Alpine NJ – What Is Backflow Testing?

In many businesses and homes in Alpine, New Jersey, the plumbing system is outfitted with a device called a “backflow prevention device,” also known as a Reduced Pressure Zone (RPZ) valve. These are manufactured by companies such as Backflow testers, Watts, and Honeywell.

The RPZ valve serves to prevent sewage backflow into a building’s plumbing, as well as preventing various contaminants from entering the city’s clean water supply. In order to remain in compliance with the city’s regulations, the backflow prevention device needs to be tested periodically by a professional, to ensure that it’s working correctly.

How Backflow Prevention Works

Backflow prevention devices, in the form of RPZ valves, are usually installed in commercial or residential buildings with certain plumbing systems installed: namely, irrigation systems, fire suppression systems, or large boilers. These systems, when in use, have the potential to introduce contaminants into the water supply. For irrigation systems, which are often used for lawns and landscaping, the risk comes from pesticides and fertilizers. Pesticides are toxic if consumed by humans, and fertilizers, in addition to being a health issue, can also cause environmental damage to ponds, bayous, and other bodies of water, through a process known as “eutrophication.” Boilers and fire suppression systems often involve large amounts of water sitting stagnant for periods of time. This can cause minerals and sediments to leech into the water from pipes and water tanks, as well as providing a place for potentially harmful bacteria to grow.

RPZ valves prevent backflow in situations where the water pressure in these types of plumbing systems drops below the pressure in the household plumbing or city water mains. This can happen in the event of a water leak, burst water main, or even the use of a nearby fire hydrant. The difference in pressure causes sewer backflow into the city water supply, which serves as drinking water for the city’s residents.

When this situation happens, the backflow prevention device will open. Instead of allowing contaminated water to get into the water supply, it safely releases it by dumping it out.

Why You Need Backflow Testing

If your home or business has an RPZ installed, you’re required by law to have it periodically tested to ensure that it’s working correctly. The regulations vary by state. In New Jersey, backflow prevention device installation must be according to regulations, and subjected to backflow testing, in accordance with the New Jersey Safe Drinking Water Act. Especially for business owners, backflow testing is crucial to ensure that you’re in compliance with state and local regulations. If your RPZ were to fail in an emergency like a burst water main, or a fire that sets off your fire suppression system, the results could be disastrous. Not having backflow testing can be a major liability, making it important to have it done.
