Backflow

Flow of water or wastewater in pipes in a reverse direction from that normally intended

Back pressure

Pressure within sanitary drainage system or vent piping system that is greater than atmospheric pressure

>14.7psi

Atmospheric pressure

Back siphonage

Flowing by negative pressure of contaminated or polluted water from a plumbing fixture into a potable water system

Backwater valve

Device installed in piping to prevent the reverse flow of storm or sewage into the drainage system or branches
