How Often Does a Backflow Preventer Need to be Tested?

A backflow preventer is an important piece of equipment that enhances a facility’s plumbing system. Just like any other piece of equipment, it must be well maintained in order to be effective. As a facility manager, knowing how to take care of your backflow preventer will keep it working properly for as long as possible.

How often a backflow preventer needs to be tested depends on its type. There are two main kinds of backflow preventers, and each has its own maintenance requirements. Double check valve assembly (DCV) and reduced pressure zone assembly (RPZ) devices are most commonly used in commercial facilities.

DCV assembly backflow preventers need to be tested at least once every three years. RPZ assembly models, on the other hand, require a bit more maintenance. They must not only be tested annually, but rebuilt every five years. If not, there could be serious harmful backflow.

If you discover anything amiss in the testing of the backflow preventer, it is a good idea to handle it right then. This kind of preventative maintenance will go a long way to minimizing the risk of a major breakdown.
