Although there is no perfect solution to eliminate the theft of the units, and, in fact, those who have taken the
measures outlined below have still experienced the loss of the valves, the following actions are being recommended
by law enforcement, landscapers and plumbers:
Enclose your backflow valve(s) with a protective cage (if you haven’t already).
Secure it with a non-tamperproof lock (a breakaway lock is easily opened and not recommended).
In case of emergency, your maintenance crew should have a copy of the lock’s key.
The cage should be securely mounted to the ground.
Have the cage spot-welded to the bolts to prevent its removal.
Stamp, label or identify the metal with a recognizable code or name of your own.
Post a visible warning sign with something to the effect of: “Theft and damage to this unit will be prosecuted to the fullest extent of the law.”
Camouflage the unit by planting screening landscape a foot or so from the backflow cage. This will make the unit less visible while still allowing for maintenance access if needed. * Inform your onsite building management, security or other staff of the problem and make sure they keep an eye out for thieves. It’s also a good idea to inform tenants so they can contact you should they see something suspicious near these valves.
