residential plumbingThe backflow prevention device is a type of plumbing product, which is installed on the main water line going into your home or business. The primary purpose of this component is to protect the city’s water supply if a water reversal happens. In simple terms, if the water begins to move backwards, or away from the structure, the device installed will open and dump the water, rather than allowing it to move back into the clean water supply.

Since the purpose of the backflow device is to protect the city water supply, you may wonder why it is necessary to pay for periodic backflow repairs and testing. The main reason is because of cross-contamination, which can occur if waste water moves into the clean water supply line. A professional plumbing service can help avoid this by testing the effectiveness of your backflow device.

How do Backflow Conditions Occur?

There are several ways this condition may occur. In most cases, this occurs if the water pressure in your home exceeds the pressure of the incoming water, or if there is a sudden drop or loss of pressure due to a city water main break. This will cause the potable water to begin swiftly moving in the opposite direction. When this occurs, simple activities such as turning on a water hose and submerging it in a pool will begin back siphoning the water into the main supply. Poor plumbing work can also cause backflow situations.

The Testing Process

There are a number of professional tools used by residential or commercial plumbers to test the effectiveness of your backflow component. The equipment is designed to test the shut off valve, as well as the spring check valves. Once the backflow testing is complete, it is tagged with the company certificated to show it is registered as effective and in good repair.
