The presently disclosed technology generally provides a modular support system for plumbing connections. In one example, the system includes a frame, a connector that fits entirely in front of a support stud, and an optional housing. The frame includes symmetrical sides, each including a rail assembly. The connector includes first opposed sidewalls, each having a pair of boxways that receive the rails on any side of a frame unit to form a sliding joint between the frame and connector. Second opposed sidewalls include flexible tabs that engage frame corner flanges to prevent rearward disengagement of the connector from the frame. The housing includes structure for connection with the frame. The housing can be rotated for connection with the frame to receive vertical or horizontal plumbing lines. Connectors can connect the frame units in vertical or horizontal relation, or on either side of a building stud, or to brackets.

A penetration fitting assembly includes a pipe gasket having an annular portion defining a central opening and first and second stem portions extending in opposite directions from the annular portion, an inner ring assembly configured to surround the pipe gasket and including first and second inner ring halves, a ring gasket assembly configured to surround the inner ring assembly and including first and second ring gasket halves, a wall gasket, an outer ring assembly configured to surround the ring gasket assembly and including first and second outer ring halves, and a clamp configured to surround the outer ring assembly. When the penetration fitting assembly is installed, the outer ring assembly compresses the wall gasket against the wall of the sump, the clamp compresses the ring gasket assembly between the inner ring assembly and the outer ring assembly, and the clamp compresses the pipe gasket against the pipe or conduit.

A sealing apparatus for sealing against an opening in a structure for establishing a sealed passage therethrough, comprising a main body having opposed first and second sides, a first hollowed portion projecting from the first side, a second hollowed portion projecting from the second side and a flange between the first and second hollowed portions, the first and second hollowed portions communicating with one another to define a sealed passage for allowing a cable/pipe to pass therethrough.

Disclosed are various embodiments for facilitating the installation of a toilet over a closet collar for a drain pipe. According to various embodiments, a toilet seal assembly is positioned between the toilet and the closet collar, providing a seal between the toilet and the flange of the closet collar. The toilet seal assembly may include a flexible rubber seal and a compressible foam seal ring. The flexible rubber seal may include an annular wall, an upper ring that extends radially inward from the annular wall, and a lower ring that extends radially outward from the annular wall. The compressible foam seal ring may be disposed on the lower ring of the flexible rubber seal.
