Plainview Water District Reminds the Plainview-Old Bethpage Community to Have Backflow Prevention Devices Tested

Testing must be facilitated annually by a certified backflow tester

Plainview, New York—With spring quickly approaching and residents getting started on projects in their yards and gardens, the Plainview Water District would like to remind homeowners to have their backflow prevention devices tested. Backflow prevention devices protect the public water supply from external contaminants such as lawn fertilizers. Testing these devices to ensure they are functioning properly before the high-demand irrigation season begins is vitally important to protect our water quality. 

“Annual testing and maintenance of backflow devices when home sprinkler systems come back online plays a huge role in ensuring high-quality water continues to flow to the homes and businesses we serve,” said PWD Commissioner Marc Laykind “Additionally, for your protection, the Plainview Water District encourages customers to inquire if a tester is both licensed and insured.”

Backflow prevention devices keep potentially contaminated water out of the public water supply in the event that pressure drops due to fire emergencies, water-main breaks or other unexpected instances of differential pressure. Testing is particularly important before irrigation systems are turned back on and is often the most economical time to have the test performed.

“The PWD has always stressed the importance of taking preventative measures within your home, as it is impossible to predict an emergency,” said PWD Commissioner Andrew Bader. “We ask that everyone take part in backflow testing as it is best to be prepared for any possible situation that may arise and can cause an adverse effect on our community’s water supply.”

To avoid potential fines, the District encourages residents to arrange for a New York State (NYS) Department of Health certified backflow tester to test your backflow prevention device to make sure it meets all mandated guidelines. The Plainview Water District has a list of New York State certified testers available on the Districts website for those residents who are unsure of who to contact. Any homeowner who has questions about having their device tested is encouraged to contact the District to learn more about the process.

“All residents and businesses throughout the POB community should always do what they can to ensure that our water supply remains safe for future generations and routine backflow device testing is one way to do just that,” said PWD Commissioner Michael Chad. “We ask our community to take part in this simple action that provides a factor of safety to the health and well-being of our community.”
