3. Setup and Installation
Installation of the Cornat odor trap kit is designed to be straightforward due to its standard connections. Ensure all parts are present and undamaged before proceeding.
- Preparation: Turn off the water supply to the washbasin. Remove any existing plumbing components.
- Assemble Drain Valve: Insert the drain valve into the washbasin's drain opening. Secure it from below using the provided gaskets and nuts. Ensure a watertight seal. The valve plug (Ø 38.5 mm) is used to close the drain.
- Connect Siphon Body: Attach the plunger tube to the drain valve. Then, connect the main siphon body to the plunger tube. Use all necessary gaskets and tighten connections by hand, then gently with a wrench if needed, to prevent leaks.
- Install Outlet Pipe: Connect the outlet pipe from the siphon body to the wall drain. Adjust the length and angle as required. Secure with the wall rosette.
- Appliance Connection (Optional): If connecting an appliance like a washing machine, attach its drain hose to the 45° angled hose connection on the siphon. Ensure the connection is secure (connection range: 19-23 mm).
- Leak Test: Turn on the water supply and fill the washbasin. Check all connections for leaks. Tighten any leaking connections carefully.

4. Operating Instructions
The Cornat odor trap operates passively to maintain a water seal, preventing sewer gases from entering your living space. The integrated drain valve allows for controlled water drainage.
- Odor Prevention: The U-bend design of the siphon naturally retains a small amount of water, creating a barrier against unpleasant odors from the wastewater system.
- Drain Valve Function: The included drain valve ensures controlled water flow from the washbasin. To close the drain and retain water in the basin, simply press the valve plug into the drain opening.
- Appliance Drainage: If an appliance is connected, its wastewater will drain through the dedicated connection point into the main wastewater system via the odor trap.
5. Maintenance
Regular maintenance ensures optimal performance and longevity of your odor trap.
- Self-Cleaning: The siphon is designed for self-cleaning through regular water replacement when the tap is used. This helps flush out small debris.
- Manual Cleaning: For more thorough cleaning or in case of blockages, the siphon can be easily unscrewed. Place a bucket underneath to catch any water, then carefully unscrew the bottom section of the siphon. Clean any accumulated debris and reassemble, ensuring all gaskets are correctly seated for a watertight seal.
- Gasket Inspection: Periodically inspect gaskets for wear or damage. Replace if necessary to prevent leaks.
6. Troubleshooting
Address common issues with your odor trap using the following guide:
- Leaks at Connections: If water leaks from connections, gently tighten the nuts. Ensure gaskets are properly seated and not damaged. If leaks persist, disassemble, inspect gaskets, and reassemble.
- Unpleasant Odors: Ensure the siphon always contains water. If the washbasin has not been used for an extended period, run water for a minute to refill the water seal. Check for proper installation and ensure all connections are tight.
- Slow Drainage/Blockage: First, try manual cleaning as described in the Maintenance section. If the blockage persists, it may be further down the drainpipe, requiring professional assistance.
