HomeBackflow Preventer Installation in Atlanta

A backflow preventer is an essential component of any commercial property’s plumbing. The city of Atlanta requires all commercial water customers to install a backflow prevention device to protect potable water supplies from accidental contamination through plumbing connections. Marquise Commercial Plumbing is here to help you with all your commercial plumbing needs, including septic tank maintenance, hot water heater services, drainage solutions, and leak detection in Atlanta.
Causes of Backflow

Plumbing systems work by transporting water from one location to another in a single direction. A backflow preventer is designed to protect drinking water from contamination through backflow, which occurs when water moves in a direction opposite its intended flow. Backflow can occur in any system where potable and non-potable water lines cross. There are two main causes of backflow:

Backpressure occurs when the pressure inside your plumbing system increases, forcing non-potable water into drinking water lines through plumbing connections. Possible sources of backpressure include pumps, boilers, heat exchangers, or power washing equipment that is connected to your plumbing system.
Backsiphonage is the opposite of backpressure—backsiphonage occurs when there is a drop in pressure inside a plumbing system, which draws non-potable water unintentionally into potable water lines through cross connections. The use of toilets, hoses, and some other plumbing appliances can cause backsiphonage without the installation of a backflow preventer.
