Frequently Asked Questions

Q: How do I prepare the toilet cassette for use?ⓘ

Open the Thetford door and lift the holding bar to take the waste tank out, then slide it clear while keeping it level, tip it slightly, and pull it free completely. Stand it upright, turn the drain nozzle to face upward, add the right amount of toilet fluid, then top up with enough water to cover the tank's base. Turn the drain nozzle back to its resting position, slide the tank back in, check the holding bar has secured it, and shut the service flap.
