The Worcester Bosch connector-overflow pipe is an item of pipework intended for use in the expansion vessel of Greenstar, Greenstar Er P, and Compact boilers. In a boiler, a pipe either allows water into a heating unit, including the mains water supply and the pipework on a wall jig, or is found within an appliance and carries water between the various mechanisms that require it, including the diverter valve and heat exchanger.
