Backflow prevention device new york ny
A very specific and important topic!
In New York City, backflow prevention devices are required by law to prevent contaminated water from entering the potable water supply. Here's what you need to know:
What is a backflow prevention device?
A backflow prevention device is a mechanical device installed in a water system to prevent contaminated water from flowing back into the potable water supply. It ensures that water flows only in one direction, from the potable water supply to the user, and prevents contaminated water from entering the system.
Why are backflow prevention devices required in New York City?
Backflow prevention devices are required in New York City to prevent contamination of the potable water supply. The city's water supply is treated and distributed to ensure it is safe for drinking, cooking, and other uses. However, there are situations where contaminated water can enter the system, such as:
- Cross-connections: When a hose or pipe is connected to both the potable water supply and a non-potable water source, such as a pool or a sprinkler system.
- Backsiphonage: When there is a sudden drop in water pressure, such as during a water main break, and contaminated water is drawn back into the potable water supply.
- Backpressure: When the pressure in a non-potable water system is higher than the pressure in the potable water supply, causing contaminated water to flow back into the potable water supply.
Types of backflow prevention devices required in New York City:
The type of backflow prevention device required depends on the specific situation and the type of water system involved. The following are some common types of devices:
- Reduced Pressure Principle (RPP) device: Required for systems with a high risk of contamination, such as hospitals, laboratories, and food processing facilities.
- Double Check Valve Assembly (DCVA): Required for systems with a moderate risk of contamination, such as residential and commercial buildings.
- Vacuum Breaker: Required for systems with a low risk of contamination, such as residential and commercial buildings with a single-family dwelling.
Installation and maintenance requirements:
Backflow prevention devices must be installed and maintained in accordance with the New York City Department of Environmental Protection (DEP) regulations. The device must be installed by a licensed plumber and inspected by the DEP before it can be used.
Penalties for non-compliance:
Failure to install and maintain a backflow prevention device can result in fines and penalties. The DEP can also shut off the water supply to a property if a backflow prevention device is not installed or is not functioning properly.
Conclusion:
Backflow prevention devices are an essential part of ensuring the safety and integrity of New York City's potable water supply. Property owners and managers must ensure that these devices are installed and maintained in accordance with DEP regulations to prevent contamination of the water supply.
