Residential Home Water Systems have a risk of potential contamination. Connections to irrigation systems, pools, jacuzzis, and hose bibbs are some of the reasons you need a backflow preventer device installed in your home.

Major renovations that modify plumbing or add new water fixtures can alter the way water flows and increase the risk of backflow, prompting the DEP to request the design and installation of a new or upgraded backflow prevention.

Homeowners may receive a notice from the DEP requiring a backflow prevention device if their property is identified as high-risk to ensure the overall safety of the public water system. This can lead to notifications even for properties that haven't had prior backflow incidents.
