5.2 Step-by-Step Installation
- Prepare the Bathtub: Ensure the bathtub drain and overflow holes are clean and free of debris. The overflow hole should be between 2" and 2-1/2" in diameter.
- Install the Drain Shoe: Apply plumber's putty or silicone sealant around the underside of the drain flange. Insert the drain flange into the bathtub drain hole from the inside of the tub. From underneath the tub, attach the drain shoe assembly, ensuring the gasket is properly seated. Tighten securely with an adjustable wrench.
- Install the Overflow Assembly: Position the overflow gasket on the back of the overflow plate. Insert the overflow pipe assembly into the overflow hole from the outside of the tub. Align the overflow plate with the overflow hole from the inside of the tub and secure it with the provided screw. Ensure the cable is routed correctly and not kinked.
- Connect the Cable: Connect the 27" stainless steel cable to both the drain stopper mechanism and the PushControl overflow trim. Follow the specific instructions provided with the unit for proper cable attachment and adjustment. The installation tool included will assist with this step.
- Connect to Waste Pipe: Connect the 1-1/2" tubular piping of the drain and overflow unit to your existing waste pipe system. Ensure all connections are tight and sealed to prevent leaks.
- Test for Leaks: Fill the bathtub with water and check all connections for any signs of leakage. Operate the PushControl mechanism several times to ensure the drain stopper opens and closes smoothly.

7. Maintenance
Regular cleaning and maintenance will ensure the longevity and proper function of your Geberit PushControl unit.
- Cleaning the Trim: Clean the polished chrome trim with a soft cloth and mild, non-abrasive cleaner. Avoid harsh chemicals, abrasive pads, or acidic cleaners, as these can damage the finish.
- Cleaning the Drain: Periodically remove the drain stopper and clean any hair or debris that may have accumulated in the drain opening.
- Cable Inspection: Annually inspect the stainless steel cable for any signs of wear or damage. While the cable is Teflon coated for durability, extreme conditions or improper use can cause wear.
