FAQs

Is the Twusch insert heavy?

No, it weighs approximately 800g, making it a very lightweight upgrade for your vehicle.

Can I install this on any Thetford toilet?

No, it is precision-manufactured for specific models, such as the C400 or C200 series. Check your specific model before purchase.

Does it require special cleaning chemicals?

Not necessarily; the smooth, nano-sealed surface is designed to be easily cleaned with mild soaps and non-abrasive cloths.

How does it improve water consumption?

The bowl is shaped to optimize flush trajectory, which requires less water to effectively clear the bowl compared to standard plastic bowls.

Will it reduce odors?

Yes, because the porcelain is non-porous, it does not absorb odors like older or scratched plastic bowls.

Troubleshooting

Water leaking after installation

Ensure the sanitary silicone has a complete, air-tight seal around the entire perimeter of the insert.

Bowl feels loose

Verify that the correct model insert was purchased for your specific toilet and re-apply adhesive if necessary.

Setup, Compatibility & Care

Installation of the Twusch requires careful attention to the compatibility of your specific Thetford cassette model. Before purchasing, verify your toilet model (e.g., C400 or C200) to ensure a precise fit.

Installation Steps:

  1. Thoroughly clean and dry the existing plastic bowl area.
  2. Apply a bead of high-quality sanitary silicone along the contact points as directed by the installation manual.
  3. Carefully align and press the Twusch insert into place.
