What it is

A 3-way diverter valve made by Glow-worm, part number 0020097214 (previously 0020213146). The diverter valve switches the boiler's output between central heating and hot water when a tap is opened; a faulty valve can leave a boiler stuck on heating or unable to produce hot water.

Signs this part needs replacing

  • Boiler produces heating but no hot water, or vice versa
  • Water dribbles from a tap when the heating is running
  • Clicking or humming noise from the valve when switching
  • Boiler gets stuck cycling between heating and hot water modes

Before you order

  • Confirm the part number or GC No. printed on your existing valve
  • Isolate electrical power and water before removing the old valve
  • Fitting should be carried out by a Gas Safe registered engineer
