1. Product Overview

The Geberit 151.506.00.1 is a TurnControl cable-operated bath waste and overflow rough-in unit. This unit is designed to manage the drainage and overflow functions of a bathtub. Its unique design positions critical working parts outside the waterway, minimizing the risk of clogging. The high-quality cable is crafted from Teflon-coated stainless steel with a plastic sleeve, ensuring reliable and long-lasting performance.

This rough-in body is compatible with most bathtubs ranging from 17 to 24 inches deep and with wall thicknesses between 1/16 to 5/16 inches. It accommodates 2-inch diameter drain hole openings and 2 to 2.5-inch diameter overflow hole openings. Please note that this product is the rough-in body only and requires a separate Euro or Traditional TurnControl trim kit for complete installation and operation.

Installation of the Geberit 151.506.00.1 rough-in unit should be performed by a qualified professional in accordance with local plumbing codes. This unit is designed for 1-1/2 inch PVC Schedule 40 piping.

3.1 Pre-Installation Checks

• Verify tub compatibility: The unit fits tubs 17-24 inches deep with wall thicknesses of 1/16-5/16 inches.
• Ensure drain hole opening is 2 inches in diameter.
• Ensure overflow hole opening is 2 to 2.5 inches in diameter.
• Confirm all included components are present.

3.2 Installation Steps (General Guide)

1. Prepare the Tub: Ensure the drain and overflow holes in the bathtub are clean and free of debris.
2. Position the Rough-In Unit: Insert the overflow assembly into the overflow hole and the drain assembly into the drain hole from the underside of the tub.
3. Secure Connections: Use the provided fastening material to secure the rough-in unit to the tub. Ensure a watertight seal using appropriate plumbing sealant as required.
4. Connect to Drainage System: Connect the 1-1/2 inch PVC Schedule 40 piping from the rough-in unit to the household drainage system. Use PVC cement for secure and leak-proof connections.
5. Cable Routing: Route the 27-inch Teflon-coated stainless steel cable as per the specific instructions provided with the trim kit. The cable connects the TurnControl mechanism to the drain stopper.
6. Leak Test: After installation, fill the tub with water and check for any leaks around the drain, overflow, and all pipe connections before proceeding with finishing work.

4. Operating Instructions

The Geberit 151.506.00.1 rough-in unit operates in conjunction with a compatible TurnControl trim kit (sold separately). Once the trim kit is installed, the drain is controlled by a rotary mechanism, typically located on the overflow plate.

• To Close the Drain: Rotate the TurnControl knob or lever on the trim kit in one direction (refer to your trim kit's specific instructions for direction). This action will lower the drain stopper, sealing the tub.
• To Open the Drain: Rotate the TurnControl knob or lever in the opposite direction. This action will lift the drain stopper, allowing water to drain from the tub.

Ensure the TurnControl mechanism moves freely and the drain stopper responds correctly. If resistance is felt, do not force the mechanism.

5. Maintenance

The Geberit TurnControl bath waste and overflow system is designed for minimal maintenance due to its robust construction and the placement of critical components outside the waterway.

• Periodic Inspection: Periodically check the operation of the TurnControl mechanism and the drain stopper. Ensure smooth movement and proper sealing.
• Cleaning: Clean the visible parts of the trim kit according to the manufacturer's instructions for the trim kit. Avoid harsh abrasive cleaners that could damage the finish.
• Cable Durability: The Teflon-coated stainless steel cable with a plastic sleeve is designed for long-term, trouble-free service. No specific lubrication or maintenance is typically required for the cable itself.
• Obstruction Prevention: While the design reduces clogging, avoid pouring harsh chemicals or large debris down the drain to maintain optimal performance.

6. Troubleshooting

If you encounter issues with your Geberit bath waste and overflow unit, consider the following common troubleshooting steps:

• Slow Draining: If water drains slowly, check for obstructions in the visible drain opening. While the design minimizes clogs in the cable mechanism, hair or soap buildup can still occur in the drain pipe. Use a plumbing snake or appropriate drain cleaner if necessary.
• Drain Not Sealing: Ensure the TurnControl mechanism is fully engaged to the closed position. Inspect the drain stopper for any debris preventing a complete seal. If the stopper itself is damaged or misaligned, it may need adjustment or replacement (part of the trim kit).
• TurnControl Mechanism Stiff or Not Operating: This could indicate an issue with the cable or the trim kit's rotary mechanism. Do not force it. Check if the trim kit is properly installed and secured. If the issue persists, professional inspection may be required.
• Leaks: Leaks typically occur at connection points. If a leak is detected, immediately turn off the water supply to the tub (if applicable) and inspect all plumbing connections for tightness and proper sealing. Re-sealing or tightening connections may be necessary.

For persistent issues or if you are unsure about performing repairs, it is recommended to contact a qualified plumber or Geberit customer support.
