METHOD FOR WATER REMOVAL FROM SUPPLY PIPE OF WATER COLUMN Russian patent published in 2010 - IPC E03B9/20 

FIELD: construction.

SUBSTANCE: invention refers to the field of sanitaryware devices. Method for removal of water from supply pipe of water column consists in placement of dynamic element in inner volume, formation of required throughput hole for water supply along pipe by means of dynamic element change. As outpouring flow is disconnected, residual water is removed from pipe. At the same time dynamic element is placed in inner volume of pipe, required throughput section for water supply is formed by change of diametre or volume of dynamic element, and residual water from pipe is removed along direction of its feed, reducing throughput section by means of supply of non-freezing liquid or gas into inner space. Liquid or gas are supplied as flow is disconnected via rigid tube, and filling is started from the side, which is opposite to drainage.

EFFECT: improved operation of device during light frosts.
