What it is

The Worcester 87186804150 is a 28 mm isolation valve supplied complete with a vent, used on Worcester Greenstar FS regular gas boilers. It sits in the boiler pipework and allows the water circuit to be isolated and vented during servicing or component replacement. The valve is a serviceable boiler spare rather than a generic plumbing fitting.

Signs this part needs replacing

  • Weeping or dripping from the valve body or spindle
  • The handle turns but the valve no longer isolates the flow
  • A stiff or seized handle that will not operate fully
  • The vent passing water or failing to seal
  • Water loss when the system is drained down for service

Before you order

  • Confirm your boiler model against the fit list above
  • Check the pipework at the valve position is 28 mm
  • Check whether the vent also needs renewing at the same time
  • Have your boiler's GC number to hand when ordering
