Backflow Prevention 101

Apr 25, 2019

Recently you may have received a letter from us requiring that you install a backflow preventer. 

A backflow preventer is required in a situation where there could be cross contamination between a public water system & well water.  This is called a cross-connection. A cross-connection can result in the backflow of hazardous materials into the water pipes where you live and draw the contaminated water into the system. 

Watch a helpful video from the American Water Works Association:




To prevent cross-connection, a backflow prevention device is installed onto a pipe to only allow water to flow in one direction. Think of it as a one-way gate that allows water to flow into your home’s piping, but stops water if it ever starts to flow back towards the local water supply.

Please visit our cross-connection/backflow prevention page on our website for more information.

Please know, this requirement is to protect our customers. We thank you in advance for your cooperation and assistance. 

If you have any questions or concerns, please contact our Cross Connection Control Department at (407) 260-5065 x 3 or by email at FLbackflow@uiwater.com
