ABSTRACT:
A device for unclogging blocked pipes, tubes, drains and other conduits employing a source of compressed gas such as a CO.sub.2 cartridge or air compressor and a secondary source of compressed gas and/or liquid. A compressed gas storage chamber receives and holds the compressed gas until a desired predetermined pressure is reached at which time a valve is opened allowing the gas under pressure to flow to the conduit to be unclogged. Simultaneously, and if required, a secondary source of compressed gas and/or liquid can be led into the conduit to be unclogged, downstream of the storage chamber release valve. An automatic safety gas relief valve is also disposed downstream of the storage chamber release valve for safety.
