What it is

The 6 bar pressure reducing valve cartridge is a serviceable component within the Popular Cylinder Spares cold water inlet controls range. It sits in the cold water inlet control group on an unvented cylinder and regulates incoming mains pressure down to a stable 6 bar at the cylinder inlet. The blue designation identifies it for potable water use.

Signs this part needs replacing

  • Reduced or unstable hot water flow at the taps
  • Water discharging from the expansion relief valve or tundish
  • Inlet pressure drifting above the set 6 bar
  • Banging, humming or vibration from the inlet control group
  • Scale build-up, damage or weeping around the cartridge

Before you order

  • Confirm your cylinder make and model against the fit list
  • Check the existing cartridge is rated at 6 bar
  • Confirm the blue potable water version is the one required
  • Check whether the cartridge alone is needed or the complete valve body
