Frequently Asked Questions 

Q: What does this seal do?
It sits between the top flush-water tank and the bottom waste-holding tank, sealing them together and preventing leaks and odours while allowing the waste-blade valve to move smoothly.

Q: How do I install the new seal?

  1. Separate the top and bottom tanks.

  2. Remove the old seal from the groove.

  3. Clean the groove with mild soapy water — no harsh chemicals.

  4. Press the new seal evenly into place.

  5. Apply a small amount of Thetford Seal Lubricant for smooth operation.

Q: Can I use silicone spray or Vaseline to lubricate it?
No , petroleum or silicone products can damage the rubber. Only use Thetford Seal Lubricant, which is safe and prolongs seal life.
