ABSTRACT:
A pipe header assembly for well point pumping apparatus for use with a series of well point risers forced into the ground and extending above ground where they are connected to a pipe header whereby water is pumped out of the ground and conveyed through the pipe header to the pumping apparatus for discharge elsewhere. The assembly includes swing arms connected to the pipe header by an improved slip joint at one end of the swing arms and located between the swing arms and the header and by means of which the swing arms can be inserted in or removed from the pipe header without the necessity of saddles, fittings, threaded joints, or other connections.
A tool, referred to as a jetting adapter is also provided for quick connection to a plain end of the well point risers, which adapter can be simply slipped over a plain end of the riser where it then automatically locks on the riser. The adapter also has a quick sealing joint with the riser and furthermore has a threaded pipe connection with a supply pipe for furnishing pressure fluid to the riser when sinking the latter. The adapter is used for sinking the well point risers into the ground, and it can also be used to pull the riser out of the ground.
