What it is

The RWC 8 bar pressure relief manifold is an old-type cold water inlet control component manufactured by Popular Cylinder Spares. It forms part of the cold water inlet control group on unvented cylinders, providing the 8 bar pressure relief function that protects the cylinder from over-pressure. It is supplied as a manifold assembly for the older inlet control arrangement.

Signs this part needs replacing

  • Water discharging from the pressure relief outlet when the cylinder is not overheating
  • Continuous dripping from the tundish with no expansion or heating demand
  • The relief valve failing to reseat after operating
  • Scale or debris preventing the valve from sealing correctly
  • Visible damage, corrosion or weeping at the manifold body or connections

Before you order

  • Confirm your cylinder model against the fitment list above
  • Check whether your cylinder uses the old-type inlet control arrangement, as this manifold is the old type
  • Inspect the existing manifold for the 8 bar rating and connection layout before removal
  • Verify the fault lies with the manifold rather than the expansion arrangement or cylinder thermostat
