What is Backflow Testing?

Backflow testing is a plumbing service that checks your backflow preventer device by assessing the pressure levels. But what does the backflow preventer device do, and why is it so important?

The backflow preventer does precisely what it sounds like: it prevents the backflow of untreated or contaminated water from being backed up and siphoned into your clean water. That contaminated water might come from a toilet or a hose, bringing the risk of numerous water-borne illnesses. A few examples of water-borne diseases include dysentery, E.Coli and salmonellosis.

When choosing a backflow testing provider, be sure to choose someone who can also provide repair services as needed. That way, if a problem exists, you can fix it immediately before anyone becomes sick. B-N-K Plumbing also provides a full range of other plumbing services.
