Backflow is the unwanted reversal of liquid flow from supply lines into the potable water system. This entails a health risk for people as these sources are likely to be polluted. Once the fluid flows back into the pipes, it may carry chemicals, debris and other contaminants that will affect the drinking water, which makes it unsafe to consume. The situations that usually cause this process to occur are the following:
Back Siphonage – the supply pressure is greatly reduced due to cases such as leaking or sudden use of an excessive volume of water.
Back Pressure – the pressure is higher than the main due to some means like recirculation pumps.
These two are likely to transpire when the water main connects to a plumbing fixture or a possibly contaminated system. This is known as cross connection. Since plumbing is one of the most essential utilities in houses, it is crucial to be properly installed and maintained.
