What it is

The Main 5111390 is a water inlet/outlet kit for Main Multipoint FF water heaters. It forms the connection point where the cold water supply enters and the heated water leaves the appliance. The kit is supplied as a service assembly for the Multipoint FF range.

Signs this part needs replacing

  • Water weeping or dripping from the inlet or outlet connection
  • Visible corrosion, scale build-up or pitting on the connection body
  • Reduced flow rate through the appliance at the inlet or outlet
  • Leaks that persist after resealing the pipework joints
  • Physical damage to the connection threads or body

Before you order

  • Confirm your appliance is a Main Multipoint FF or Multipoint FF ErP
  • Check the model and GC number on the appliance data badge against the fitment list
  • Verify the part number 5111390 matches the item you are replacing
  • Inspect the surrounding pipework and seals before fitting, as leaks may originate elsewhere
