How to Choose the Right Backflow Preventer Valve

For residential properties, backflow prevention assemblies are most frequently required in conjunction with a lawn irrigation system. Many New Jersey homeowners use extensive sprinkler systems to water their lawns and gardens. In many cases, there’s no inbuilt separation between the irrigation system and the potable water supply– creating the potential for backflow, a situation in which water moves backwards back into your sprinklers. When this occurs, that water can carry fertilizers, pesticides, herbicides, and other contaminants into clean water, a serious health hazard. To prevent this backflow from occurring, you may be required to install a backflow prevention valve (RPZ […]

Common Problems Found During Backflow Testing

Many homes and commercial buildings in New Jersey have a backflow preventer valve installed. These devices are designed to prevent mixing between contaminated water sources and the municipal clean water supply, and are usually installed in areas where those pipes might cross-connect. Backflow preventer valves are commonly used on properties that have large boilers, fire suppression systems, or irrigation systems, which tend to create an elevated risk of backflow. Backflow itself results from pressure differences, causing water to move in the wrong direction and contaminate the potable supply. If you have a backflow valve installed, you’re required to have professional […]

When is a Backflow Preventer Required?

Backflow prevention assemblies are designed to prevent contaminated water from mixing into clean municipal water supplies, which are usually used as drinking water. Contaminants like sediments, bacteria, and fertilizer are a major public health hazard, so in New Jersey, there are regulations in place that require certain buildings to have backflow preventers installed. What is “Backflow”? Simply put, “backflow” means that water flows in the plumbing system have become reversed, causing potable water– clean water you can drink– to mix into the used water, which contains bacteria, chemicals, and other harmful contaminants. Usually, water backflow results from one of two […]
