What Does a Pressure Reducing Valve Cartridge Do?

A pressure-reducing valve (PRV) cartridge helps control the incoming mains water pressure entering the unvented hot water system.

The cartridge is designed to:

• regulate water pressure to 3.5 bar
• help protect cylinder components
• reduce excessive system pressure
• support safe and efficient operation
• maintain balanced water flow within the system

Over time, PRV cartridges can become worn, scaled, or damaged, which may lead to:

• fluctuating water pressure
• valve noise
• discharge pipe dripping
• poor system performance

Replacing the cartridge with a genuine manufacturer-approved part helps restore proper pressure regulation.
