What it is

This is a UCP-brand motor-driven 3-way diverter valve, cross-referenced to Ariston part number 997147 (GC E25-427). It switches the flow of heated water between the central heating circuit and the domestic hot water circuit, so the boiler can supply either taps or radiators on demand.

Signs this part needs replacing

  • Boiler stays on central heating and won't produce hot water at the tap, or vice versa
  • Water temperature fluctuates when switching between heating and hot water demand
  • A humming or buzzing motor with no valve movement
  • Water leaking from the valve body or motor housing

Before you order

  • Confirm the GC number and part number on your boiler's data plate match this listing
  • Isolate electrical power and the water supply before removing the old valve
  • Have a Gas Safe registered engineer carry out the replacement
