What it is

The Caleffi Multibloc 3.5/8 Bar (Push Fit PRV) is a cold water inlet control valve for Popular Cylinder Spares cylinders. It is part of the Popular Cylinder Spares Cold Water Inlet Controls group. The valve combines pressure reducing and pressure relief functions in a push fit multibloc assembly, rated at 3.5/8 bar.

Signs this part needs replacing

  • Reduced or inconsistent hot water flow at taps
  • Noisy operation or banging from the inlet control during draw-off
  • Visible leaks or weeping from the valve body or push fit connections
  • Fluctuating hot water temperature or cylinder failing to reach set temperature

Before you order

  • Confirm the appliance is a Popular Cylinder Spares model with cold water inlet controls.
  • Check the existing valve is a Caleffi Multibloc rated at 3.5/8 bar.
  • Verify the connection type is push fit.
