Have you ever been taking a shower, or washing your hands, and noticed gross water bubbling up out of your drains? That’s called backflow, and it’s a serious problem for your plumbing system. In addition to being a very damaging issue, backflow is also quite common. So common, in fact, that the majority of municipalities in the country have made it a requirement for homes to be equipped with a backflow prevention device. Let’s take a look at why backflow prevention devices are a good idea, and why you should have one installed if you don’t already have one.
What Is Backflow?
Backflow is the result of a sudden pressure imbalance in your plumbing system. Normally, the plumbing system flows in a single direction, through the home and into the sewer system. However, if that balance of pressure between the sewer and the plumbing system is interrupted, sewer water can be sucked back up into the home. This contaminates plumbing pipes designed to only handle fresh water, making them a biohazard until they can be flushed out. That takes a lot of time, money, and effort, which is why it’s much easier to install a backflow prevention device in the home.
Backflow Prevention Devices
There are many backflow prevention devices available on the market, but the most common of these is a one-way valve installed in the sewer line. When everything is flowing as it should, the valve remains open. If backflow ever occurs, however, the valve snaps shut and prevents sewer water from entering the home. As long as you’re careful to have your backflow prevention device checked at least once a year, the system should protect quite well against backflow.
