A backflow assembly stops water inside a property, from its boiler, its irrigation or its process equipment from siphoning back into the city main. For years Toronto has made a broad range of business and institutional sites fit one of these assemblies and get it tested once a year.
Who needs a backflow device
- The City of Toronto backflow prevention program has applied to a wide range of non-residential properties, from restaurants and clinics to factories, plazas and apartment buildings with boilers or fire lines.
- The device type depends on the hazard.
- Toronto Water can confirm what applies to your site today.
When to ring us
- City paperwork landed asking for the results of this year
- Steady discharge out of the RP relief vent
- Pressure dropping on upper floors after a device was added
- A device installed years ago with no test record
What the yearly test involves
- A certified tester hooks a differential gauge kit onto the test ports on the device, confirms both checks seal, and watches the relief port open at its rated point.
- The water supply is interrupted only for a short time.
- If the device fails, we tell you which part failed before replacing anything.
Repairs and replacements
- Failed tests usually trace back to grit lodged under a seat, a weak spring, or a torn rubber diaphragm.
- A rebuild kit usually puts it right.
- Older devices that are no longer supported, or that are the wrong type for the hazard, are replaced and tested again before we leave.
