STOLEN BACKFLOW VALVES 101. WE NEED YOUR HELP!



Mesa and surrounding jurisdictions have seen an alarming increase in the number of Backflow Valve Thefts hitting the Valley. This crime is costly and inconvenient for our citizens. We need your help to put an end to this trend!


What exactly is a backflow valve?
  • A backflow valve (assembly) prevents water that has become polluted or contaminated by contact with the environment, from reversing direction and flowing backward into a customer's potable water plumbing or in the municipal water distribution system.  Landscape irrigation systems, swimming pool auto fill lines, or plumbing connection equipment and appliances are examples of water applications that can compromise the public water system if appropriate protection is not in place.


How does it affect ME when a backflow valve is stolen?
·         Costs to replace stolen backflow assemblies will invariably be passed on to customers.
  • This includes additional costs relating to property damage to cages, plumbing, pads, and the landscaping associated with a backflow assembly.
  • Disruption of water service to critical care facilities, nursing homes, restaurants, grocery stores, apartment complexes, etc.
  • The integrity of the public water distribution system and public health may be compromised when a backflow assembly is removed and the water system piping is opened to the environment. 

It’s just metal--how much could they really cost to replace?
  • A lot! Prices for a new backflow assembly vary significantly depending on its size and type.  Typical prices may range between $100-$800 dollars just for the assembly.  With labor, fittings, pipe, and repairs to damaged cages and pads, the re installation of a stolen assembly may be between $1000-$3000!


Is there anything I can do to assist with this problem?
·         YES! You are our first line of defense. You are the eyes and ears that will notice the theft! Be on the lookout for suspicious activity in your area. Thieves often target apartment complexes, restaurants, community pools, retention basins, HOAS, churches, hospitals, car dealerships and gas stations.
·         Call 911 immediately if you see suspicious activity occurring near a backflow assembly or metal piping.
  • Record license plate numbers of vehicles where individuals are observed removing a backflow assembly. A location, vehicle make, model and color, and suspect description are very helpful. Do you notice more than one suspect present? Make sure to let the Police know of everything you see.
  • Be advised that backflow assemblies are permanent fixtures.  The only time a backflow assembly may be removed is if another is installed in its place. 
  • Most companies that specialize in backflow service will display their company logo on their vehicle.  Unmarked vehicles associated with activity around a backflow assembly should be suspect.
