WHY IS ANNUAL BACKFLOW TESTING REQUIRED
Understanding New York State Backflow Prevention Requirements
New York State law mandates annual testing of all backflow prevention devices installed to protect the public water supply.
​
Legal Authority:
• New York State 10 NYCRR Section 5-1.31
• Westchester County Health Department regulations
• Local municipal water authority requirements
• EPA Safe Drinking Water Act compliance
​
Who Must Comply:
• All residential properties with backflow devices
• All commercial properties with backflow devices
• Multi-family residential buildings
• Industrial facilities
• Any property with cross-connection potential
​
Testing Frequency:
• Minimum: Once every 12 months
• Some devices: More frequent (as required by authority)
• After any repair or parts replacement
• Following any building modifications affecting device
WHY BACKFLOW TESTING LAW EXISTS
Protecting Public Health
​
Backflow prevention devices are the last line of defense protecting our drinking water from contamination. Without proper testing, these devices can fail without visible symptoms, creating serious health risks.
​
Real Contamination Risks:
From Residential Properties:
• Fertilizers and pesticides (irrigation systems)
• Pool chemicals (chlorine, algaecides, pH adjusters)
• Boiler treatment chemicals
• Antifreeze from radiant heating systems
• Water softener chemicals
• Bacteria from stagnant water
​
From Commercial Properties:
• Industrial chemicals
• Food processing contaminants
• Medical facility waste
• Car wash chemicals
• Cooling tower bacteria (Legionella)
• Firefighting foam chemicals
• Laboratory chemicals
​
The Danger of Backflow:
​
Backflow occurs when contaminated water flows backward into the clean water supply due to:
• Back pressure (downstream pressure exceeds supply pressure)
• Back siphonage (negative pressure in supply line)
• Water main breaks
• Fire hydrant use
• Pump failures
• Supply line repairs
​
Without a functioning backflow device, contaminated water can:
• Enter your home's drinking water
• Contaminate the neighborhood water supply
• Spread to the entire municipal system
• Cause serious illness or death
• Result in expensive water system cleanups
BEST PRACTICES FOR COMPLIANCE
Staying Ahead of Requirements
​
Recommended Schedule:
​
30-60 Days Before Due Date:
• Schedule annual test
• Allows time for repairs if needed
• Avoids last-minute rush
• Prevents violations
​
Keep Records:
• Save all test reports (7 years recommended)
• Document submission confirmations
• Track due dates
• Maintain device service history
​
Use Reminder Service:
• Sign up for automatic reminders
• J&J Backflow provides FREE reminders
• Email and text notifications
• Never miss your deadline
​
Plan for Repairs:
• Budget $100-$500 annually
• Most devices: testing only
• Some devices: minor repairs
• Older devices: plan for replacement
​
Property Managers:
• Maintain device inventory
• Track multiple due dates
• Coordinate access
• Budget appropriately
• Use professional tracking systems
Backflow Testing Legal Requirements FAQs
Q: Can I skip testing if my device looks fine?
A: No. Visual inspection cannot determine if a device is functioning properly. Most failures are internal and invisible. NYS law requires annual testing regardless of appearance.
​
Q: What if I haven't tested in several years?
A: Get tested immediately to minimize penalties. Contact us—we can often schedule same-day or next-day service to resolve violations quickly.
​
Q: Does testing guarantee my device won't fail?
A: Testing verifies current functionality. Devices should still be monitored between tests. Report any leaks or pressure changes immediately.
​
Q: Can I delay testing a few months past due?
A: No. Testing deadlines are legal requirements. Violations begin immediately after due date. Water authorities actively enforce with fines and service disconnection.
​
Q: What if I didn't know testing was required?
A: Ignorance of the law doesn't excuse non-compliance. Water authorities will still issue violations. Get tested immediately if overdue.
Q: How do I find out when my test is due?
A: Check your last test report, contact your water company, or call us at 914-403-0181. We can help determine your due date.
​
Q: Can testing requirements change?
A: Yes. Water authorities can change testing frequency or requirements. Always follow current requirements from your water purveyor.
