Setup and Installation
This section outlines the general steps for installing the K-7159 pop-up tub drain. Specific details may vary based on your bathtub model and existing plumbing. Professional installation is recommended.
Tools Required (Not Included):
- Adjustable wrench
- Plumber's putty or silicone sealant
- Screwdriver (Phillips/Flathead)
- Tape measure
- Pipe cutters (if adjusting pipe length)
Installation Steps:
- Prepare the Bathtub: Ensure the bathtub drain opening is clean and free of debris. For above-the-floor installations, confirm adequate clearance beneath the tub for drain connections.
- Install Drain Shoe: Apply plumber's putty or silicone sealant around the underside of the drain flange. Insert the drain flange into the tub's drain opening from the inside of the tub. From underneath, attach the drain shoe assembly, tightening the nut securely to create a watertight seal.
- Connect Overflow (if applicable): If your tub has an overflow, connect the overflow pipe to the overflow opening on the tub and to the brass tee assembly. Ensure all gaskets are properly seated.
- Assemble Pop-Up Mechanism: Connect the pop-up stopper rod to the drain assembly according to the included hardware instructions. Test the pop-up function to ensure smooth operation.
- Connect to House Plumbing: Connect the drain pipe from the tub drain assembly to your existing house plumbing (P-trap). Ensure all connections are tight and sealed.
- Test for Leaks: Fill the bathtub with water and allow it to drain. Carefully inspect all connections for any signs of leakage. Tighten connections as necessary.
Operation
The Kohler K-7159 features a simple pop-up mechanism for controlling water drainage.
- To Close the Drain: Press down firmly on the drain stopper located in the tub's drain opening. It will click into place, sealing the drain and allowing the tub to fill.
- To Open the Drain: Press down firmly on the drain stopper again. It will release and pop up, allowing water to drain from the tub.
Care and Maintenance
Proper care will help maintain the finish and function of your Kohler K-7159 tub drain.
- Cleaning the Finish: Clean the Vibrant French Gold finish with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish. Mild soap and water are generally sufficient.
- Cleaning the Drain: Periodically remove the pop-up stopper to clear any hair or debris that may accumulate. This can be done by twisting or pulling the stopper out, depending on its design. Clean the stopper and the drain opening, then reinsert the stopper.
- Preventing Clogs: Use a drain protector or hair catcher to minimize debris entering the drain, especially if hair is a common issue.
