Yes
I started in 1978 a full apprenticeship and got C&G advanced craft in Plumbing.
Working yesterday with my new apprentice, and just before we turned the water back on I said "have you double checked all your fittings are soldered or tightened" ......... Yes he replied, so I got him to turn on the water, we got a leak............... a compression nut I forgot to tighten!
He got the blame though........ I said he should have checked mine too.
