Backflow Preventer Testing in Burlington

What a backflow preventer does

Many commercial buildings have equipment that could push water back toward the public main: boilers, fire sprinkler systems, carbonators, irrigation lines and process equipment. A backflow preventer is a valve assembly on the service line or at the equipment that only lets water travel one way. Testing proves the check valves and relief valve inside it still close properly.

Who usually needs testing

• Restaurants with soda carbonators and coffee equipment
• Buildings with fire sprinkler connections
• Properties with lawn irrigation systems
• Dental and medical clinics
• Industrial units with process water or chemical dosing
• Multi-unit buildings with boilers on the domestic line

What the test involves

1. We confirm the device type: double check, reduced pressure or vacuum breaker
2. Water is shut down briefly and the gauge hoses go onto the device's test ports
3. Our differential gauge reads both checks and the point where the relief port opens
4. Results are recorded on the test form with the device serial number
5. Water is restored and the device is checked for leaks

When a device fails

• Debris on the check valve seats is cleaned and the device is retested
• Worn rubber parts and springs are replaced with a repair kit
• Devices that cannot be repaired are replaced and tested on install

Halton Region requirements

Halton Region runs a cross-connection control program that has required many commercial, industrial and institutional properties to install backflow prevention and submit test results each year. Deadlines and forms change, so check the current terms with the Region or the notice you received. We record results in the format the program asks for.
