The Reliance RWC PREL355035 is a specialised, high-quality replacement pressure relief valve (PRV) cartridge designed specifically for the original, legacy generation of the Reliance MK3 1-Piece Multibloc Inlet Control Valve Group. When an unvented cylinder's control manifold begins constantly dripping or venting water through the discharge pipework due to a worn internal seat, this component allows heating engineers to swap out just the faulty relief mechanism rather than replacing the entire expensive brass manifold.
