Since having a water softener installed, some of the
Yorkshire fittings***** have a green powdery leakage.

Clearly, the nuts on the fittings need to be nipped up
again, but is the greenness indicative of a high rate of
corrosion in the system due to the salt, or is it just
a reaction to the air once it had seeped?

a plumber would have done it with all soldered connections

Maybe I've misunderstood,Â* Yorkshire fittings are soldered.

Anyway, plumbers seem to use plastic whenever they can.


Perhaps I misunderstood, it being some years since doing
any plumbing myself, but I thought the Yorkshire fittings
were the ones I used, those with a crumpable olive and a
big nut to compress it?

Those are compression fittings:

Yorkshire fittings are a specific type of "capillary" solder fitting
where there is a ring of solid solder built into the fitting during
manufacture. So you can simply clean and flux the pipe, then just heat
the fitting without the need to add solder manually.

They look like:

They make all types.

They do, but generally people refer to solder ring fittings (from any
manufacturer as "Yorkshire") and other fittings (even under the trade
name "Yorkshire") as capilliary, compression, push-fit, etc.
