Setup and Installation
This section guides you through the process of replacing your old toilet trip lever with the new TOTO THU458. No specialized tools are typically required, but a wrench may be helpful for tightening the nut.
- Turn Off Water Supply: Locate the water shut-off valve behind or near the toilet and turn it clockwise until the water flow stops. Flush the toilet to empty the tank.
- Remove Old Trip Lever: Open the toilet tank lid. Inside the tank, locate the nut that secures the old trip lever to the toilet tank wall. Unscrew this nut counter-clockwise. Detach the chain or rod from the old trip lever arm. Carefully remove the old trip lever from the outside of the tank.
- Insert New Trip Lever: From the outside of the toilet tank, insert the new TOTO THU458 trip lever through the hole in the tank wall. Ensure the handle is facing the correct direction.
- Secure New Trip Lever: From inside the tank, place the securing nut onto the threaded shaft of the new trip lever. Hand-tighten the nut clockwise until it is snug. Avoid over-tightening, which can damage the tank or lever. A slight amount of play is normal, as noted by some users, but it should be secure enough not to wobble excessively.
- Attach Flapper Chain/Rod: Connect the flapper chain or rod from the toilet flapper to the arm of the new trip lever. Adjust the chain length so there is a small amount of slack (about 1/2 inch) when the flapper is closed. This ensures a complete flush and proper seal.
- Restore Water Supply: Turn the water shut-off valve counter-clockwise to restore water flow to the toilet. Allow the tank to fill.
- Test Flush: Perform several test flushes to ensure the trip lever operates smoothly, the flapper opens and closes correctly, and there are no leaks. Adjust the chain length if the flush is weak or the flapper does not seal properly.
Operating Instructions
To operate the TOTO THU458 Trip Lever, simply press down on the handle. This action will lift the flapper inside the toilet tank, allowing water to flow from the tank into the bowl, initiating a flush. Release the handle once the flush begins. The flapper will then close, and the tank will refill.
Maintenance and Care
To maintain the appearance and functionality of your chrome plated trip lever:
- Cleaning: Clean the chrome surface regularly with a soft cloth and mild, non-abrasive cleaner. Avoid harsh chemicals, abrasive pads, or polishes that can damage the chrome finish.
- Inspection: Periodically check the connection nut inside the tank to ensure it remains snug. If the handle feels loose, gently tighten the nut.
- Arm Movement: Ensure the arm moves freely without obstruction. If it sticks, check for any debris or misalignment.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Handle is loose or wobbly. | Securing nut inside the tank is loose. | Open tank lid and gently tighten the securing nut clockwise. Do not overtighten. |
| Toilet does not flush or flushes weakly. | Flapper chain is too long or disconnected. | Adjust the flapper chain length to have minimal slack (approx. 1/2 inch) when the flapper is closed. Reconnect if disconnected. |
| Toilet runs continuously after flushing. | Flapper chain is too short, preventing the flapper from sealing. | Lengthen the flapper chain slightly to allow the flapper to fully close and seal. |
| Handle sticks or is difficult to press. | Obstruction or misalignment of the lever arm. | Check inside the tank for any obstructions. Ensure the lever arm is not rubbing against the tank wall or other components. |
