Viega designs extra-flat and secure floor drains

Viega presents the Advantix Top at the Interclima+élec trade fair in Paris

The Advantix Top floor drain combines high flow rate with maximum safety.

A water seal height of 30 mm even under pressure.

The current demand for floor drains is "flatter, more flow, more safety." This requirement is in line with the trend toward walk-in showers, coupled with ever-lower floors and the need for bathroom renovations.

The Advantix Top floor drain is the practical solution presented by Viega at Interclima 2010. Thanks to the height-adjustable base, the maximum flow rate of 1,0 l/s can be adapted to almost any shower channel or corner drain installation.

Another strong point: Advantix Top guarantees reliable protection against unpleasant odors, despite the water seal height of 30 mm.

In general, floor-level showers require very flat floor drains, since the complete drainage system must be installed below the upper edge of the screed. Until now, this flat construction has always been accompanied by restrictions: the water seal height, for example, was reduced to 30 mm instead of the 50 mm required by DIN EN 1253. In this case, the drain may dry out more quickly. In addition, the drainage flow rate is affected by the missing installation or retention height. This has a direct impact on showering comfort, as the drain is no longer able to cope with the supply flow rate of shower panels, for example.

Thanks to the newly developed Advantix Top floor drain from modular system supplier Viega, such restrictions are now a thing of the past. A height-adjustable base of up to 20 mm and a shortenable immersion tube allow the drain to be determined on-site during installation. The construction height and water seal are always optimal for the installation conditions. This ensures maximum protection against backdrafting and thus against unpleasant odors from the drain.

Viega's developers achieved this goal thanks to the floor drain's special internal structure: In the drain area, the Advantix Top has an additional water seal that acts as a barrier with a through opening and two retention pockets. In the event of underpressure in the drain system, these pockets retain the water seal. As soon as the underpressure is relieved, the water automatically flows back into the drain. This ensures that almost the full amount of water is kept in the drain, regardless of operating conditions.

No odors due to evaporation

A welcome side effect of this operating principle is the improved protection against evaporation of the water seal: the total water volume of almost one liter, due to the design, allows the effective water seal height of the Advantix Top to remain much longer than in conventional siphons. This prevents unpleasant odors from the drain, even when not in use for a long time.

Simple cleaning

Despite this complex construction, handling the new floor drain has remained remarkably simple: to clean, simply remove the existing dip tube. A spiral now allows the connection pipe to be cleaned even beyond the dip tube.



Flat mounting height

To keep the actual installation height of the new floor drain as low as possible, the Advantix Top drain nozzle was positioned at the upper edge of the drain unit. Even with the flattest installation, the height difference to the bare concrete floor is still 20 mm. This makes it possible to lay a connection pipe up to 2 m long without having to raise the drain. Advantix Top thus offers an actual installation height of just 65 mm for many installations.

Despite this low installation height, the flow rate could be doubled. Depending on the height of the floor construction, the flow rate is between 0,8 and 1,0 l/s. This was achieved thanks to lower flow resistances within the siphon and a relatively large basic unit area.
