More info for Turgy:
A plumber is a person who fits and repairs pipes and fixtures for water, drainage, or gas systems.
The word comes from Old French plommier meaning a worker in lead. These days lead is something of a no-no in many cases due to the contamination of the water that it holds or which passes through it, but that is from where my dictionary tells me the word is derived. I've just noticed that the word plumber is rather appropriate in that case, the abbreviation for lead being Pb.
FFC inviting me to have a crack at explaining... here the word crack means to have a go at it.
Trying to turn the rusted up nut a crack meant to turn it a tiny bit.
Stringed musical instruments frequently have the note G as one of their strings, but don't get confused with the musical G string. I don't believe there is any relationship to its meaning here - unless FFC can think of one ???
(No FFC, better not even try!)
