They seem okay as scenarios to me.
They seem to be picking up on any underlying knowledge required to answer them.
In real life of course it often doesn't work like that.
A Plumber usually has to think on the job, not go home and look in a book.
Its great if you can of course and sometimes you get the opportunity to do so.
Working for small repair companies however, where you don't even know what your next customer will want, it works differently.
If your an employee, your boss will expect you to be able to do what he is paying you for and that means any job in Plumbing.
That means from ships plumbing to oil refinery to tap washers.
You would need a library to cover it all and have the time to read it.
Your head would be so full of information you could probably be so distracted from your often dangerous surroundings you could trip, and hurt yourself.
The key is to do your planning first and then the job, so you don't mix work with learning.
But how do you do that in a small firm when you don't know what sort of job you will be doing in the next half hour let alone day?
Learn as much as you can about how things should work, then you will know why they don't.
And don't be afraid to ask questions or look in kids books for answers.
Have a read of a Physics book, go to one of the junior school websites and learn the basics from the start.
And don't think your too old or sophisticated to do that.
You don't of course have to go down to the sub atomic particle level of matter to understand what your doing, although that helps, but just far enough so that you do understand.
Also what you do sometimes find is that the same principles of Plumbing apply equally to an oil refinery as they do to your house only the pipes are usually bigger.
Wait till you get piece of 24" Spun cast iron to play with. You can get bigger of course, but that is usually the heavy mobs job.
You will spend all day trying to work out how to move it, let alone do anything else with it. And no a nice man with a crane isn't always there.
You have to ask "How deep is the hole, its going in?" "Is the hole properly shored up!"
Loads of questions about none Plumbing things that are all part of Plumbing.
Its all a good laugh. And don't forget to relax and have fun at some point.
