Abstract
The fitting with the hose shower comprises a fitting housing at which there is arranged a laterally actuatable control cartridge. Downstream of the control cartridge, viewed with respect to the direction of water flow, there is provided a safety device arranged above the control cartridge. Under normal operating conditions, water flows from the control cartridge via the safety device to an outlet. Under conditions rendering possible a backflow, a backflow preventer of the safety device cuts off the flow path of water and a pipe aerator connects the outflow line or conduit via an aeration path with the environment. As a result, there is precluded a backflow of water into the supply or feed line.
