5. Setup and Installation
Installation of the KOHLER Veil K-1381-0 toilet requires basic plumbing knowledge. If you are not comfortable with plumbing tasks, it is recommended to hire a professional plumber.
- Prepare the Area: Ensure the water supply to the bathroom is turned off. Remove the old toilet if applicable and clean the flange area thoroughly.
- Install Wax Ring: Place a new wax ring around the toilet flange on the floor.
- Position the Toilet: Carefully lift and lower the one-piece toilet onto the wax ring and flange bolts. Ensure the toilet is level and stable.
- Secure the Toilet: Install washers and nuts onto the flange bolts and tighten them evenly until the toilet is secure. Do not overtighten to avoid cracking the ceramic.
- Connect Water Supply: Connect the water supply line (sold separately) to the toilet's fill valve. Hand-tighten first, then use a wrench for a quarter turn.
- Turn On Water: Slowly turn on the water supply and check for leaks. Flush the toilet several times to ensure proper operation and fill.
- Install Seat: Attach the slow-close seat according to the instructions provided with the seat.

- Full Flush (1.28 gpf): Press the trip lever down completely for a full flush, suitable for solid waste.
- Light Flush (0.8 gpf): Push the trip lever up for a light flush, ideal for liquid waste. This option can save up to 6,000 gallons of water annually compared to traditional 1.6 gpf toilets.

7. Maintenance and Cleaning
Regular cleaning and maintenance will keep your KOHLER Veil toilet in excellent condition.
- Cleaning the Exterior: Use a soft cloth and a mild, non-abrasive cleaner. Avoid harsh chemicals, abrasive pads, or scouring powders, as these can damage the finish.
- Cleaning the Bowl: Use a toilet brush and a toilet bowl cleaner. Follow the cleaner manufacturer's instructions.
- Skirted Trapway: The skirted design makes the exterior easy to wipe clean, as there are no exposed curves or crevices to collect dust and grime.
- Glazed Trapway: The 2-1/8-inch fully-glazed trapway helps prevent clogs and makes cleaning the interior more efficient.
- Seat Care: Clean the slow-close seat with a soft, damp cloth and mild soap. Do not use strong chemical cleaners on the seat.

8. Troubleshooting
If you encounter issues with your toilet, refer to the following common solutions:
- Toilet Not Flushing Properly: Check the water level in the tank. Ensure the trip lever mechanism is properly connected to the flush valve. Verify that the water supply valve is fully open.
- Continuous Running Water: Inspect the flapper or flush valve for proper sealing. Check the fill valve for correct adjustment and ensure the float is not obstructed.
- Leaks: Turn off the water supply immediately. Check all connections for tightness, including the water supply line, tank-to-bowl connection (if applicable for other models, though this is one-piece), and the wax ring seal at the floor.
- Slow Fill: Ensure the water supply valve is fully open. Check the fill valve for any obstructions or debris.
For more complex issues, it is advisable to contact KOHLER customer support or a professional plumber.
