Before you buy — quick checklist

  • Confirm your existing switch is rated SPDT — this is not an SPST replacement
  • Verify your system requires a 25-amp rated switch before ordering
  • Check the vacuum actuation pressure range of your current switch matches the V4003P-DX
  • Confirm the mounting footprint and terminal configuration match your existing switch
  • Inspect the vacuum port fitting size on your chemical feed system before installation

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
