4. Installation
This section outlines the general steps for installing the Kohler Wellworth K-4467-7 toilet tank onto a compatible toilet bowl. Refer to the detailed installation guide packed with your product for specific instructions and diagrams.
4.1 Preparation
- Ensure the toilet bowl is securely installed and the floor flange is properly sealed.
- Confirm the rough-in measurement is 12 inches.
- Gather necessary tools: adjustable wrench, screwdriver, level, and a new toilet supply line (if needed).
4.2 Tank Installation
- Carefully place the tank onto the toilet bowl, aligning the three pre-installed bolts with the holes on the bowl.
- Ensure the tank gasket is properly seated between the tank and the bowl.
- From underneath the bowl, hand-tighten the nuts onto the tank bolts.
- Using an adjustable wrench, tighten the nuts evenly, alternating between bolts, until the tank is secure and level. Do not overtighten, as this can crack the ceramic.
- Connect the water supply line to the fill valve shank on the underside of the tank. Hand-tighten, then use a wrench for a final quarter-turn.

4.3 Water Supply Connection
- Turn on the water supply slowly and check for leaks at all connections. Tighten any leaking connections slightly until the leak stops.
- Allow the tank to fill. The fill valve will automatically shut off when the tank is full.
5. Operating Instructions
The Kohler Wellworth K-4467-7 Toilet Tank operates with a simple gravity flush mechanism.
- To flush the toilet, press down firmly on the flush lever located on the side of the tank.
- The canister flush valve will lift, allowing 1.28 gallons of water to flow into the bowl, initiating the flush.
- Release the flush lever. The canister valve will reseal, and the tank will begin to refill automatically.
This high-efficiency design ensures effective waste removal with minimal water usage.
6. Maintenance
Regular maintenance will help ensure the longevity and optimal performance of your toilet tank.
6.1 Cleaning
- Clean the exterior of the tank with a soft, damp cloth and mild soap. Avoid abrasive cleaners or scouring pads, which can damage the finish.
- For interior cleaning, use non-abrasive toilet bowl cleaners. Do not use in-tank drop-in cleaners containing harsh chemicals, as these can damage internal components and void the warranty.
6.2 Internal Components Check
- Periodically inspect the fill valve and flush valve for any signs of wear or damage.
- Ensure the flush chain has proper slack (approximately 1/2 inch) to prevent continuous running or incomplete flushing.
- Check the tank bolts for tightness annually. Retighten if necessary, but avoid overtightening.
