Cross-Connection and Backflow

We all want our plumbing systems inside to stay functional and provide us with the cleanest water. Sometimes we run into issues such as water leaks, clogged toilets, blocked drains, or polluted water. All of these can all cause problems and will negatively affect how we use our home. One of the most common plumbing issues that may occur is having a cross-connection and backflow. A cross-connection is a connection between a potable drinking water pipe and a non-potable source. When there is a cross-connection, there is a higher chance of having a backflow.

Backflow is the unwanted flow of non-potable substances back into the consumer’s plumbing system and/or public water system (i.e., drinking water). 

Preventing backflow

Of course, you want to prevent backflow from happening. So, how can you possibly do it? Here are some ways you should take note:

  • Keep all the hoses and faucets away from possible contaminants to lessen the risk of experiencing contamination.
  • Do not submerge hoses in buckets and even in pools and tubs. 
  • When there is a change in water pressure, make sure to make an air gap. An air gap will prevent the hose from sucking the liquid backward.
  • Installation of backflow preventers and devices.

Backflow preventers are mechanical devices designed to prevent backflow through cross-connections. However, for backflow preventers to protect as designed, they must meet stringent installation requirements.

Cross-connection and backflow
Backflow is an unfortunate plumbing problem that can endanger your family’s health and create a potential problem that may affect your quality of life. Make sure that your home’s plumbing systems are fully functional with no underlying problems that can happen. Consider installing backflow preventers and devices today to protect your water quality and ensure your safety all the time.
