Backflow Prevention - How do I do it?

Things you can do to prevent backflow at your home
  • Have all changes to your plumbing system done by a licensed plumber.
  • Install and maintain hose bib vacuum breakers on all outside faucets.
    • The hose bib vacuum breaker isolates your garden hose from the rest of your plumbing system. Garden hoses are the most likely source of residential backflow. Hoses left in a swimming pool, on the ground in a puddle, or connected to a lawn or garden chemical sprayer without a hose bid vacuum breaker creates a potential for water system contamination.
  • Do not attach any pesticide, chemical, or any other non-potable liquid applicator to your water line.
  • Survey your home to make sure no hoses or pipes are connected to a potential source of contamination.
    • Please contact the DPW (508-966-5813) or Plumbing Inspector (508-966-5821) if you have any questions about the plumbing at your house. We will gladly perform a survey of your plumbing free of charge.
