Have you ever been taking a shower and suddenly found yourself standing in a pool of tepid, foul-smelling water? What about having drains suddenly start expelling water back up into the sink? If so, you have a backflow problem. Backflow is a serious issue, especially among homes that use wells or are located in mountainous terrain. It can contaminate your fresh water supply, including your drinking water. For that reason, it’s best to address backflow problems as soon as possible. Read on to find out more about why backflow happens, and how to address it.
Why Backflow Happens
There are two water systems every home: inflow and outflow, or fresh water and waste water. The inflow, or fresh water, is the water you get from the city or from your own wells. The outflow, or waste water, is the water that flows out of your house and into the sewer. These two systems rely on a balance of pressure in order to operate properly. Normally, your inflow system is at a much higher pressure than your outflow. This keeps fresh water flowing into your home, and waste water flowing out of it. However, if a sudden change occurs in that pressure, backflow can occur.
Backflow is essentially what happens when the pressure in your waste water system suddenly becomes stronger than the pressure in your fresh water system. This causes water to flow backwards through the system, which results in waste water coming up into your home.
The best way to prevent backflow is to install a backflow prevention device. Backflow prevention devices are installed in the waste water line, and essentially act as barriers against backflow. If and when backflow does occur, it runs into the valve in the backflow prevention device and is prevented from entering the home.
