larger lots. Fertilizer and stagnant water sitting in sprinkler lines should never reach a glass of drinking water.
A testable assembly gets its periodic check from a certified backflow tester, not from us by default. Confirm what Halton Region currently requires for your type of property.
