I just had a salamander corrosion guard for use in a central heating
system delivered. It seems to be a used unit to me.
I queried it and was told they "are all like that".
Is that correct? The deposits in both ends of the thing look much more
in daylight that in these pics - but the flaky plating is quite bad -
not that that affects the functioning of course. I can see green
discolouration and even some white on the threads which seems like
limescale. Appreciate some expert yes/no on this. tia
Here are some links to pics of the unit:-
(Well known) Supplier said, verbatim, "I can confirm that they are all
like you have described, the green / white deposit is just from the
mixture of metals.
Had another look - there is definitely verdigris in the nut threads
and the unit is made of chrome plated brass. Also the business part of
the internal nut threads have only a little plating left on them - can
see the brass - as "wear" as if have been tightened up.
Think I'll ask for a replacement.

The supplier. (emailed sales@ as was the only email I found)
Ah - don't know the answer to that.
Not as such - but there is failure of the plating (some "bubbling" on
most all the edges of the nut surfaces adjacent to the weld to the
Right - there are no marks on either olive nut and they have a
different finish to the rest of the thing.
I don't want to look a complete dork by accusing them of sending a
used one - but it really does look as if it has been.
I was wondering about the blueing on the body. Plating and welding
are not good bed fellows. If it had been properly installed I'd
expect marks or "bruising" on at least a couple of the nuts corners.
I think your best course is to call the manufacturers or find an
email address and maybe send the pictures with the query.
