A vacuum breaker is a small but important part of a standard garden hose. It attaches the faucet or hose bibb to the hose and is purposely made to be difficult to remove since it prevents water from flowing backward. Water back-flow is a very dangerous situation, as it can possibly contaminate the entire water supply. With proper installation and use, vacuum breakers can work properly for several years without replacement. However, vacuum breakers should be checked regularly for leaks and other possible damage to make sure they are working properly. If you need to replace a vacuum breaker, you have to remove it.

Things You'll Need

  • Pliers
  • Screwdriver
  • Lubricant (optional)
