Basement drains without a backwater valve are ideally suited for basement rooms that lie above the backwater level, are already protected from backwater (for example, by a backwater chamber outside the building) or do not require additional protective measures for other reasons.

We supply our basement drains without a backwater valve with or without an odour trap and/or sludge bucket as well as with a horizontal or vertical outlet.

Odour trap

We offer different drains with an integrated odour trap to protect against unpleasant odours from the sewer system. Many drains can also be equipped with our Multistop waterless odour trap, whose tightly sealing flap provides additional protection against foam and rodents.
