What it is

The Worcester Bosch pipe PRV, part number 87186819770, is a spare pipe that forms part of the internal pipework inside the appliance. It carries water or gas along the correct route within the boiler, so the pipe run and its connections need to be sound for the appliance to work as designed.

It sits in the manufacturer's pipes and hoses range and is used across the Greenstar Compact family of Worcester Bosch gas boilers, including the 25Si and 27i variants.

Signs this part needs replacing

  • Water weeping or dripping from the pipe or from its joints
  • Boiler pressure dropping repeatedly with no obvious leak elsewhere on the system
  • Visible corrosion, scale or staining along the pipe run
  • Discharge or dripping around the pressure relief pipework
  • A joint that will not seal after being remade

Before you order

  • Confirm the part number 87186819770 or the alternative number 1030799 matches the part being replaced.
  • Inspect the pipe joints for seals or washers that may need renewing at the same time.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
