What it is

The RWC 3/6 Bar Inlet Control Multibloc (2 Piece Old Type) is a combined cold water inlet control assembly for unvented cylinders, manufactured in the two-piece pattern used on earlier cylinder installations. It combines the pressure reducing and inlet control functions that govern the incoming mains supply to the cylinder. This part is listed within the Popular Cylinder cold water inlet controls range.

Signs this part needs replacing

  • Water weeping from the body, joints or connections of the inlet control assembly
  • Outlet pressure drifting above or below the set pressure, giving inconsistent hot water flow at the taps
  • Discharge from the cylinder relief valve despite the system being correctly charged
  • Reduced or erratic flow through the cylinder inlet that cannot be traced to the supply or filter
  • Visible scale build-up or seizure of the adjusting mechanism inside the multibloc

Before you order

  • Confirm the existing inlet control is the two-piece old type pattern, as the newer single-piece version is not interchangeable
  • Check the cylinder's required inlet pressure rating matches the 3/6 bar rating of this unit
  • Verify the cylinder make and model against the fit list above before ordering
  • Inspect the pipework connections and thread sizes on the existing assembly so the new unit matches the installation
