- Flushing: To flush the toilet, press down firmly on the left-hand trip lever located on the front side of the tank. Hold the lever down briefly until the flush cycle begins.
- Refill: After flushing, the tank will automatically refill with water. The fill valve will shut off once the water reaches the appropriate level.
- Water Conservation: This is a high-efficiency toilet designed to use less water per flush. Avoid holding the handle down unnecessarily after the flush cycle has initiated.
6. Maintenance
Regular cleaning and maintenance will ensure the longevity and optimal performance of your Duravit toilet.
6.1. Cleaning the Exterior:

- Wipe down all exterior surfaces, including the tank, bowl, and base.
- Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
- Avoid using abrasive pads, harsh chemicals, or cleaners containing bleach, as these can damage the ceramic finish.
6.2. Cleaning the Bowl:

- Use a toilet brush to scrub the inside of the bowl, including under the rim.

6.3. Internal Components:
