Backflow occurs when contaminated water has entered clean water lines by reversing its flow. Backflow is caused by significant changes in water pressure and it occurs at cross-connections between clean and dirty water lines.
Dirty water is likely to contain hazardous materials including, human waste, chemicals, pesticides, and more. This type of contamination can pose significant health concerns. In order to prevent backflow, you can install a backflow prevention device.
This safety backflow prevention device stops backflow and prevents dirty, contaminated water from entering the clean water supply. However, this device needs to be installed correctly and needs to be regularly tested to ensure it is working adequately and keeping hazardous contaminants out of your clean water line.
Backflow testing is a plumbing service that tests your backflow prevention device. This is done by assessing the water pressure level. Backflow can siphon untreated or contaminated water into your clean water supply. Testing your backflow system ensures that your drinking and bathing water is clean and safe for use.

Why Backflow Prevention Matters
Backflow prevention devices help prevent contaminated water from backflowing into the water main. There are two types of backflow: Back-siphonage and back pressure.
Back-siphonage occurs when there is a loss of pressure in the water supply. This loss of pressure allows contaminated water to be sucked into the water main. The most common causes of back-siphonage include a broken water main or firefighters using large amounts of water.
Back Pressure Backflow
Back pressure happens when there is more pressure in the non-potable water lines than in the clean water supply. Back pressure often occurs due to the use of a significant amount of water, such as when using sprinkler systems or power washing equipment.
Why You Need a Backflow Prevention Device
Both types of backflow are dangerous because there is a risk of water supply contamination, which can cause serious illness. In order to avoid this, a backflow prevention device is required at each service connection for properties at risk of backflow.
How Do You Know if You Need a Backflow Prevention Device?
You will be notified by your local municipality when a backflow prevention device needs to be installed. If you have a backflow device, annual testing is required to ensure that the device is working properly.
When you are required to have a backflow prevention device, annual inspections and testing will be required. The testing must be performed by a plumber with proper training and state backflow testing certification. The process only takes about half an hour, but you won’t have water during the testing process.
The backflow testing process includes:
- Recording the condition of the water system and backflow assemblies
- Turning off the downstream shut-off valve and waiting a few minutes
- Shutting off the water supply
- Using specialized test kit hoses and gauges
- Testing the pressure in the system
- Looking for areas where the pressure isn’t right
- Preparing a report with the results of the testing
It is important to understand that backflow testing is a snapshot of a moment in time. The results of the testing show that your system is either in need of repair or working right now. Any needed repairs can be completed at the time of testing. However, passing the testing does not mean the device won’t fail in the future.
