ABSTRACT:
Method and apparatus for providing interruptible fluid flow to consumers is disclosed wherein a consumer distribution system for a fluid, such as natural gas, includes somewhat flexible plastic pipe with that pipe passing through buried access receptacles, such as curb boxes, at strategic locations for easy access to a short section of the supply line at each receptacle location. Each receptacle is adapted to receive a removable shut-off tool having a generally C-shaped frame with a slidable intermediate member for spanning the buried resilient service line within the access enclosure and having a threaded coupling arrangement for collapsing the service line between one end of the C-shaped member and the intermediate slidable member to squeeze the line sufficiently to interrupt fluid flow therethrough. The removable shut-off tool is typically left in the curb box only so long as it is needed there to maintain the blockage of flow with the tool being removed and flow resumed when service suspension is no longer desired.
