Additional Details

This 3/4 inch lead free double check valve backflow preventer assembly is designed to prevent the backflow of polluted water from entering into the potable water supply due to backsiphonage and/or backpressure in accordance with national plumbing codes and water authority requirements. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as non-health hazards.

Features

  • Lead Free cast copper silicon alloy body construction.
  • Compact, modular design for easy maintenance with a single top-entry access cover.
  • Two in-line independent positive seating check modules with captured springs and replaceable rubber seat discs.
  • Quarter turn ball valve shutoffs and top-mounted test cocks.
  • ArmorTek coating technology resists electrochemical and microbial-induced corrosion.
  • Equipped with Viega ProPress® adaptors for inlet and outlet connections.
  • Approved for horizontal and vertical "flow up" installations.

A freeze sensor solely provides alerts about a possible freeze event and cannot prevent a freeze event from occurring. User action is required to prevent freeze conditions from causing product and/or property damage. An add-on connection kit (sold separately) is required to activate the freeze sensor.
