What it is

The Alpha 1/2 inch drain valve nut is a securing component for the drain valve assembly on the Alpha CB50 gas boiler. It holds the drain valve connection in place on the appliance's water circuit. The part is listed under number 1.6530.

Signs this part needs replacing

  • Water weeping or dripping from the drain valve connection
  • Corrosion, scale or mineral build-up on the nut
  • Rounded or damaged hex flats making the nut difficult to turn
  • The drain valve failing to seal once the nut is tightened

Before you order

  • Check the appliance data badge to confirm the model is an Alpha CB50
  • Confirm the drain valve connection requires a 1/2 inch nut
  • Decide whether the nut alone or the complete drain valve assembly is needed
  • Isolate and drain the boiler before removing the existing nut
