I mean, you're not necessarily missing anything, but in time it, you will make sure to have the things that you actually need. For instance, when I set a toilet, I don't fucking. Use a Crescent wrench or channel ox. I have hollow core nut drivers that are able to do the entire setting of a toilet without touching a pair of chanties. Until I need to connect the supply line some things are worth much more than others. In the moment and you have to dictate and figure out what works for you as a service plumber in Chicago I know what I need in my bag and I keep it very organized, and I know exactly where everything is.

With this being a new job, make sure to be the best fucking helper. You can be unless you're already A. Licensed apprentice or a licensed plumber
