If you received a letter from Missouri American Water requiring you to install a Reduced Pressure Backflow Device, you may want to know that they didn't really perform any ''cross-connection control inspections'' to determine this. They just ASSUMED that everyone has in-ground sprinkler systems in our subdivision (if you do have an in-ground system, you are required to install this device). If you don't have a sprinkler system, CALL them and they will come out to verify you don't have one and then remove your name from the list!
