What it is

The Altecnic 1 F Double Check Valve is a backflow prevention component with a DZR (dezincification-resistant) body. It sits within the Altecnic check valve range and is listed for boiler applications. Its function is to allow flow in one direction only and stop reverse flow through the pipework.

Signs this part needs replacing

  • Water passing back through the valve when flow should be one-way
  • Persistent drip or weep from the valve body or its connections
  • Visible corrosion, scale or dezincification on the body
  • Loss of system pressure or repeated air ingress linked to backflow
  • Valve no longer seating correctly, allowing cross-connection between circuits

Before you order

  • Confirm the connection size and thread form match the existing pipework
  • Check the flow direction arrow aligns with the intended installation
  • Verify the valve suits the Altecnic check valve range and the appliance it serves
