Since having a water softener installed, some of the

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?

***** had previously fitted new taps myself; obviously
a plumber would have done it with all soldered connections
if only to make things difficult for amateur plumbers
in the future?



Maybe I've misunderstood, 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?
