Backflow Prevention Device Owners Beware!

Backflow Preventers are being stolen at epidemic proportions! They take the devices down to the local scrap yard for pennies on the dollar! The devices are usually rippped out of the ground destroying the underground piping! Make sure they have to work for it! Pour concrete pads, install cages and paint the devices. Painting them cuts the scrap value in half. It's easy to do yourself, or have us do it.
