4. Setup and Installation
Installation of the Duravit Starck 3 Floorstanding Toilet Bowl requires careful attention to plumbing connections and proper sealing. It is highly recommended that installation be performed by a licensed plumber.
4.1. Pre-Installation Checks
- Ensure the floor is level and structurally sound to support the toilet bowl and user weight.
- Verify that the rough-in dimensions in your bathroom match the specifications of the toilet bowl. Refer to the technical diagrams below.
- Turn off the main water supply to the bathroom.
- Clear the installation area of any debris or old fixtures.
4.2. Installation Steps (General Guidelines)
- Prepare the Flange: Ensure the floor flange is securely mounted to the floor and free of obstructions.
- Install Wax Ring: Place a new wax ring (not included) onto the floor flange or directly onto the toilet bowl's waste outlet.
- Position the Bowl: Carefully lower the toilet bowl onto the floor flange, aligning the bolts with the holes in the base of the toilet. Press down firmly to create a seal with the wax ring.
- Secure the Bowl: Install washers and nuts onto the flange bolts. Tighten them alternately and evenly until the toilet is secure, but do not overtighten, as this can crack the ceramic.
- Connect Water Supply: Connect the flushometer (if applicable and purchased separately) to the water supply line and the toilet bowl's inlet. Ensure all connections are watertight.
- Install Toilet Seat: Attach the toilet seat (if purchased separately) according to its specific instructions.
- Test: Turn on the main water supply and check for leaks. Flush the toilet several times to ensure proper operation.

5. Operating Instructions
The Duravit Starck 3 Floorstanding Toilet Bowl operates using a gravity flush system, typically activated by an external flushometer (not included). To operate:
- Ensure the water supply is turned on.
- Activate the flushometer handle or button. This will release a measured amount of water into the bowl, initiating the flush cycle.
- The bowl will then refill to its normal water level.
Note: The performance of the flush system is dependent on the type and quality of the flushometer installed.
6. Maintenance
Regular cleaning and maintenance will ensure the longevity and hygienic performance of your Duravit Starck 3 toilet bowl.
6.1. Cleaning the Ceramic Surface
- Use a soft cloth or sponge with mild, non-abrasive bathroom cleaners.
- Avoid abrasive powders, scouring pads, or cleaners containing harsh acids, alkalis, or bleach, as these can damage the ceramic glaze.
- Rinse thoroughly with clean water after cleaning and wipe dry to prevent water spots.
6.2. General Care
- Periodically check all connections for leaks and tighten if necessary.
- Ensure the toilet seat (if installed) is properly secured and cleaned regularly.
7. Troubleshooting
This section addresses common issues you might encounter with your toilet bowl. For more complex problems, consult a qualified plumber.
| Problem | Possible Cause | Solution |
|---|---|---|
| Weak Flush | Low water pressure; partially closed water supply valve; issue with flushometer. | Ensure water supply valve is fully open. Check flushometer for obstructions or malfunction (refer to flushometer manual). |
| Leaking at Base | Loose flange bolts; damaged wax ring; cracked ceramic. | Gently tighten flange bolts. If leak persists, the wax ring may need replacement. Inspect for cracks; if found, the bowl may need replacement. |
| Clogging | Excessive waste; foreign objects; partial obstruction in drain line. | Use a plunger. If persistent, a plumber may need to clear the drain line. Avoid flushing non-biodegradable items. |
