What it is

The RWC CWIC355050 is a 22mm multibloc — a combined control valve assembly used on unvented hot water cylinders to regulate incoming mains pressure and provide over-pressure relief. It is rated at both 1.5 bar and 3 bar, as stated in the product name. The unit is manufactured by RWC.

Before you order

  • Confirm the 22mm connection matches the pipework at the cylinder.
  • Check the 1.5 bar and 3 bar ratings against the cylinder manufacturer's requirements.
  • Review the existing valve arrangement on the cylinder before ordering.
