Drain unblocking device for baths and sinks - uses water jet from supply tap directed by hose and resilient cup

摘要

The unblocking device is used for cleaning and unblocking of outlets of sanitary equipment such as sinks and baths. The unblocking system is operated by the stream of water from the water supply tap of the bath or sink. This arrangement is relatively cheap and it does not require an external compressed air source. The pressure hose (4) is connected to the water tap (3) by a connector (5). The other end of the hose is connected by a flexible bell shaped cup (6) on the drain (2) to be cleaned. A branch pipe (8) is provided for connection to the overflow (10) and this branch has a stop valve (11).
