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.

An internal trap drain with large volume/high mass water seal for improved absorption of pressure fluctuations and extended duration of seal against evaporation in low-use conditions. Includes adjustable height strainer and water seal-protected weep holes.

The present invention discloses a filtration device for use in municipal and industrial sewer systems. In one embodiment, the instant invention comprises a device that filters runoff, preventing unwanted chemicals and debris from entering the sewer system. The device comprises a sewer seal that forms a liquid seal to trap hydrocarbons, such as oil, and prevent odors from leaking from the sewer system, while still allowing water to flow through the system. The trap is removable, allowing for easy cleaning, replacement, and maintenance.

A retrofit drainage system for removing excess water from sites having no built-in drainage system. The retrofit drainage system minimizes the risk of pollution in general and specifically avoids environmental spills from disposal equipment, while affording inherent water testing capabilities. The present invention does not use electrical or mechanical engines, but rather utilizes conduits extending between an inlet disposed in a body of excess water and an even lower outlet, therebetween the present invention provides an elevated funnel and funnel valve and shutoff valve for selectively controlling the flow of water from inlet to outlet.
