Washington
Administrative Code (WAC 246-290-490), and Washington
State Department of Health require that all irrigation systems
connected to the
public drinking water supply be equipped with a backflow
prevention
assembly. This device must be tested when installed and annually
thereafter by
a State-certified Backflow Assembly Tester to verify that it is
operating
properly.
Safety
Backflow
is the
reversal of
water flow through pipes due to siphonage or back pressure. A State
Certified
backflow device is required by law and protects your drinking water by
preventing siphonage from your lawn back into your domestic water
supply. If
backflow occurs in your irrigation system, it can cause water
contaminated with
chemicals or even animal wastes to be suctioned backwards into your
drinking
water.
