I don't know.

Where would it have been attached? There is no sign of an attachment
place in the top of the WH or the bottom. They are both smooth except
the top has a hole for the input and a hole for the output.

And there is definitely no hole in the top of the WH where one can
unscrew it from the outside and replace it.

I don't think there is any place on the sides either. Do they ever
put it threre?
