Why did I receive this letter?
You have received a letter regarding backflow prevention for one of three reasons:
- your building has been flagged by your local municipality that your plumbing system might have a potential for “backflow,” which means contaminated water could flow backwards into the clean water supply, posing a health risk;
- your building already has a backflow prevention device installed and is due for its annual testing and reporting;
- a cross connection survey of your building and all plumbing connections is to due ensure that no cross-connections exist.
What is a Backflow Preventer?
A backflow preventer is a device installed on a main water line to stop water from reversing direction and contaminating the clean water supply. These devices are commonly found on:
- Irrigation systems
- Fire sprinkler systems
- Main domestic water lines
To function effectively, backflow preventers require regular inspections, annual testing, and ongoing maintenance or repairs as needed.


What is a cross connection?
A cross connection is any actual or potential link between a potable (drinking) water supply and a non-potable source, which could introduce contaminants into the water system.
A cross connection survey is an inspection performed by a licensed professional to identify and assess potential contamination risks in a building’s plumbing system. Depending on the building classification and local municipal regulations, these surveys are typically required every 3 to 5 years.
By properly managing cross connections and ensuring backflow preventers are in good working order, we can safeguard our communities from water contamination.
