What it is

The 5 Bar PRV For Multibloc (New Style) is a pressure reducing valve supplied under the Popular Cylinder brand for use with Multibloc cold water inlet control assemblies. It forms part of the cold water inlet control group on an unvented cylinder installation, where it governs the incoming mains pressure to the cylinder. This is the new style version of the valve.

Signs this part needs replacing

  • Discharge or weeping from the valve body or its drain outlet
  • Outlet pressure at the cylinder rising above the set 5 bar
  • Noticeably reduced flow rate through the cold water inlet controls
  • Pressure at hot and cold outlets varying or pulsing during use
  • Scale or debris build-up around the valve affecting its operation

Before you order

  • Confirm the installation uses a new style Multibloc cold water inlet control assembly
  • Check that a 5 bar setting suits the cylinder and the incoming mains supply
  • Verify the valve position and connection arrangement on the existing inlet control group
  • Note the part reference HRP0440 when comparing against the fitted component
