Abstract
A drain has a cup with a fluid outlet to be connected to a conduit, wherein the cup accommodates a water trap. The cup has an axial channel along the circumference, the channel is open upwards and limited by a bottom, a channel wall and a cup wall. The drain further has a circumferential drain wall adapted to fit into the channel, whereby the drain wall is arranged axially movable in the channel, a casting framework arranged releasable around the outer circumference of the drain wall, the framework has a radial extension, and the drain wall has an outward radial flange at an upper end, the radial extension of the flange is equal or less than the radial extension of the framework. A method and a kit of parts for installing such a drain are also disclosed.

A drain comprising a cup with a fluid outlet to be connected to a conduit, wherein the cup accommodates a water trap, the cup further comprises an axial channel along the circumference, the channel is open upwards and limited by a bottom, a channel wall and a cup wall, the drain further comprises:
- a circumferential drain wall adapted to fit into the channel, whereby the drain wall is arranged axially movable in the channel,
- a casting framework arranged releasable around the outer circumference of the drain wall, the framework has a radial extension, and
- the drain wall has an outward radial flange at an upper end, the radial extension of the flange is equal or less than the radial extension of the framework.
A drain comprising a cup with a fluid outlet to be connected to a conduit, wherein the cup accommodates a water trap, the cup further comprises an axial channel along the circumference, the channel is open upwards and limited by a bottom, a channel wall and a cup wall, the drain further comprises:
- a removable circumferential sleeve adapted to fit into the channel, whereby the sleeve is arranged axially movable in the channel and protrudes above the cup and beyond the expected level of the floor wherein the drain is installed,
- a casting framework arranged around the outer circumference of the sleeve, the framework has a radial extension,
- a circumferential drain wall adapted to fit into the channel, whereby the drain wall is arranged axially movable in the channel, and
- the drain wall has an outward radial flange at an upper end, the radial extension of the flange is equal or less than the radial extension of the framework.
A kit of parts for installing a drain in concrete slabs or floors, wherein the drain comprises a cup with a fluid outlet to be connected to a conduit and the cup accommodates a water trap, wherein the cup further comprises an axial channel along the circumference, whereby the channel is open upwards,
- the drain further comprises
- a removable circumferential sleeve fitting into the channel during casting of the floor, whereby the sleeve when installed in the channel protrudes above the cup and beyond the expected level of the concrete floors wherein the drain is to be installed,
- a casting framework arranged around the outer circumference of the sleeve, the framework has a radial extension and is movable axially along the sleeve, and
- a drain wall for replacing the sleeve in the channel once the floor is casted, the drain wall protrudes above the cup and has an outward radial flange at an upper end, the radial extension of the flange is equal or less than the radial extension of the framework on the sleeve.
