ABSTRACT:
Pressure reducers (15) for animal watering troughs serve for reducing the water pressure of a water supply pipe which feeds the watering line to a defined, lower watering pressure. In contrast, water of a higher rinsing pressure is required for rinsing the animal watering troughs. For this purpose, the water supply pipe must be directly connected to the watering line via a bypass which bridges the pressure reducer (15).
To avoid the bypass pipe, the pressure reducer (15) is constructed according to the invention in such a way that, by a suitable means, in particular a retaining device (47), the regulating device (46) of the pressure reducer (15) which reduces the water pressure is put out of operation in terms of functioning. The water from the water supply pipe can thus flow at non-reduced pressure through the pressure reducer (15) for rinsing the watering line.
