What is Backflow and Why is it Important to Prevent?
Backflow is a term in plumbing for an unwanted flow of water in the reverse direction which can cause contamination of potable water supplies with foul water. Backflow can occur for one of two reasons, back pressure or back siphonage.
Prevention where possible is extremely important! Once Backflow occurs the contaminated or stagnant water could not only flow backwards into your drinking water but can flow into the water mains of homes, businesses, and schools. This in turn could cause sickness or in some cases even death.
How to Prevent Backflow and Maintain a Safe System
Plumbing code and state law requires the installation of an approved backflow preventer on all point of use water lines where necessary. These backflow devices could be non-testable or testable devices.
Non-Testable Backflow Devices
For example your outside hose bib is required to have vacuum breaker installed. This is a non testable device but it should be inspected by your local plumber, for proper operation, yearly.
Testable Backflow Devices
Required for all residential and commercial fire suppression/sprinkler
systems, Lawn Irrigation Systems, Pier Lines, and other Outside Water
Piping. Once installed these backflow prevention devices require a
certification test, then additional certification tests are to be completed
annually or following any repairs by a MD State Certified Backflow
Tester
