Have you ever had tepid, foul-smelling water flow back up out of your drains? If so, you’ve got a pretty big problem. That behavior is called backflow, and it can pose a serious biohazard if it’s not taken care of immediately. Backflow is an extremely common occurrence, but far too many people still don’t know what it is or how to stop it. If you’ve ever experienced backflow, or aren’t sure whether or not you have a backflow prevention device installed, read on for more information.
What is Backflow?
Backflow is essentially when sewer water flows backwards up into your home. Normally, there is a balance of pressure between your plumbing system and your sewer system. This pressure balance allows water to flow from your plumbing system down into your sewer system, as it should be. Backflow occurs when this pressure balance is disrupted. This can happen when either the pressure in the plumbing system suddenly decreases, or the pressure in the sewer system increases. Either way, sewer water ends up flowing up through pipes that are only supposed to handle fresh water. This contaminates the pipes, making them unsafe to use until they’ve been properly flushed out. This is why backflow prevention is so important.
The best way to deal with backflow is by preventing it entirely. There are a number of backflow prevention devices on the market, but the most popular is a simple one-way valve that is installed in the sewer line. When the system is operating normally, the valve stays open and allows water to flow through it. When backflow occurs, the valve snaps shut and prevents sewer water from contaminating the plumbing network.
