The Reliance RWC MK3 1-Piece Multibloc is an all-in-one inlet control valve group designed to regulate the incoming mains water supply for unvented hot water cylinders. By combining every necessary safety and control function into a single, cohesive monobloc body, this MK3 design drastically simplifies installation layout, reduces the number of potential leak points, and saves valuable space in tight airing cupboards. The unified brass housing seamlessly integrates a pressure-reducing valve, a high-capacity internal mesh strainer, a check valve for backflow prevention, and an expansion relief valve.
