Abstract: A backflow preventing device located downstream of a water control member of a sanitary fitting comprises a casing defining a cavity which communicates with a water feeding pipe and with an air inlet. Two shutting members are serially mounted and displaceable under the effect of a depression in the water feeding pipe, thereby connecting the water feeding pipe with the open air through the cavity. The two shutting members are composed of deformable membranes having different characteristics. One membrane is thin, supple and is umbrella-shaped, the other is thick and has the shape of a disc.

Abstract: A sanitary shower comprises a handle removably securable to the shower body, a head removably securable to the handle, and a flexible conduit for water supply that passes through the shower body and the handle and is secured to the head. The handle is elongated and has a longitudinal slot therethrough, of a width sufficient to receive the flexible conduit when the head is separated from the handle but the handle remains on the shower body. The head has an inlet and two outlets each communicating with a chamber within the head for dispensing water through the two outlets in two directions, and an obturating member in the head comprising a flap that swings about an axis perpendicular to those two directions and in one position closes one outlet and leaves the other outlet open, and in another position leaves the one outlet open and closes the other outlet against the flow of water from the inlet.
