The C223-CS is part of Thetford's C220 cassette-toilet family. It uses an electric push-button flush supplied from the RV's central freshwater tank and a swivel bowl over a removable waste cassette. The manufacturer's exploded drawing identifies its flush valve, controls, bowl, base seal and waste-tank interface.

Check the right model and part
This page is for the C223-CS configuration. The related C222SWE has a built-in flush-water tank and a pump, so its flushing hardware is different. Verify the model on the toilet data badge and compare the bowl and control-panel configuration before ordering.
