What it is

The RWC 315I is an adjustable pressure reducing valve with a 1.5–6 bar setting range and a 3/4 MBSP male threaded connection. It is used on Popular Cylinder cold water inlet controls to regulate the pressure of the incoming cold water supply to the cylinder. The valve is part of the cold water inlet control assembly on the cylinder.

Signs this part needs replacing

  • Downstream pressure higher or lower than the set value, with no response to adjustment
  • Discharge from a pressure relief or expansion relief valve on the cylinder
  • Pressure fluctuating noticeably at hot or cold outlets when taps are opened
  • Water hammer or knocking noise originating at the valve
  • Reduced or restricted flow through the valve

Before you order

  • Confirm the connection thread and size, 3/4 MBSP, matches the existing valve
  • Check the required outlet pressure setting range suits the cylinder installation
  • Verify the valve is listed for Popular Cylinder cold water inlet controls
  • Confirm the existing valve is an RWC 315I before ordering
