Should I Worry About Backflow?

Wednesday, November 24th, 2021

You use water in your home or business frequently, whether you run water from a sink, flush a toilet, or take a shower. We usually take the cleanliness of the water for granted, but your plumbing system is designed to keep your water running clearly.

To protect your residential or commercial facilities, a backflow device allows you to receive clean water from your pipes. Guardian Plumbing, a plumbing company located in Annapolis, MD, provides further information about backflow devices and testing services you can get from your local plumber.

What Is Plumbing Backflow?

Water runs through your pipes in designated directions, sending clean water where need and contaminated water away from your property. If clean water reverses its direction, it creates a suction that pulls dirty water into the sanitary water.

Backflow may occur if your plumbing system experiences a large change in pressure, such as if a water main bursts. A tainted water supply could make people sick, so preventing backflow is crucial to a plumbing system.

What Is a Backflow Prevention Device?

To stop backflow from occurring in the event of a plumbing emergency, systems require the installation of a backflow prevention device. This valve can be placed in your plumbing system, usually outside of the building, by an experienced plumber.

The backflow prevention device comes in several types but often features two valves that close automatically if it detects a massive change in water pressure. This stops dirty water from mixing with clean water. Other devices are also able to open and release contaminated water from the affected pipe.

Why Do I Need a Backflow Test?

Most local building codes require that backflow prevention devices be tested by a qualified plumber once a year for commercial facilities. Residential properties may only need testing every three years.

During this test, the plumber evaluates water flow through the device as well as water pressure. They also test the water for signs of contamination, ensuring the device works properly. You should schedule backflow device testing from your local plumber to ensure your system complies with municipal standards.
