Installation Instructions
Proper installation of the Thetford TH08975 mounting package is crucial for the secure and leak-free operation of your RV toilet. Follow these steps carefully:
- Preparation: Ensure the water supply to the RV is turned off and the existing toilet (if any) has been removed. Clean the floor flange area thoroughly, removing any old wax or debris.
- Positioning the Mounting Ring: Place the new mounting ring (wax ring or rubber seal) over the existing floor flange, ensuring it is centered and aligned with the bolt holes.
- Inserting Mounting Bolts: Insert the mounting bolts through the designated holes in the floor flange and the mounting ring.
- Positioning the Toilet: Carefully lower the compatible Thetford Aqua Magic Galaxy or Starlite toilet onto the mounting bolts, ensuring the toilet base aligns with the bolts and the mounting ring. Press down firmly to create a seal.
- Securing the Toilet: Place washers and nuts onto the mounting bolts. Hand-tighten the nuts initially, then use a wrench to tighten them evenly, alternating between bolts to prevent cracking the toilet base. Do not overtighten.
- Connecting Water Supply: Connect the water supply line to the toilet's water inlet. Ensure all connections are secure to prevent leaks.
- Testing: Turn on the RV's water supply and check for any leaks around the base of the toilet and the water connection. Flush the toilet several times to verify proper operation and seal integrity.

Operation
Once installed, the mounting package facilitates the secure and stable operation of your Thetford Aqua Magic Galaxy or Starlite toilet. Refer to your specific toilet model's manual for detailed flushing and usage instructions.
Maintenance
Regular maintenance of the mounting package components helps ensure longevity and prevent issues:
- Periodically check the mounting bolts for tightness. Do not overtighten, as this can damage the toilet base.
- Inspect the seal around the toilet base for any signs of leaks or degradation. A compromised seal may require replacement.
- Clean the area around the toilet base with mild, non-abrasive cleaners to maintain hygiene and prevent material degradation.
Troubleshooting
If you encounter issues related to the toilet's mounting, consider the following:
- Leaks at the Base: If water leaks from the base, the mounting bolts may be loose, or the seal (wax ring/gasket) may be compromised. Tighten bolts evenly or replace the seal if necessary.
- Loose Toilet: If the toilet wobbles, check and tighten the mounting bolts. Ensure they are snug but not overtightened.
- Water Connection Leaks: Ensure the water supply line connection is tight and the washer/gasket is properly seated. If leaks persist, the connection may need to be re-sealed or replaced.
