In water supply systems in many country houses used vibration submersible pumps “Rucheek”, “Baby” and the like. They are comfortable, compact, require no maintenance, but in winter when turning off the water pump “locks” in their feed and hose, without drain hole, freezes.
The simplest solution is to make the drain hole in the bottom of the hose. However, if it will not be enough, water can make it turn into ice, but if large, it becomes low working pressure.
To solve this problem allows the introduction of hose pump automatic drain valve. It consists of four parts: body and lid with fittings underneath the hose, the rubber gaskets between them and the Cup-shaped valve porsenna.
