ABSTRACT:
A cleaner device for cleaning the valve box or cistern which provides remote access to a valve control body of a valve in an underground pipe line, the device having achieving the cleaning by compressed air passing through a tubular body member, and having an upwardly-open basket for catching the debris stirred up by the moving air. A downwardly-opening socket member at the foot of the device, the socket member being slightly oversize as to the valve's control body, both guides the air stream to give a cleaning impingement of the walls of the valve's control body and provides the mechanical component by which the valve-operating torque is applied to the valve's control body; and at the upper end of the tubular body member a deflector disc baffles moving debris back into the valve box or cistern for causing such debris to be collected in the basket.
