What is backflow?
Backflow takes place when water flow reverses due to back siphonage or back pressure.
Back-siphonage may be caused by reduction of supply pressure or when water supply is interrupted. Here are a few examples:
- When a watermain is shut off for repairs
- When internal plumbing is shut off for on-site repairs
- When there is high water demand (i.e., fire fighting, high home water use)
- When there are different elevations (i.e., elevated piping, hilly landscape)
Back-pressure can arises from any water system that operates at a higher pressure than the supply pressure such as booster pumps, high-rise buildings, thermal expansion, or high pressure boilers.
