Emory Plumbing will install all types of these devices including optional safety cages. We are also experienced and trained to repair and certify your backflow device in accordance with the water district regulation.

How Serious is Backflow?

The term backflow refers to any unwanted flow of non-potable or used water or substance from any domestic, industrial or institutional piping system into the potable, or pure, water distribution system. The direction of flow under these conditions is the reverse direction from that intended by the system, and normally assumed by the owner of the system.

Any change of system pressure wherein the pressure at the supply point becomes lower than the pressure at the point of use can cause a reversal of flow in the distribution main, or in the customer’s system. In an unprotected situation, the water at the point of use will then be siphoned back into the system, potentially polluting or contaminating the remainder of the system. It is also possible that the contaminated water could continue to backflow into the public distribution system.

Cross-connection

Cross-connection refers to the point at which it is possible for a non-potable substance to come into contact with the potable drinking water system. In order to prevent backflow from happening at the point of cross connection a backflow prevention assembly needs to be installed. It is important, however, that the backflow prevention assembly match the particular hydraulic conditions at that location and is suitable to protect against the degree of hazard present.
