Setup and Installation
Tools Required:
- Adjustable wrench or pliers
- Screwdriver (Phillips or flathead, depending on existing hardware)
- Rag or towel
- Bucket (optional, for catching water)
- Plumber's putty or silicone sealant (if replacing the entire drain assembly, not just the rod/strap)
Installation Steps:
- Preparation: Turn off the water supply to the sink and drain any remaining water. Place a bucket under the drain to catch any drips.
- Remove Old Assembly:
- Locate the pivot rod nut on the drain tailpiece under the sink. Loosen and remove this nut.
- Carefully pull out the old pivot rod and stopper.
- Disconnect the old lift rod from the strap and remove the old strap.
- Clean Area: Clean any debris or old sealant from around the drain opening and the pivot rod opening.
- Install New Strap:
- Attach the new LASCO strap to the pivot rod of your existing pop-up stopper mechanism. Ensure it is securely fastened.
- Connect Lift Rod:
- Insert the new lift rod through the faucet body opening.
- Connect the bottom end of the lift rod to one of the holes in the new strap. Choose a hole that allows the stopper to fully open and close.
- Secure the connection, typically with a small screw or clip, if provided with your stopper mechanism.
- Test and Adjust:
- Operate the lift rod to ensure the drain stopper moves freely and seals properly when closed.
- If the stopper does not seal or open correctly, adjust the connection point on the strap until optimal operation is achieved.
- Final Check: Turn the water supply back on and check for any leaks around the drain assembly. Tighten connections if necessary.
Note: If you are replacing the entire drain pop-up assembly, additional steps involving plumber's putty and tightening the drain body will be required. This manual focuses specifically on the lift rod and strap component.
Operating Instructions
To operate the lavatory drain stopper using the LASCO 03-4669 Lift Rod and Strap Assembly:
- To Close the Drain: Push the lift rod down. This action will lower the pop-up stopper into the drain opening, sealing it to retain water in the sink.
- To Open the Drain: Pull the lift rod up. This action will raise the pop-up stopper, allowing water to drain from the sink.
Ensure the rod moves smoothly and the stopper fully engages in both positions.
Maintenance
Regular maintenance helps ensure the smooth operation and extends the life of your drain assembly:
- Cleaning: Periodically clean the visible parts of the lift rod with a soft cloth and mild soap. Avoid abrasive cleaners that can damage the chrome finish.
- Check for Debris: If the stopper mechanism becomes sluggish, remove the stopper and clean any hair or debris that may have accumulated around the pivot rod or inside the drain.
- Lubrication: If the pivot rod feels stiff, a small amount of plumber's grease can be applied to the pivot ball to improve movement.
- Inspect Connections: Occasionally check the connection between the lift rod and the strap, and the pivot rod nut, to ensure they remain tight and secure.
