What it is
The 4.5 Bar PRV Cartridge Potable (Blue) is a pressure reducing valve cartridge supplied by Popular Cylinder for their cylinder cold water inlet controls. It regulates the incoming mains pressure down to a 4.5 bar set point before the water enters the cylinder. The blue identification denotes the potable water variant.
Signs this part needs replacing
- Inlet pressure downstream of the valve reads consistently above or below the 4.5 bar set point
- Water pressure at the outlets fluctuates noticeably when other taps or appliances are used
- The valve passes water through with no reduction, or restricts flow excessively
- Dripping or weeping from the cold water inlet control assembly around the cartridge
- Scale or debris build-up on the cartridge affecting its regulation
Before you order
- Confirm the cold water inlet control assembly on your cylinder matches the Popular Cylinder Spares range
- Check the existing cartridge is the 4.5 bar potable (blue) version before ordering
- Verify the pressure setting required for your installation against the cylinder manufacturer's instructions
- Isolate the mains supply and depressurise the cylinder before fitting
