VAILLANT 010003 DIAPHRAGM SCREW.

Product Information: This part is based around the diverter valve section. The diverter valve is an instrument that only appears in combi boilers. It allows the hot water to be directed to the central heating system (radiators, etc.) or to the DHW system (taps, etc.). This feature is what seperates a normal boiler from a combi boiler due to the fact that a combi boiler wouldn't require a cylinder to provide heating and hot water.

This part is present in 13 different boilers in the Vaillant range including the Vaillant VCW 280 XT , VCW 280 T , VCW 242 E , VCW 240 XT , VCW 240 T .
