They seem to have a finite life-time: we had two of these, bought at
the same time, self-immolate the way you describe within months of
another, after ~5 years of good service.

We asked TW about it and they said it would cost more to get it fixed
than just get a new one -- then again, they would have said that,
wouldn't they. If you figure out how to re-suck the vacuum, do tell the
list!

Cheers

P.S. Sorry, we don't have an adaptor -- you probably figured :)
