Residential and Commercial Backflow Services

What is a backflow preventer?

Backflow Preventers are mechanical plumbing devices installed in a plumbing system to prevent water from flowing backward in the system. A properly installed, tested and maintained backflow preventer at the service entrance to a building or property can reliably prevent the backflow of water of an unknown quality from flowing back into the community water system.

What is a cross-connection?

A cross-connection is any temporary or permanent connection between a public water system or consumer’s potable (drinking) water system and any source or system containing non-potable water or other substances. An example is the piping between a public water system or consumer’s potable water system and an auxiliary water system, cooling system, or irrigation system.

What can cause backflow?

Backflow can be caused by a sudden drop in the water pressure in a public water main, which can create a sub-atmospheric condition. For example, if a drop in pressure occurs while a hose is in a bucket of dirty water, that water could be sucked back into the public water system, potentially contaminating the water for other users. A drop in pressure could be caused by a variety of things, including a water main break, loss of power at a pump station, etc. Backflow preventers keep this from happening.
