Mini floor drains

Mini drains

Mini drains are used in areas where, for hygiene and aesthetic reasons, stainless steel components are required, and where the small volume of water to be drained allows for the use of a smaller drain diameter.

All ATT floor drains and inspection chambers are manufactured as standard from stainless steel: AISI 304 (EN 1.4301) and AISI 316L (EN 1.4404). The type of drain depends on the load class, the volume of liquid (medium) to be drained, and the structural parameters (e.g. floor thickness).

ADVANTAGES OF DRAINS

• choice of grating depending on the application and load class,
• easy installation,
• thanks to the siphon’s design, each drain also serves as an access point to the drainage system,
• simple design,
• easy to keep clean.

SELECTION OF
DRAINS Drains are selected on the basis of two key parameters:

• the volume of wastewater discharged (selection of the appropriate drain diameter and top section size),
• the size, type and intensity of the load (the load-bearing element is a grating which, depending on its type and height, will support the specified load).

DESCRIPTION OF THE INDIVIDUAL COMPONENTS
OF THE DRAINS

• Bodies – the round shape minimises the accumulation of dirt and ensures it can be easily removed. Welded joints are properly ground to eliminate sharp edges.
  This prevents the risk of injury during installation or cleaning.
• Grates – available in various shapes, sizes and finishes. We select grates based on the load class and the installation location of the drain. We offer the following types of grates: mesh – non-slip, ladder, plate and sheet metal – perforated.
• Sedimentation baskets – their use is recommended where there are large quantities of solid contaminants in the effluent.
• Strainers – used where there are small amounts of solid contaminants.
• Traps – characterised by high functionality and ease of use. They provide easy access to the sewer pipe, quick cleaning and the ability to check the system for leaks.

INSTALLATION OF ONE-PIECE DRAINS

1. The drain connection must be installed at the correct height.
2. Place the drain in the socket of the drainpipe so that the top of the drain is 1–2 mm below the top layer of the floor.
3. Fill the space with concrete.
4. When concreting, ensure that the top of the drain outlet is not narrowed; also ensure that hard-to-reach areas are thoroughly filled with concrete.

FITTING OF TWO-PART DRAIN COVERS

1. We begin the installation by embedding the lower section of the drain into the structural layers of the ceiling. The lower section should be embedded in a recess of 15–20 [mm] to ensure that condensation from the horizontal waterproofing drains properly into the drain.
2. We install the damp-proofing for the ceiling and secure it using the lower section’s clamping ring.
3. The next step is to position and level the upper part of the drain at the specified elevation. The top edge of the drain should be 1–2 [mm] below the floor surface.
4. Once the upper part has been secured, you can proceed to lay the remaining floor layers.
5. Fill the space with concrete.
6. When concreting, ensure that the top opening of the drain is not narrowed; also ensure that hard-to-reach areas are thoroughly filled with concrete.
