Setup and Installation

This section outlines the steps for replacing the canister valve assembly. Tools typically required include a sponge or towel, and possibly a wrench for the water supply line.

  1. Turn Off Water Supply: Locate the water supply valve for the toilet, usually on the wall behind or near the toilet. Turn the valve clockwise until the water supply is completely shut off.
  2. Flush Toilet: Flush the toilet to drain the tank. Hold the flush lever down until as much water as possible has drained from the tank. Use a sponge or towel to remove any remaining water from the tank.
  3. Disconnect Supply Line (if necessary): If the canister valve assembly requires removal from the bottom of the tank, you may need to disconnect the water supply line from the fill valve. Place a small bucket underneath to catch any residual water.
  4. Remove Old Canister Valve Assembly: Depending on your specific Kohler toilet model, the canister valve assembly may twist off, unclip, or be secured by nuts from underneath the tank. Carefully follow the removal procedure for your toilet model. Remove all old gaskets and seals.
  5. Clean Tank Base: Thoroughly clean the area where the canister valve assembly sits at the bottom of the toilet tank. Remove any mineral deposits or debris to ensure a proper seal with the new components.
  6. Install New Canister Valve Assembly: Assemble the new canister valve components according to the specific design of the Kohler 1227235 kit. Place new gaskets and seals as instructed. Carefully position the new assembly into the tank opening and secure it. Ensure it is seated correctly and tightened appropriately to prevent leaks, but do not overtighten.
  7. Reconnect Supply Line (if necessary): Reconnect the water supply line to the fill valve, ensuring a hand-tight connection, then a quarter turn with a wrench.
  8. Restore Water Supply: Slowly turn the water supply valve counter-clockwise to restore water to the toilet tank. Check for any leaks around the new assembly and the supply line connection.
  9. Test Flush: Allow the tank to fill completely, then flush the toilet several times to ensure proper operation and check for any leaks or issues with the flush mechanism.

Operating (Post-Installation Check)

After installation, proper operation is indicated by:

  • The toilet tank filling to the correct water level without continuous running.
  • A complete and efficient flush when the lever is actuated.
  • No visible leaks from the tank or connections.
  • The flapper or seal closing completely after a flush, preventing water from continuously flowing into the bowl.

Maintenance

Regular maintenance helps prolong the life of your canister valve assembly:

  • Periodic Inspection: Annually inspect the canister valve seal for wear, cracks, or mineral buildup.
  • Cleaning: If mineral deposits accumulate, turn off the water, drain the tank, and gently clean the valve components with a soft brush and a mild, non-abrasive cleaner. Avoid harsh chemicals that can damage rubber seals.
  • Seal Replacement: The flapper or seal is a wear item. If you notice the toilet running intermittently or ghost flushing, the seal may need replacement.

Troubleshooting

ProblemPossible CauseSolution
Toilet runs continuously or "ghost flushes"Worn or dirty canister seal; improper seating of the canister valve.Inspect and clean the canister seal. If worn, replace the seal. Ensure the canister valve is properly seated and secured.
