Operating Instructions
The Cornat Recyklat Siphon functions as an odor trap by maintaining a water seal within its cup. This water barrier prevents sewer gases from entering your living space. Regular use of the sink, which involves water flowing through the siphon, helps to naturally refresh this water seal, contributing to its self-cleaning properties.
Maintenance
To ensure optimal performance and hygiene:
- Regular Self-Cleaning: The siphon is designed for self-cleaning through regular water replacement when the tap is opened.
- Manual Cleaning: For thorough cleaning or to remove blockages, the siphon can be easily unscrewed. Place a bucket underneath before unscrewing to catch any water. Clean the internal components and reassemble, ensuring all seals are correctly seated.
- Leak Checks: Periodically inspect all connections for any signs of leaks. Tighten nuts gently if necessary.
Troubleshooting
Issue: Unpleasant Odors from the Sink
- Cause: The water seal in the siphon may have evaporated or been disturbed.
- Solution: Run water into the sink for a minute to replenish the water seal. If the problem persists, check for proper installation and ensure no leaks are allowing the water seal to drain.
Issue: Leaks at Connections
- Cause: Loose connections or improperly seated seals.
- Solution: Gently tighten all connection nuts. If leaks persist, disassemble the affected connection, inspect the seals for damage or incorrect placement, and reassemble carefully.
Issue: Slow Drainage or Blockage
- Cause: Accumulation of debris (food particles, hair, grease) within the siphon or drain pipes.
- Solution: Manually clean the siphon by unscrewing its components as described in the Maintenance section. If the blockage is further down the drain, professional assistance may be required.
