Setup and Installation
The Duravit D1906300 is designed for floor-mounted installation. Professional installation is recommended to ensure proper function and compliance with local plumbing codes.
- Prepare the Area: Ensure the floor flange is properly installed and clear of debris. Turn off the water supply to the toilet area.
- Install Wax Ring: Place the wax ring onto the floor flange or directly onto the toilet's waste outlet.
- Position the Toilet: Carefully lift and lower the one-piece toilet onto the floor flange, aligning the bolts with the holes in the toilet base. Press down firmly to compress the wax ring.
- Secure the Toilet: Install the washers and nuts onto the flange bolts. Tighten them evenly and alternately until the toilet is secure, but do not overtighten, as this can crack the ceramic.
- Connect Water Supply: Connect the water supply line to the toilet's fill valve. Ensure a watertight seal.
- Install Toilet Seat: Attach the plastic toilet seat according to its specific instructions.
- Test for Leaks: Turn on the water supply slowly and allow the tank to fill. Flush the toilet several times and inspect all connections for leaks.

Maintenance and Cleaning
Regular cleaning and maintenance will ensure the longevity and hygienic performance of your toilet.
- Exterior Cleaning: Use a soft cloth and mild, non-abrasive cleaner to wipe down the ceramic surfaces. Avoid harsh chemicals or abrasive scrubbers that can damage the finish.
- Toilet Seat Cleaning: The plastic toilet seat should be cleaned with a mild soap and water solution. Do not use strong chemical cleaners, as they can degrade the plastic.
- Bowl Cleaning: Use a toilet brush and a toilet bowl cleaner designed for ceramic fixtures. Follow the cleaner's instructions.
- Internal Components: Periodically check the fill valve and flush valve for wear. If issues arise, replacement parts are typically available from Duravit or plumbing suppliers.
- Hard Water Stains: For hard water stains, use a cleaner specifically designed to remove mineral deposits, following product instructions carefully.
Troubleshooting
Below are common issues and their potential solutions. For more complex problems, contact a qualified plumber.
- Toilet Leaks:
- Check water supply line connections for tightness.
- Inspect the wax ring for proper seal.
- Examine the tank's internal components (flapper, fill valve) for damage or misalignment.
- Weak Flush:
- Ensure the water level in the tank is at the recommended mark.
- Check for obstructions in the rim jets under the bowl rim.
- Verify the flapper is opening fully and staying open long enough.
