Additional Details

This 2 1/2 inch lead free anti-siphon vacuum breaker backflow preventer for hot or cold water prevents the reverse flow of polluted water into the potable water supply due to backsiphonage.

Product Design & Construction

  • Features lead free construction to comply with Lead Free* installation requirements
  • Includes a chemical resistant silicone seat disc, chrome hood, and an atmospheric vent to prevent spilling
  • Equipped with a full-size orifice to assure pipe size capacity and maximum flow
  • The disc has high heat and water hammer shock resistance
  • Lightweight disc assembly prevents spilling under all rates of flow

Operation & Application

  • Designed for hot or cold water applications
  • Ideal for low flow, non-continuous health hazard applications, such as on laboratory equipment
  • Provides high water flow with minimal pressure loss due to streamlined water passages

This device is not to be used under continuous pressure or where there is a possibility that a backpressure condition may develop. For continuous pressure applications, specify Watts Series LF800 pressure type vacuum breakers.
