Backflows are possible and serious plumbing hazards that can have lethal outcomes to the public if commercial buildings do not fit proper backflow prevention devices. Potable water is usually distributed in one direction from the Municipal water towers to consumers. Yet when water pressure is temporarily lost, a backflow condition can occur that reverses the direction of water to flow from consumer to supplier. A backflow can be harmful, if not deadly, when contaminates are back siphoned into the fresh water supply via a cross connection with a non potable source. In the worst backflow incident recorded, over 1500 persons became ill and 98 people died. Commercial plumbing companies fit backflow preventors on cross connection points to eliminate the very possibility of the backflow threat altogether. Visit Commercial Plumber Birmingham
Usually municipal water is supplied at high pressure to homes and commercial buildings. The turning of taps in homes and offices relieves the water pressure and establishes the one way flow of fresh water. Fire fighting operations or water main breaks can lower water supply pressure below that of the non potable system, and cause back-siphonage of pollutants or contaminates into the potable water system.
The law requires commercial facilities with alternate water sources, fire sprinkles, lab equipment, and boilers to fit backflow prevention devices in the points of cross connection. Property owners who fail to install backflow assemblies where needed are liable for backflow incidents on site. For this reason commercial plumbers install and service backflow preventors on an annually basis to protect the public’s potable water supply. Commercial plumbing service providers protect the public from the grave implications of having non potable substances reach the potable water supply.
