BackflowIn municipal systems, water is normally maintained at a significant pressure to allow water to flow from the faucet. shower etc. When water pressure fails or is significantly reduced because of something like a burst pipe or frozen pipe, or there is an unexpectedly high demand on the water system, that reduction in pressure in the pipe may allow contaminated water from the ground, from storage tanks or from other sources to be drawn up into the drinking water system.

Backflow prevention devices prevent the backflow, or reversal, of liquids, gases and solids into the water system. The expert plumbers at First Class Plumbing can install backflow prevention devices in new construction, or in existing water systems.
