Sure, no reason not to.
An engineering degree in fluid dynamics would do the trick.
You would take physics
plumber
This depends on what material the plumber uses, what fittings the plumber uses, how much piping will be used and how long the plumber will take.
We have a leaky drain and I need to hire a plumber. How would I go about finding a qualified plumber?
You take a plumbing apprenticeship
If it is " You want to take a class with the best teacher?" then yes. This would be used when in disbelief. If you are just asking it, then you would usually say, " Do you want to take a class with the best teacher?"
A great start would be atrending a 5 year 10,000 hour apprenticeship with 744 hr class room studies and hands on experience and working uder the auspices f a Master plumber for a total of 7-10 years prior to taking your own masters exams.
Before calling in a plumber, it would be wise to try a product such as Liquid Plumber or Drano to unclog your sink drain. Many times it is just a matter of build up in the drain, and these products will take care of that. It is alot cheaper than callin in a plumber.
Yes. I have to in my school.
If you can't figure out how to fix it yourself I would recomend calling a plumber. They will be able to take care of everything.
