What we have not checked
We can show you that 618578 is a real Thetford number, what Thetford calls it, and which parts lists carry it. Model compatibility has not yet been confirmed. That depends on your model year, build date and what is actually installed, and we do not publish a compatibility claim until we can show it in the manufacturer’s own document.
