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 systems.

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 or pollution.

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.
