What it is

The RWC 6 bar pressure relief manifold is a cold water inlet control component used on unvented hot water cylinders. It is supplied under the Popular Cylinder Spares range and forms part of the cylinder's pressure relief and inlet control assembly. This is the old type manifold, which differs from later versions of the same fitting.

Signs this part needs replacing

  • Water discharging continuously from the pressure relief outlet
  • Dripping or weeping from the manifold body or its connections
  • System pressure failing to hold at the correct level
  • Scale build-up or corrosion visible on the manifold
  • The relief valve failing to reseat after lifting

Before you order

  • Confirm whether your cylinder uses the old type manifold or a later version
  • Check your cylinder model against the fitment list above
  • Verify the relief rating required for your cylinder is 6 bar
  • Inspect the existing manifold connections before ordering
