3. Operation

The holding tank blade functions as a seal between the toilet bowl and the waste holding tank. When the toilet is flushed, the blade opens to allow waste to pass into the tank and then closes to create an airtight and watertight seal, preventing odors and leaks. Ensure the blade operates smoothly and closes completely after each use.

4. Maintenance

Regular maintenance extends the life of your toilet blade and ensures optimal performance.

• Cleaning: Periodically clean the blade and its sealing surfaces with a mild, non-abrasive toilet cleaner. Avoid harsh chemicals that can damage rubber seals.
• Lubrication: Apply a silicone-based lubricant specifically designed for toilet seals to the blade's moving parts and seals every few months or as needed. This helps maintain smooth operation and prevents drying out of seals.
• Inspection: Regularly inspect the blade for signs of wear, cracks, or damage. A worn blade can lead to leaks and odors.
• Winterization: If winterizing your RV or motorhome, ensure the toilet system, including the blade, is properly drained and protected from freezing temperatures according to your vehicle's manual.
