A drain pipe assembly for installation of a basin includes: a drain pipe which is inserted in a drain port formed in a base of basin and has a flange of which an upper end is caught by the drain port; and a fastening member which fixes the basin against the flange, wherein the fastening member polls the drain pipe, which is exposed below the basin, in a downward direction, to upwardly press the basin, thereby fastening the basin and the drain pipe.

A removable trap for lavatory sinks is provided to enable new technologies to be incorporated into just the water trap portion of the sink trap to maximize the performance of the trap in infection control, while at the same time preserving the trap performance features demanded by major building codes. While a traditional P-trap requires the removal of the entire trap for cleaning or replacement, the removable trap presented in this application allows for easy removal of just the U-bend portion of the trap by releasing latch clamps. The U-bend containing the water is the most vulnerable to attack to cleaning chemicals as well as the most effective locus of innovation in materials and methods employed to reduce infectious bacteria forming biofilms within the lavatory trap.

A drain trap for plumbing fixtures that contains integrated access piping that allow a user to easily and efficiently to clean the drain trap. The drain trap includes a U-shaped plumbing trap, a first access pipe, a second access pipe, a first sealing cap, a second sealing cap, and a cleaning brush. The first access pipe and the second access pipe are positioned adjacent to a curved portion pipe of the U-shaped plumbing trap. The first access pipe and the second access pipe each laterally traverse into the curved portion pipe to provide access to the cleaning brush. The first sealing cap is adjacently connected to the first access pipe. Similarly, the second sealing cap is adjacently connected to the second access pipe for a water-tight seal. The first access pipe, the second access pipe, and the U-shaped plumbing trap are in fluid communication with each other.
