Abstract: A valve arrangement comprises first and second valves mechanically interconnected for synchronous operation with one another so as to be switchable by a single action between first and second fluid flow configurations. The first configuration provides a first path for first fluid to flow from a first inlet to a first outlet and a second path for second fluid to flow from a second inlet to a second outlet. The second configuration provides paths for first fluid to flow from the first inlet to both the first and second outlets while closing the path from the second inlet. In one application, the arrangement allows a convenient method of disinfecting a water-consuming appliance such as a shower.

Abstract: A special mounting apparatus is provided to support and locate a piece of equipment, especially a shower mixing valve in a wall cavity between a base wall and an outer facing, the mounting apparatus comprising a support member for securing to the base wall, a carrying plate serving to carry a piece of equipment e.g. fluid valve, and a jacking device for positioning the carrying plate relative to the base wall the device including a plurality of threaded studs attached to the support member and corresponding sleeve-form positioning nuts coupled to the carrying plate and threaded to the studs so as to form a telescopic assemblage therewith, compression springs being present between the nuts and the carrying plate. The mounting apparatus permits by selective adjustment of the nuts selective spacing of the carrying plate from the support member and also comprehensive tilting of the carrying plate relative to the support member to cater for angular irregularities at the base wall.
