What is Backflow? | Bishop Plumbing

Last updated 7 years ago

Often we take the water that comes out of the tap of our homes for granted. You expect it to be clean and safe, but is your water protected from backflow contamination? Backflow is the plumbing term for when contaminated water from various sources falls back into the potable water that comes out of your tap. Fortunately, this is a problem that you or your plumber can fix.

Assess the Situation

First, you need to find out if your home is already protected against backflow. Have your plumber inspect your home to see if it is safe. Professional plumbers will be aware of the issues of the neighborhood’s and city’s plumbing systems. They’ll know exactly what to look for in your home and may even be able to test the water for contaminants for you.

Make a Change

If your home’s plumbing is at risk of backflow, your plumber will be able to make a recommendation on what to do to fix it. Your plumber will probably recommend either establishing an air gap or installing an atmospheric vacuum breaker, also known as an AVB. These may be things an experienced handyman can do, but are often best left to a professional Chicago plumber.

Test Regularly

Once your backflow prevention device is installed, it must be tested every year to ensure that your home is protected from contaminated water. Your professional plumber will check test cocks and shut-off valves to see that the backflow prevention method is working properly.  

To ensure your home is protected against backflow, call us at Bishop Plumbing. We serve the plumbing needs of Chicago, Glenview, Northbrook, Schaumburg, and Arlington Heights. Visit our website or call us at (847) 960-3698 for an appointment today.
