An inline check valve is a mechanism on your backflow prevention device that regulates the flow of water.  In particular this backflow preventer it keeps the water moving in the right direction.  It is designed to be installed in-between joints where you want water to flow through but not backward.

To better understand the function of an inline check valve, one must understand the harmful effects of a phenomenon called backflow.

One of those daily occurrences that we all take for granted is that our water will flow from the city water supply to our home.  The city water system is designed that way and it accomplished that design by the use of water pressure.  When enough pressure is applied at the central water location, the water is “pushed” to the individual homes.  That’s the way it is supposed to work and ninety-nine times out of one-hundred, that’s the way it does work.

It’s that one time it doesn’t work that concerns everyone. If the water pressure suddenly drops then as sure as God made little green apples, the flow of water will reverse, and this reversal in flow is called backflow.  How can this happen, you ask?  The most common culprit is when there is a fire in the city.  Water mains are opened to fight that fire, and the turning-on of those mains means a drop in water pressure at other locations.

So, what happens and why is this something we need to avoid?

Consider the contaminants and pollutants inside your home, from dirty dish and bath water to pesticides on the lawn to chemicals used within the house.  With a reversal of water pressure, all of those contaminants and pollutants would flow back into the city’s potable water supply.

And that would be ugly for everyone!

Enter the inline check valve, designed specifically to shut off any reversal of water flow and stop back flows.

Which means you can sleep well knowing the water system is working exactly the way it was designed to work.
