What Backflow Testing Is and Why It Matters
Backflow happens when water flows in the wrong direction through your plumbing system, pulling contaminants back into your clean water supply. This can introduce fertilizers, pesticides, sewage, or other harmful substances into the water your family drinks and uses every day.
Backflow testing is the process of inspecting and verifying that your backflow prevention device is working correctly. A certified tester checks the device under pressure to confirm it stops reversed water flow as intended. Without regular testing, a failing preventer can go unnoticed until a serious health or safety issue arises.
How to Tell If Your Property Is Due for Backflow Testing
Most homeowners do not think about backflow prevention until something goes wrong. Here are common signs that testing may be overdue:
- Annual test date passed
- Discolored tap water
- Odd taste or smell
- Recent irrigation system work
- New backflow preventer installed
- Received a compliance notice
Our Certified Backflow Testing Process
Our certified technician arrives on time, locates your backflow prevention assembly, and shuts off downstream water to isolate the device. Using calibrated differential pressure gauges, we test each check valve and relief valve to confirm the unit is holding pressure and functioning properly.
If the device passes, we complete your test report and submit documentation to your local water authority. If repairs or a replacement are needed, we walk you through your options clearly before any work begins. You will never be handed a bill for something you did not understand or approve of first.
Local Backflow Compliance Requirements
Matthews, NC, follows the state’s water quality and backflow prevention standards, which local water providers enforce. Most commercial properties and irrigation systems connected to the public supply are required to have a certified backflow test completed annually.
Matthew’s summers bring heavy humidity and frequent irrigation, increasing the risk of pressure fluctuations and backflow events in residential and commercial systems alike. Keeping your preventer tested and documented is not just a compliance matter here. It is a practical safeguard during the months your outdoor water systems see the most demand.
If you have received a notice from your water provider or simply are not sure when your last test was completed, we can help you get back on track quickly.

Frequently Asked Questions
How often does backflow testing need to be done?
Most properties are required to have backflow testing completed once a year. Your local water authority or a notice from your provider will confirm your specific schedule.
What happens if my backflow preventer fails the test?
We will explain exactly what failed and what your repair or replacement options are before any work is done. Nothing moves forward without your approval.
Do I need backflow testing if I have a home irrigation system?
Yes. Irrigation systems are among the most common sources of backflow risk and are typically required to undergo an annual test in North Carolina.
How long does a backflow test take?
Most tests are completed in under an hour. If repairs are needed, we will give you an accurate time estimate before starting.
Can you submit the test report to my water authority for me?
Yes. Once your device passes, we handle the documentation and submit your compliance report so you do not have to track that down yourself.
