COMPRESSION DRAIN WITH ADJUSTABLE-HEIGHT GRATE |
摘要 |
A compression drain for use with a preformed floor in which the height of the drain grate can be adjusted relative to said floor, and which positively locates the drain housing relative to the subfloor/waste water drain pipe. The arrangement provides a unitary, water tight, assembly that uses very little material to be manufactured, has very few moving parts, and is very easy to install. |

1. A drain for use in connection with a prefabricated shower pan floor, the floor defining a drain aperture, an upper surface and a lower surface, comprising:
a drain body comprising a cylindrical lower section and an annular flange formed as an upper section thereof, at least a portion of an outer surface of the lower section threaded; the lower section of the drain body defining a hollow interior bounded by a cylindrical interior wall, the wall defining:
an annular shoulder;screw threads above the shoulder; anda smooth, waste water pipe receiving surface below the shoulder, such that an upper edge of the waste water pipe may contact a lower surface of the shoulder in abutting relation; a nut having internal threads adapted to engage the screw threads on the exterior surface of the lower section of the drain body so as to compress a lower surface of the flange of the drain body against the upper surface of the pan floor; a drain top support comprising;
a lower cylindrical section defining screw threads on an exterior surface thereof adapted to engage the screw threads defined by the inner wall of the lower section of the drain body;a drain top support flange connected to the lower section of the drain top support; andmeans for attaching the drain top to the support.
