What can I do to prevent backflow?
  • Keep the ends of your hoses free of any possible contaminants.
  • If your threaded faucets are not equipped with an in-line protection device, install an approved hose bib vacuum breaker or other backflow prevention device.
  • Never submerge hoses in buckets, vats, sinks, tubs or ponds.
  • Use spray attachments or valve spray hoses that have a device to prevent backflow.
  • Do not connect waste drain pipes from water softeners or other treatment systems directly to the sewer system.
  • Ensure all drains are air gapped (unobstructed vertical space between the water outlet and the flood level of a fixture).
