What is backflow?

Backflow is the unwanted reversal of water flow in a plumbing system, which can allow contaminated water to enter the clean water supply.

Why is backflow prevention important?

Backflow prevention protects drinking water from contaminants like pesticides, chemicals, and bacteria. Without proper prevention, harmful substances could be drawn into the potable water system.

What causes backflow?

Backflow usually occurs due to:

• Backsiphonage: when water pressure drops and contaminated water is siphoned into the clean system.

• Backpressure: when pressure in a non-potable system (like a boiler or irrigation system) is greater than the public water supply pressure.

What is a backflow preventer?

A backflow preventer is a mechanical device installed in a plumbing system to stop contaminated water from flowing back into the clean supply. Common types include double-check valves, pressure vacuum breakers, and reduced pressure zone assemblies.

Do I need a backflow preventer?

Yes, if your property has irrigation systems, fire sprinklers, or other plumbing connections that could introduce contaminants. Many municipalities require them by law for certain buildings.

How often should backflow devices be tested?

Most local regulations require annual testing by a certified backflow tester to ensure the device is working properly.

Who can test a backflow preventer?

Only licensed and certified backflow testers are authorized to perform the test, and they usually provide documentation to submit to your local water authority.

What happens during a backflow test?

A certified tester:

1. Shuts off water to the system briefly.

2. Uses specialized gauges to check valves and pressure.

3. Ensures the device prevents reverse flow properly.

4. Provides a test report for compliance records.

What if my backflow device fails the test?

If it fails, Gunter Backflow Services, LLC. can repair or replace your device to comply with regulations and to protect the water supply.

What are the penalties for not testing backflow preventers?

Penalties vary but can include fines, water service shutoff, or non-compliance notices from your local water provider.
