What it is

This is Johnson & Starley's complete diverter valve, listed in the Reno Combi Series spare parts manual as the flow manifold assembly. In the boiler it directs hot water from the heat exchanger either to the central heating circuit or to the plate heat exchanger for domestic hot water, depending on demand.

Signs this part needs replacing

  • Hot water and central heating running at the same time, or neither working properly
  • Boiler produces hot water but radiators stay cold (or vice versa)
  • Water leaking from around the valve body
  • Boiler cycling between heating and hot water modes unexpectedly

Before you order

  • Confirm the part number printed on your existing valve matches 1000-0301605
  • Note your boiler's exact model (HE30C, HE37C, HE30CP or HE37CP) and GC number
  • Drain the central heating and domestic hot water circuits before removal, per the manufacturer's instructions
  • Have the work carried out by a Gas Safe registered engineer
