What it is

The Caleffi Multibloc 28mm 3.5/6 Bar (Circlip Style Prv) is a cold water inlet control valve with an integral circlip style pressure relief valve. It sits within the Popular Cylinder Spares cold water inlet controls range and governs the cold water supply into the cylinder. The assembly uses a 28 mm connection and is set for 3.5/6 bar operation.

Signs this part needs replacing

  • Water weeping or leaking from the valve body or its connections
  • The pressure relief valve discharging or passing water continuously
  • Unstable or fluctuating outlet pressure at the hot and cold taps
  • Visible scale, corrosion or debris around the inlet control

Before you order

  • Confirm the existing valve uses a 28 mm connection
  • Check that the 3.5/6 bar pressure setting matches the installation requirement
  • Verify the valve is the circlip style PRV variant before ordering
  • Confirm the part is being fitted to a Popular Cylinder Spares cold water inlet control assembly
