Backflow Prevention for HOME

What is a backflow prevention device and why do I need one?

Let’s start with the basics by defining backflow. Water prefers to flow in one direction like, for instance, water sourced from the city that flows into private water supplies, like your home. Backflow occurs when there is a change in the direction of the waterflow causing it to go back into the water supply.


Why backflow is dangerous for you and your family:

This can be dangerous because the backflow can contaminate the water supply with the chemicals found in your yard, like pesticides, or from the dirty water in pools, storm drains and other external water sources. Backflow Prevention ensures your drinking water will stay clean.


What causes backflow:

Water pressure is a term heard quite often. Water flow is, whether fast or slow, determines the amount of pressure behind the flow. If there is a drop in the water pressure in the line feeding your house, say from a water line break, or when a large amount of water is used to fight a fire, then this can create a backflow. Or, your sprinkler system may even create backflow if there is too much back pressure from the pump, if it wasn’t installed properly.

Backflow prevention device inspections

It’s wise to check your town or city’s website to make sure your home irrigation system is in compliance with city, state and federal regulations and codes. Installing a backflow prevention device not only protects your water supply, it also prevents contaminants from polluting the city water system.


It is typically mandated that all backflow prevention devices are installed and tested by a certified backflow tester and tested annually with certified test reports sent to the city’s water protection department.
