New Millennium's role
in backflow prevention.
Growing public awareness of the necessity to preserve
water quality makes each of us morally and legally responsible to
safeguard our most valuable resource. To help ensure the potable
water supply is protected, New Millennium Fire offers a wide variety
of backflow preventers for both new and existing fire sprinkler
What is backflow?
Backflow is the unwanted reverse flow of polluted water, or other
contaminants, into the distribution system of the potable water
supply. A potential for backflow exists anytime there is a cross-connection
between the potable water supply and any source of contamination
When does backflow occur?
Backflow occurs when conditions exist which will cause backpressure.
Backpressure conditions exist when there is a higher pressure in
the downstream piping than in the supply piping. This condition
allows downstream substances to be pushed, upstream, into the potable
water supply. Backpressures occur when higher pressures downstream
are generated by pumps, thermal expansion, or elevation.
