Backflow Preventer Theft Protection

Backflow Preventers are being stolen at an unprecedented rate! Thieves take the devices down to the local scrap yard for pennies on the dollar.

The devices are usually ripped out of the ground destroying the underground piping. To prevent your Backflow devices from being stolen, you can do one of the following: pour concrete pads, install cages, or install Sentry theft deterrent systems.

Another great tip is to always paint the devices, painting them cuts the scrap value in half. It is easy to do yourself or if you would like we can take care of it for you!
