TECEdrainline – Secondary drainage
Secondary drainage, yes, no or both?
The subject of secondary drainage is being discussed more and more controversially in expert circles. Our view on this has not changed in all these years and is underpinned by many years of practical experience in the field of kitchen and industrial channels.
The only forces at work in the thin tile bed are capillary forces. It is physically impossible for trickles to fall in line with the gradient. Corresponding studies have conclusively demonstrated this.
For hygienic reasons, no matter whether it's in a big kitchen, a swimming hall or in a domestic shower, a drain channel requires an anti-capillary edge that prevents the shower water from penetrating under the tiles.
Optional secondary drainage
Since despite everything there is still a demand for channels with secondary drainage, with the TECEdrainline-Evo TECE now offers an option for secondary drainage without removing the proven anti-capillary edge. The result is the first hygienic secondary drainage on the market.
Trick one: the doubled base
The stainless steel channel (1) is fixed in a hard shell (2). Water (3) would collect in the hard shell beneath the stainless steel channel without backflow.
Trick two: the dual seal
When removing the dip rod (1) the openings (2) in the specially constructed double-lip seal are left clear. If water collected here, it could flow into the drain trap (3).
The anti-capillary edge
The channel body also stays thoroughly closed! Dirt and soap residue can't get under the tiles. TECE thus remains true to itself and the principle of the anti-capillary edge.
