@rustbucket throws a large party every year for his local kitchen fitters because of how they neatly cover his boiler pipework.
I take it you’re another TLB plumber? This cuppeth overfloweth with plumbers, no wonder we can never get one you’re all on here skiving!
The best way to look at plumbers is they are about half way to becoming a heating engineer. But then so are bricklayers
Plumbers always carry a piece of pipe in the van with a nail in, so if their work leaks, they can blame the joiner
Says who? I learnt chimney flashing, and fabrication of up stands at college. Lead welding. Bossing etc from flat sheets. mind you that was a while ago But to answer your specific question, all other trades are inferior to heating engineers. I’m surprised you even had to ask.
