PRE-TREATMENT:
BACKFLOW PREVENTOR

      * Prevents treated water and disinfectants from backing up into the municipal or building
         drinking water supply.

      * The Backflow Preventor may drip from time to time--THIS IS NORMAL
             - If the Backflow Preventor drips constantly, this may indicate a problem and B.E.S.T.
               should be notified. This does NOT constitute an emergency.
