Installation Steps:
- Prepare the Installation Area: Turn off the main water supply to your home. Drain any remaining water from the pipes. Clear the area around the tub and shower wall.
- Rough-in Plumbing: Ensure your wall plumbing is set up for a three-handle, wall-mount tub and shower faucet with standard 1/2" IPS connections. The internal valve hardware should be installed according to standard plumbing practices.
- Install the Faucet Body: Position the faucet body and secure it to the wall using the provided mounting hardware. Ensure it is level and properly aligned.
- Connect Water Lines: Connect the hot and cold water supply lines to the appropriate inlets on the faucet body. Apply pipe thread sealant to all threaded connections to prevent leaks.
- Install Tub Spout: Thread the tub spout onto its connection point. Ensure it is securely tightened and facing downwards into the tub.
- Install Shower Head: Attach the shower arm to the wall connection, applying pipe thread sealant. Then, thread the shower head onto the shower arm. Adjust the angle as desired.
- Install Handles: Attach the three control handles (hot, cold, and diverter) to their respective stems. Secure them with any provided set screws or caps.
- Test for Leaks: Slowly turn on the main water supply. Check all connections for leaks. If leaks are detected, turn off the water, tighten the connections, and retest.

Operation
The Kingston Brass GKB231 Magellan Tub and Shower Faucet features a three-handle design for precise control over water temperature and flow direction.
- Hot Water Handle: Typically located on the left. Turn counter-clockwise to increase hot water flow.
- Cold Water Handle: Typically located on the right. Turn counter-clockwise to increase cold water flow.
- Diverter Handle: Located in the center. Turn this handle to switch water flow between the tub spout and the shower head.
Adjust the hot and cold handles to achieve your desired water temperature. Use the diverter handle to select between filling the tub or using the shower.
Maintenance
Regular cleaning and maintenance will help preserve the finish and functionality of your faucet.
- Cleaning the Finish: Clean the polished chrome finish with a soft, damp cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish. Rinse thoroughly and dry with a soft cloth to prevent water spots.
- Cleaning the Shower Head: Periodically check the shower head nozzles for mineral buildup. If clogged, gently rub the rubber nozzles to dislodge deposits or soak the shower head in a solution of white vinegar and water.
- Washerless Cartridges: The faucet uses durable washerless cartridges, which generally require less maintenance. If you experience persistent drips or difficulty turning the handles, the cartridges may need to be inspected or replaced.
Troubleshooting
Here are some common issues and their potential solutions:
- Issue: Leaking from handles or spout.
- Solution:
- Ensure all connections are securely tightened.
- The internal washerless cartridge may need to be replaced. Turn off water supply before attempting replacement.
- Issue: Low water pressure from shower head or tub spout.
- Solution:
- Check for mineral buildup in the shower head nozzles or tub spout aerator. Clean as described in the Maintenance section.
- Verify that the main water supply is fully open.
- Inspect the water lines for any kinks or obstructions.
- Issue: Handles are stiff or difficult to turn.
- Solution:
- Mineral deposits can accumulate around the cartridge. Cleaning or replacing the cartridge may resolve this.
- Ensure the handle screws are not overtightened.
If these troubleshooting steps do not resolve the issue, please contact customer support or a qualified plumber.
