Thetford waste treatments holding-tank prep
Use the official Thetford waste-treatments product group to pick the right holding-tank treatment family and document what was used before support contact.
Owner-safe checklist
- Record the RV toilet model, holding-tank size if known, treatment product name, dose, temperature, storage state, and odor or clog symptom.
- Save photos of the product label, tank-treatment package, and safe visible toilet or cassette model label or paperwork.
- Use Thetford support or qualified RV service for persistent odor, leakage, backup, damaged seals, or sanitation-system parts beyond normal owner cleaning.
