Method and means for covering the flange of a waste water strainer

In combination with a fluid compartment having a bottom with a waste water strainer mounted in said bottom, said strainer having a cylindrical wall surrounding a vertical cylindrical opening extending through the bottom of said compartment, and a horizontal flange extending outwardly from a level above and adjacent said cylindrical opening and positioned on the bottom of said compartment,

• a waste water insert comprising a cylindrical wall surrounding a vertical cylindrical bore and having an upper end, and a horizontal flange on said upper end extending outwardly from said cylindrical bore,
• the horizontal flange on said insert resting on the horizontal flange of said strainer with a sealant material therebetween,
• the horizontal flange on said insert being a flat planar surface uninterrupted by any vertical projections,
• the cylindrical wall of said insert being of a smaller diameter than the diameter of the cylindrical wall of said strainer to create a continuous space therebetween, and extends downwardly in spaced relation into the cylindrical opening of said strainer,
• the horizontal flange on said strainer having an outer peripheral edge, and a horizontal flange on said insert having an outer peripheral edge with a downwardly extending lip thereon extending over and being in tight engagement with the bottom of said fluid compartment and in engagement with the outer peripheral edge of said horizontal flange of said strainer,
• the cylindrical wall of said insert being free from engagement with the cylindrical wall of said strainer,
• and the sealant between the horizontal flanges of said strainer and said insert providing the sole means of fixed connection between said strainer and said insert.
