Prevent Cross Connections

Dangerous cross connections can be prevented by:Leave air gap between your tap and standing water

  • leaving a sufficient gap of at least 2.5 cm between the water supply and a potential contaminated water source
  • never placing the end of a house in contaminated water, such as a dishpan, a wading pool, fish tank or pail
  Do not leave hose in standing water
Ensure sprayers work properly to avoid cross connections
  • attaching a hose connection vacuum breaker to outdoor taps when using a pesticide sprayer with your garden hose
  • installing a backflow prevention valve/device

Vacuum breakers are available from local plubming stores and home improvement centres.
