Backflow Prevention Program

Backflow, cross-connection and back-siphonage all mean the same thing - used water that has already left your water pipes and is reintroduced into your home's water system.  Backflow is caused by a drop in water pressure (i.e., when fire fighters pull water from a hydrant or while crews are repairing a water main).  A Backflow Preventer is a mechanical device that acts as a check valve to prevent used water from re-entering and potentially contaminating your drinking water.

Why do I need a backflow preventer?

What should I do to protect myself?
