Backflow Testing

A backflow test is a certified inspection of your backflow prevention device. During the test, a licensed plumber connects specialized gauges to the device to measure pressure levels and confirm that the internal valves are functioning properly.

The test confirms that the device can prevent contaminated water from entering the clean water system.

Once the test is complete, a report is generated and submitted to your local water authority to confirm compliance.

A backflow prevention device is installed on your water system to stop contaminated water from flowing backward into the clean public water supply.

Backflow can occur when there is a sudden change in water pressure, which can allow harmful contaminants such as chemicals, bacteria, or debris to enter the drinking water system.

Backflow preventers are commonly installed on:

• Irrigation systems
• Commercial buildings
• Fire sprinkler systems
• Multi-unit residential properties
• Industrial and commercial plumbing systems

Regular testing ensures the device is working properly and keeping your water safe.

Backflow preventers must be tested by a licensed and certified professional using specialized testing equipment.

The process includes:

1. Shutting off the water supply temporarily
2. Connecting testing gauges to the backflow device
3. Measuring pressure levels across internal valves
4. Verifying the device prevents reverse water flow
5. Completing compliance documentation

DIY testing is not permitted because certified reporting is required by local jurisdictions.

If a device fails testing, it must be repaired or replaced to remain compliant.

Backflow testing costs vary depending on the type and location of the device.

Typical cost ranges:

• Residential backflow testing: $75 to $150
• Commercial backflow testing: $150 to $300+ depending on system size

Testing is fast, affordable, and helps prevent costly problems and compliance issues.

Most water authorities require annual backflow testing.

You may receive a notice from your local jurisdiction reminding you when testing is due.

We can help you schedule testing and remain compliant.

If your backflow preventer fails testing, we can repair or replace the device and retest it to ensure compliance.

We handle the entire process, including submitting updated documentation to your water authority.
