Plumbing sealing system, comprising: (a) a fixture including a flange adapted to lie with an edge in spaced relationship to a vertical wall surface adjacent an aperture in the wall, and (b) a sealing element in the shape of an annulus of circular cross-section lying along and firmly attached to the said edge, while extending into the space between the plane of the edge and the wall surface, the sealing element being formed of an elastomer that is resilient and impervious to water, wherein the said edge of the flange defines a closed circular path confined to a single plane circumscribing the aperture in the wall, and wherein the sealing element has a porous, very resilient inner body completely surrounded by a non-porous, moderately-resilient skin, wherein the edge of the flange has a groove with a depth at least equal to the radius of the sealing element, and wherein the sealing element fits snugly in the groove.
