What it is

The Navien mixing valve adaptor, part number 20047163A, is a connection component used within the LCB 700 Combi boiler range. It forms part of the mixing valve assembly, allowing the valve to be joined to the appliance pipework. It is supplied by Navien for use on LCB 700 Combi models.

Signs this part needs replacing

  • Weeping or visible water at the adaptor joint
  • Corrosion or scale build-up around the adaptor
  • Fluctuating or unstable domestic hot water temperature
  • Difficulty holding a consistent blend at the mixing valve
  • Leaks that return after resealing the connection

Before you order

  • Confirm your appliance is an LCB 700 Combi and check the model against the fitment list above.
  • Check the serial number of your boiler against the listed range.
  • Inspect the mixing valve body and surrounding pipework, as the adaptor may not be the only component requiring attention.
