What is backflow?

Backflow refers to wastewater that made its way back into your potable water supply. Usually caused by an unexpected change in water pressure, the flow of used, nonpotable water reverses and creates what is referred to as a cross connection (where potable and nonpotable water meet). Backflow is usually contaminated with waste, bacteria, chemical residue and various other pollutants.

These materials can pose a significant risk to your well-being and safety, which is why backflow testing and prevention devices are so important. Whether you’re protecting your loved ones or the public, professional backflow tests from Expert plumbers help in keeping you safe.
