4. Installation Instructions
Installation of a bath drain requires plumbing knowledge and tools. If you are not comfortable performing this installation, it is recommended to consult a qualified plumber.
4.1. Required Tools and Materials (Not Included)
- Plumber's putty or silicone sealant
- Adjustable wrench or channel locks
- Screwdriver (Phillips or flathead, depending on overflow plate screws)
- Tape measure
- Hacksaw or pipe cutter (if trimming is required)
4.2. General Installation Steps
- Prepare the Bathtub: Ensure the bathtub's drain and overflow openings are clean and free of debris.
- Assemble the Drain: Connect the overflow tube to the T-fitting and the waste shoe. Ensure all gaskets are properly seated. Hand-tighten connections initially.
- Install Drain Stopper: Insert the drain stopper mechanism into the waste shoe.
- Apply Sealant: Apply a bead of plumber's putty or silicone sealant around the underside of the drain flange (the part that sits inside the tub drain opening) and around the overflow gasket.
- Position in Tub: From inside the tub, insert the drain flange into the drain opening. From underneath the tub, align the waste shoe with the drain flange and secure it with the provided nut, tightening carefully to avoid overtightening.
- Install Overflow Plate: Position the overflow gasket and the trip lever overflow plate over the overflow opening. Secure the plate with the screws provided, ensuring the trip lever mechanism is correctly aligned with the internal stopper rod.
- Test for Leaks: Fill the bathtub with water and check all connections for leaks. Operate the trip lever to ensure the drain stopper functions correctly. Tighten any leaking connections as needed.
Note: Some installations may require cutting the overflow tube or waste shoe to fit specific bathtub dimensions. Measure carefully before cutting.
5. Operation
The Watts 98CP Bath Drain utilizes a trip lever mechanism to control the drain stopper.
- To Close the Drain: Push the trip lever handle down. This action lowers the internal stopper, sealing the bathtub drain opening and allowing the tub to fill with water.
- To Open the Drain: Pull the trip lever handle up. This action raises the internal stopper, opening the bathtub drain and allowing water to flow out.
Ensure the lever moves freely and the stopper fully engages and disengages. If the stopper does not seal properly, check for obstructions or adjust the stopper mechanism if accessible.
6. Maintenance and Cleaning
Regular maintenance helps ensure the longevity and proper function of your bath drain.
- Cleaning the Trim: Clean the chrome-plated trim with a soft cloth and mild, non-abrasive cleaner. Avoid harsh chemicals or abrasive scrubbers, which can damage the finish.
- Clearing the Drain: Periodically remove the drain stopper (if removable) and clear any hair or debris that may accumulate. For clogs further down the drain, use a plumbing snake or a chemical drain cleaner specifically designed for plumbing systems, following product instructions carefully.
- Checking for Leaks: Regularly inspect visible connections for any signs of leaks. Address minor leaks by tightening connections or replacing worn gaskets.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Slow Draining | Hair or debris accumulation in the drain or stopper mechanism. | Remove the drain stopper and clear any obstructions. Use a plumbing snake if the clog is deeper. |
| Drain Does Not Seal | Stopper mechanism misaligned or obstructed. | Check for debris around the stopper. Ensure the trip lever rod is correctly connected to the stopper. Adjust the stopper if it has an adjustment screw. |
| Water Leaks | Loose connections or damaged gaskets. | Inspect all connections (drain flange, overflow plate, T-fitting). Tighten any loose nuts. Replace worn or damaged gaskets. Reapply plumber's putty if necessary. |
| Trip Lever Stiff/Stuck | Corrosion or debris in the lever mechanism. | Remove the overflow plate and inspect the lever mechanism. Clean any corrosion or debris. Apply a small amount of silicone grease if needed. |
