Thetford's Aqua-Magic Galaxy and Starlite toilets have a shared exploded parts sheet, but their flushing mechanisms changed across production dates. Identify the mechanism and its period before ordering; the valve, seat, hinge and floor-mount parts have separate references.

Check the model before ordering
For the mechanism at callout 5, Thetford distinguishes units produced from 1973 to March 15, 1985, those made until July 14, 1990, and subsequent production. Older toilet mechanisms shown in the drawing may no longer be available. Use the exact original part number instead of matching by the outer shape alone.
