Backflow contamination is where the normal flow
of our safe drinking water supply is reversed, allowing contaminated
water to enter our drinking water supply.
Surprisingly, there are numerous situations present
in our own homes that cause backflow contamination. These situations
are an ever-present threat to our family's health and welfare.
Ironically, the ordinary garden hose is the most common offender
as it can be easily connected to the mains water supply and
used for a variety of potentially dangerous applications.
Backpressure backflow is the reversal of normal flow in a
system due to an increase in the downstream pressure with
in the system of the property, above that of the supply pressure.
A cross connection is simply a direct arrangement of a piping
line which allows the mains water supply to be connected to
a line which contains a contaminant.
