Everything Homeowners Need To Know About Backflow Testing

The Importance of Backflow Prevention

Every home has the potential to experience backflow issues. This occurs when pressure changes in the pipes, there’s a break in the main water line, or if a fire hydrant is opened for use. Because water is no longer pushed forward into the home, it will flow backward into the main water line. 

Though homeowners have little control of when this might occur, it’s important to know that this occurrence can and should be prevented.

Backflow Explained

Backflow is a dangerous condition when normal water flow is reversed. Rather than flowing in the intended direction, water flows the opposite way through the pipeline or plumbing. While this may not sound too bad, it’s actually extremely dangerous. Backflow can cause cross-contamination between drinking water and sewage and other hazardous compounds like cleaning fluids. A backflow prevention system is necessary to keep this from happening.

Backflow Prevention Tips

A backflow prevention system does what it says - it prevents backflow. This system is installed on the home’s water pipes and forces water to flow in one direction without returning. It prevents drinking water from contamination due to backflow. 

Preventers are units that function similarly to a gate. They allow city water to flow into the home for use but stop it from flowing backward into the city’s water supply if the pressure drops. When pressure drops and water begins flowing backward, the gate remains shut and the water stays in the pipes instead of flowing back into the city’s water supply. 

Is Backflow Testing Needed?

There are several reasons why a homeowner might need backflow testing. First, if they have an irrigation system for the garden, front yard, or trees, they could be at risk for backflow. Second, if they have a well, they’re also at risk and should be tested. However, even if they don’t have one of these two situations, getting tested is always smart. Why? Because they can be absolutely certain where they stand.

In some places, having a backflow preventer is mandated by law. When purchasing a house that doesn’t have one, it’s a good idea to get tested. If homeowners have had their house for a number of years, testing is beneficial to check and see how the plumbing system is holding up. They’ll only know for certain if they need a backflow preventer installed if it gets tested and a determination is made whether the plumbing requires one.

If one purchases a newer home, it may already have a built-in backflow preventer. In order to be certain that it is working properly, it’s essential to have a certified plumber come to inspect the setup. They’ll install backflow preventers where they are needed and ensure their current preventers are working as they should and are up to date. A preventer that isn’t working is the same as having no preventer at all.
