aint the whole priciple of plumbing easyn though, water pipe not working , look for stop cock, is there water there then look for the wet patch and theres the leak, gas leak give a smell when theres a issue and if the boiler dont work start it with a match

when long john silver fitted my boiler the fooker never even noticed the gas supply was comming thorugh at too higher a rate and causing the boiler to shut down

i tried everything to get him backj and at one point was gonna take his horse as hostage, but trigger leged it home

no means to offend but im sure that after ya get the training ect and have a bit of experinece then plumbing does get slightly easier, its more experience aint it
