What it is

The Worcester Bosch drain cock R1/4 is a small brass-bodied isolation fitting used to drain water from the appliance's hydraulic circuit during servicing or repair. It is supplied by Worcester Bosch and carries part number 87161424310. The fitting is listed under cocks and taps, and sits within the Worcester Greenstar oil and Heatslave External ranges.

Signs this part needs replacing

  • Water weeping or dripping from the drain point when the appliance is running or pressurised
  • Scale, corrosion or green/white deposits around the cock body or spindle
  • The spindle is stiff, seized or will not turn by hand
  • Continued dripping after the drain point has been closed off
  • Damp staining or water marks on the casing or floor beneath the fitting

Before you order

  • Confirm your appliance model and serial number against the compatibility list, as the same drain cock is used across several Greenstar oil and Heatslave External variants
  • Cross-check the alternative number 1018211 and the previous number ZCUNC014 against any documentation you hold
  • Check whether a sealing washer or gasket is required at the same time, as these are separate items
  • Work on the appliance should be carried out by a competent person; this part does not carry gas
