Additional installation hardware, such as floor flange bolts and a water supply line, may be required and are typically not included.

4. Setup and Installation

Installation of the Thetford Aqua-Magic Style II RV Toilet typically involves replacing an existing RV toilet. For detailed, step-by-step instructions, refer to the official User Manual PDF provided by Thetford. A general overview of the process includes:

  1. Preparation: Turn off the RV's water supply and drain the system. Remove the old toilet, ensuring the floor flange is clean and ready for the new installation.
  2. Positioning: Carefully place the new toilet onto the floor flange, aligning the bolt holes.
  3. Securing: Use new floor flange bolts (often included with the toilet or purchased separately) to secure the toilet firmly to the floor. Do not overtighten.
  4. Water Connection: Connect the water supply line to the toilet's water inlet. Ensure a watertight seal. Some installations may require a 90-degree elbow fitting for optimal clearance, especially if the water hookup is directly out the back.
  5. Testing: Slowly turn on the water supply and check for any leaks around the base and water connection points. Flush the toilet several times to ensure proper operation and seal.

5. Operating Instructions

The Aqua-Magic Style II RV Toilet features a user-friendly single-pedal flush system.

  • Adding Water: To add water to the bowl, press the foot pedal partially down. This will open the water valve, allowing water to fill the bowl. Release the pedal when the desired water level is reached.
  • Flushing: To flush the toilet, press the foot pedal all the way down. This will open the flush ball and activate the rinse, clearing the bowl. Hold the pedal down until the bowl is clear, then release it to allow the flush ball to close and retain water in the bowl.
  • Water-Saving Hand Sprayer (Optional): If equipped with an optional hand sprayer, it can be used to rinse the bowl with minimal water, contributing to water conservation.

6. Maintenance

Regular maintenance ensures the longevity and proper function of your RV toilet.

  • Cleaning: The smooth china bowl is easy to clean. Use RV-safe toilet bowl cleaners that are specifically designed for plastic and rubber seals to avoid damage. Avoid abrasive cleaners or brushes. The flush valve is designed to wipe clean with every flush, reducing buildup.
  • Seal Lubrication: Periodically lubricate the flush ball seal with a silicone-based lubricant or a product specifically designed for RV toilet seals to maintain flexibility and prevent leaks.
  • Winterization: Before storing your RV for winter, ensure the toilet is properly winterized to prevent freezing damage. This typically involves flushing with RV antifreeze after draining the water system. Consult your RV's overall winterization guide for complete instructions.

7. Troubleshooting

If you encounter issues with your Aqua-Magic Style II RV Toilet, consider the following common problems and solutions:

  • Water Leaking at Base: Check the floor flange bolts for proper tightness. Inspect the floor seal for damage or improper seating. Ensure the toilet is securely mounted.
  • Water Leaking at Water Inlet: Verify that the water supply line connection is tight and that the washer/gasket is properly seated and not damaged.
  • Bowl Not Holding Water: This often indicates a dry or damaged flush ball seal. Lubricate the seal with an RV-safe lubricant. If the seal is cracked or hardened, it may need replacement. Ensure no debris is lodged under the flush ball preventing a complete seal.
  • Weak Flush: Check the RV's water pressure. Ensure the water valve is fully opening when the pedal is pressed.

For more complex issues or if troubleshooting steps do not resolve the problem, refer to the comprehensive User Manual PDF or contact Thetford customer support.
