What it is
The 4.75 Bar PRV Cartridge Potable (Blue) is a pressure reducing valve cartridge from Popular Cylinder Spares, supplied for use in cold water inlet control assemblies on unvented hot water cylinders. The cartridge regulates incoming mains pressure down to a 4.75 bar set point before the water enters the cylinder. The blue designation identifies the potable water variant.
Signs this part needs replacing
- Outlet pressure at hot and cold taps rising above the 4.75 bar set point
- Pressure fluctuating noticeably when other outlets on the supply are opened
- Water weeping or passing from the valve body or from the relief discharge
- Reduced flow through the inlet control assembly
- Scale or debris visible on the cartridge or in the valve housing
Before you order
- Confirm the existing cartridge is rated at 4.75 bar, as other pressure ratings are not interchangeable
- Confirm the assembly serves a potable water supply, which is what the blue cartridge is intended for
- Check the installation is a Popular Cylinder Spares cold water inlet control unit
- Inspect the valve housing and seals for damage before fitting a replacement cartridge
