FLOOR DRAIN Russian patent published in 2019 - IPC E03F5/04 

FIELD: water supply; sewerage.

SUBSTANCE: group of inventions relates to the field of sewage devices. Floor drain comprises a drain body with a connecting element for the drain pipe and connected to the connecting element, extending in the mounting position of the drain body upward an inlet pipe, as well as a waterproof, flexible layer to be applied on the floor surface with a sealing ring, which is intended to be inserted into the inlet pipe of the drain body. Drain body has, measured from its lower side to the upper edge of the inlet pipe, a drain body height which is greater than the height of the floor layer measured from the surface of the floor base, optionally, minus the mounting distance from the drain body to the surface of the base. Inlet pipe consists of material cut with a saw or knife. Method of mounting the floor drain in the floor of sanitary-hygienic premises comprises mounting the drain body on the base surface of the floor, optionally with the formation of a mounting distance between the drain body and the base surface, wherein the drain body is provided with a connecting element for connecting with the drain pipe and an inlet pipe connected to the connecting element, wherein the drain body is oriented and mounted so that the inlet pipe extends upwards. Method also comprises connecting the connecting element of the drain body with the drain pipe, creating a floor comprising at least one layer on the surface of the base, wherein the inlet pipe after creating the floor protrudes upwards beyond the floor surface. Method further comprises cutting off the portion of the inlet pipe protruding above the floor surface, applying a waterproof flexible layer provided with a sealing ring to the floor surface, wherein the sealing ring is inserted from above into the inlet pipe of the drain body, and inserting a nozzle from above into the sealing ring. Nozzle is inserted into the sealing ring so far that the upper edge of the nozzle is at a predetermined distance to the floor surface.

EFFECT: enabling flexible cutting of the inlet pipe of the drain body to its mounting height, which allows matching the height of the drain body with the corresponding structural conditions of the installation.
