What it is

The Glow-worm 2000802483 is a three-way diverter valve fitted to Glow-worm combi boilers. It directs the heated water produced by the appliance either to the central heating circuit or to the domestic hot water outlets, switching automatically according to demand.

Signs this part needs replacing

  • Hot water at the taps but the central heating stays cold, or vice versa
  • Radiators warm when only hot water is being drawn
  • Reduced or fluctuating hot water flow at the taps
  • Unusual noise from the valve when the boiler switches modes

Before you order

  • Match the part number printed on your existing valve against 2000802483
  • Isolate electrical power and shut off the water supply before removal
  • Fitting should be carried out by a Gas Safe registered engineer
