Abstract
Abstract A well point system including snap-in coupling means between each of the connecting means and the header pipe unit and respective well point assembly. The coupling means includes a sleeve and an insert adapted to be disposed therein, said insert having an outer wall formed with at least one circumferential channel and including a resilient sealing member disposed in said channel for forming a fluid-type seal with said sleeve. The header pipe unit is provided with a sheath snuggly receiving the adjacent ends of adjacent pipe sections, said sheath being pressingly engaged against each of said pipe section by means of bands disposed about the outer peripheral surface thereof. One of said bands is provided with clamp means for releasably securing said band to permit the assembly and disassembly of the header pipe unit. The well point assembly includes spaced inner and outer conduits, the outer conduits being formed with a plurality of axially spaced slits therethrough, each extending partially about the circumference thereof.
