Which parts lists carry this number
It appears on the parts lists for 2 different models: Aqua-Magic Residence and Aqua-Magic VI. A number shared across several models usually means the component was carried over between them, which is useful when the exact list for your model is not the one you can find.

What we have not checked
We can show you that 31859 is a real Thetford number, what Thetford calls it, and which parts lists carry it. We have not verified that it fits your camper. That depends on your model year, build date and what is actually installed, and we do not publish a fitment claim until we can show it in the manufacturer’s own document.
