Safe, clean drinking water is essential for your home or business. To protect the local water supply from contamination, many municipalities require the installation and regular testing of backflow prevention devices. At Coastal Plumbing Services Inc., we provide professional, certified backflow testing throughout Long Island, NY, helping residential and commercial property owners ensure their water systems remain safe and fully compliant with local codes.
CERTIFIED & COMPLIANT
What is Backflow and Why is Testing Required?
Under normal circumstances, water flows in one direction: from the municipal water supply into your home or business. However, a sudden drop in water pressure—such as from a burst water main or heavy demand from a nearby fire hydrant—can cause water to flow backward. This reversal of flow is known as "backflow," and it can pull contaminated water, chemicals, and debris from your property back into the clean public water supply.
To prevent this, backflow prevention devices are installed. Because these devices feature internal seals, springs, and moving parts, they are subject to wear and tear over time.
Regular backflow testing ensures that these critical devices are operating correctly and will successfully stop contaminated water from entering the clean water lines in the event of a pressure change.

Common Questions
Frequently Asked Questions
What causes recurring drain clogs?
In most Long Island municipalities, commercial properties and homes with specific plumbing configurations (like irrigation systems) are required by law to have their backflow prevention devices tested annually.
What happens if my backflow preventer fails the test?
If your device fails, it means it is no longer effectively preventing contaminated water from reversing flow. Our experienced team can typically clean, repair, or replace the internal components of the assembly to restore it to proper working order and ensure it passes certification.
Do you submit the backflow testing paperwork to the water authority?
Yes. After successfully completing your backflow test, our team will handle the necessary documentation and submit the certification paperwork to your local water authority to ensure your property remains fully compliant.
