Backflow Device Tests for Business Water Services

Spots in a building where these assemblies sit

• Right after the meter on most business water services
• On fire sprinkler connections
• On boiler feeds, carbonators and chemical dispensers
• On irrigation lines for plazas and buildings

Signs a device is failing

• The RP relief port dribbling or dumping water onto the floor
• A test overdue on the purveyor notice
• Pressure drops in the building after the device
• Visible corrosion or leaks at the test cocks

How a test is done

1. The device type and size are recorded from the body
2. Downstream water is shut so the building is briefly without supply
3. Our differential gauge hoses go onto the numbered test cocks
4. First check, second check, then relief opening point: each one read and logged
5. Water is restored and the result recorded

If it fails

• Rubber parts and springs are replaced from a repair kit
• The device is retested after the rebuild
• Damaged or obsolete bodies are replaced with an approved device
• A new device may need a permit; we will tell you before work starts

Brampton's water is supplied through the Region of Peel, which runs the cross-connection control programme. Requirements and forms change, so check the Region's current rules for your building.

Ready when you are. One call, a real plumber, an arrival window.
