Thetford C200 cassette toilet model and cleaning prep

Use this Thetford C200 support guide to document cassette model, serial, flush, cleaning, and storage facts before support.

Owner-safe checklist

• Record whether the toilet is C200, the flush type, serial label status, waste cassette condition, cleaner used, and whether the bowl holds water.
• Stop using the toilet if it leaks after freezing, will not hold water, or the cassette will not seat normally; save photos of labels and visible condition.
• Use Thetford support, an authorized service center, or an RV dealer for valve, seal, supply, or parts decisions.
