Backflow is when the pressure in a typical plumbing system fails and the distribution of water goes to the opposite direction.

Backflow can cause very serious problems to our drinking water. It occurs when there is a reversal of water flow within your pipeline or plumbing systems, potentially causing contaminated water to flow back into the clean water lines and into the main water supply.This is a public health issue and it poses significant health risks by contaminating of clean drinking water.
