Setup and Installation
Before beginning installation, always compare your toilet tank dimensions to the specifications provided to ensure a proper fit. This lever is designed for front-mount toilet tanks.
Components Included:
- 1 x Front Mount Tank Lever
- 1 x Adjustable Bendable Perfect Fit Arm
Installation Steps:
- Prepare the Tank: Ensure the toilet tank is empty and dry. Remove any existing toilet tank lever.
- Insert the Lever: Insert the handle portion of the new Westbrass D4142-01 lever through the front hole of the toilet tank.
- Secure the Mounting: From inside the tank, place the square mounting bale over the threaded shaft of the lever. Hand-tighten the nut onto the shaft to secure the lever in place. The square mounting base helps prevent shifting.
- Attach the Arm: Connect the adjustable brass arm to the lever mechanism inside the tank.
- Adjust the Arm: The solid brass arm can be bent by hand to achieve the precise alignment required for your toilet's flapper chain. Ensure the arm provides enough leverage to fully open and close the flapper without obstruction.
- Connect Flapper Chain: Attach the toilet's flapper chain to one of the holes at the end of the brass arm. Adjust the chain length as needed to ensure a complete flush and proper seal when the flapper closes.
- Test Operation: Fill the toilet tank with water and test the flush mechanism several times to ensure smooth operation and a complete flush. Make any necessary adjustments to the arm bend or chain length.

Operating Instructions
To operate the Westbrass D4142-01 toilet tank lever, simply press the handle downwards. This action will lift the flapper inside the toilet tank, allowing water to flow into the bowl and initiate the flush cycle. Release the handle once the flush begins. The adjustable brass arm ensures a smooth and consistent flush action.
Maintenance
Regular maintenance helps ensure the longevity and proper function of your toilet tank lever.
- Cleaning: Clean the polished brass handle with a soft, damp cloth. Avoid using abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Inspection: Periodically inspect the connection points and the brass arm for any signs of wear, corrosion, or looseness. Ensure the mounting nut remains securely tightened.
- Arm Adjustment: If the flush action becomes sluggish or incomplete, check the bend of the brass arm and the flapper chain length. Re-adjust as necessary to restore optimal performance.
Troubleshooting
Common Issues and Solutions:
- Loose Handle: If the handle feels wobbly or loose, check the mounting nut inside the tank. Hand-tighten it until secure. Do not overtighten.
- Incomplete Flush: If the toilet does not flush completely, the flapper may not be lifting high enough or staying open long enough. Adjust the bend of the brass arm to provide more lift, or shorten the flapper chain slightly.
- Continuous Running Water: If the toilet runs continuously after flushing, the flapper may not be sealing properly. Ensure the brass arm is not holding the flapper open and that the flapper chain has enough slack for the flapper to close completely. Check for any obstructions under the flapper.
