Backflow is water reversing direction, so that a hose, boiler loop or sprinkler system feeds dirty water into the drinking supply. Prevention devices stop that.
Where you need one
- Lawn irrigation, boiler-fed heating, and many commercial and mixed-use connections need a backflow device, because chemicals or stagnant water could otherwise be drawn back into the city supply.
- Toronto runs a backflow prevention program that requires devices and annual testing for certain properties; check whether yours is included.
Clues it is this job
- New irrigation system
- Boiler or hydronic system
- Commercial unit
- Notice from the city
Types of devices
- Screw a vacuum breaker onto the hose bib and a hose lying in a pail of lawn feed can no longer siphon backward.
- Double check valve assemblies and reduced pressure principle assemblies protect higher-risk connections and are installed with isolation valves and test cocks so they can be checked.
Testing
- Testable assemblies need checking by a certified tester, usually every year.
- We connect a test kit to the test cocks, verify each check holds tight and the relief port opens at its specified differential, record the results, and rebuild any assembly that fails with new springs, seats and seals.
A simple vacuum breaker on outdoor taps protects against hose siphoning.
