Setup and Installation

This section provides general guidelines for installing your KOHLER Wellworth toilet. Specific details may vary; always refer to the detailed installation guide provided with your product.

Pre-Installation Checks

• Ensure the floor is level and structurally sound to support the toilet's weight.
• Verify that the water supply line is accessible and has a shut-off valve.
• Confirm the rough-in dimension is 12 inches from the finished wall to the center of the floor drain.

Installation Steps

1. Prepare the Area: Remove the old toilet if applicable. Clean the flange area thoroughly.
2. Install Floor Bolts: Insert the T-bolts into the floor flange slots and secure them in an upright position.
3. Apply Wax Ring: Place the wax ring onto the toilet bowl's horn or directly onto the floor flange, ensuring a good seal.
4. Set the Bowl: Carefully lower the toilet bowl onto the floor bolts, pressing down firmly and evenly to compress the wax ring. Do not rock the bowl.
5. Secure the Bowl: Place washers and nuts onto the floor bolts. Hand-tighten, then use a wrench to tighten an additional 1/4 to 1/2 turn. Do not overtighten. Install bolt caps.
6. Install the Tank: Attach the tank to the bowl using the provided tank-to-bowl hardware, ensuring the rubber gasket is properly seated. Tighten nuts evenly until the tank is snug and stable.
7. Connect Water Supply: Connect the flexible water supply line from the shut-off valve to the fill valve inlet on the bottom of the tank. Hand-tighten, then use a wrench for a final snug turn.
8. Turn on Water and Check for Leaks: Slowly turn on the water supply and allow the tank to fill. Inspect all connections for leaks.
9. Install Toilet Seat: Follow the manufacturer's instructions for installing your chosen toilet seat.

Operating Instructions

The KOHLER Wellworth K-3977-96 toilet is designed for efficient and reliable flushing with its Class Five Flush Technology.

Flushing Mechanism

• To flush the toilet, press down firmly on the left-hand trip lever located on the front of the tank.
• The Class Five flushing system delivers a powerful and consistent flush using 1.6 gallons per flush (GPF) to clear the bowl effectively.
• Allow the tank to refill completely after each flush for optimal performance.

Maintenance and Cleaning

Regular cleaning and maintenance will ensure the longevity and optimal performance of your KOHLER Wellworth toilet.

Routine Cleaning

• Clean the exterior surfaces with a soft cloth and mild, non-abrasive cleaner.
• For the bowl interior, use a toilet brush and a non-abrasive toilet bowl cleaner.
• Avoid using abrasive cleaners, scouring pads, or harsh chemicals (e.g., bleach, acid-based cleaners) as they can damage the finish and internal components.
• Periodically check the water level in the tank; it should be at the waterline mark.

Internal Component Care

• Inspect the flapper or flush valve seal annually for wear and tear. Replace if necessary to prevent leaks.
• Check the fill valve for proper operation. If the tank overfills or does not fill, the fill valve may need adjustment or replacement.

Troubleshooting

This section addresses common issues you might encounter with your toilet.

• Weak Flush: Ensure the water level in the tank is at the correct mark. Check for obstructions in the rim jets or trapway. Verify the flapper opens fully.
• Toilet Runs Continuously: Check if the flapper is sealing properly. Adjust the chain length if it's too tight or too loose. Inspect the fill valve for proper shut-off.
• Leaking: Inspect all connections (tank-to-bowl, water supply line) for tightness. Check the wax ring seal at the base of the toilet. Look for cracks in the tank or bowl.
• Clogging: Use a plunger to clear minor clogs. Avoid flushing non-biodegradable items. If frequent clogging occurs, check for partial obstructions in the trapway or drain line.

If these steps do not resolve the issue, contact customer support or a qualified plumber.
