What is a Cross Connection?

“An actual or potential connection between a potable water system and anything that may/ can cause pollution or contamination of the potable water”

SLIDE 4

What is Backflow?

  • A flowing back or reversal of the normal

direction of flow

  • Backflow can happen due to:

back siphonage

  • r

back pressure

slide-5
SLIDE 5

Back Siphonage

When there is negative or sub- atmospheric pressure in the water system

slide-6
SLIDE 6

Back Pressure

When the pressure is greater than the water system supply pressure

nuisance with no chance of being a health hazard

  • M oderate - a minor hazard with a low chance of

becoming a severe hazard
