This is when you talk about your record of getting things done. Go into specifics from your résumé and portfolio; show an employer your value and how you’d be an asset.

Suggested answer: “I’m the best person for the job. I know there are other candidates who could fill this position, but my passion for excellence sets me apart from the pack. I am committed to always producing the best results. For example…”

10 :: Tell me have you ever plumbed an office building?

No but I have worked with steel both in college and on site which I imagine will be the material used.

11 :: Do you know what is Pipe Dope?

A pipe dope is a pipe joint that is used to create a watertight seal.

A broken water line out in the yard may include an excessively high water bill, puddles in your yard or the sound of running water when no faucets or appliances are using water. Blue Mountain can pinpoint the problem without needless trial and error destruction of working pipes. In many cases we can fix the problem right away and save you money.

15 :: Do you know low Flush Toilet Problems?

You might buy a better flushing toilet for your situation. Some air assisted toilet flush well. When the low gallonage gravity toilets first came out I replaced a couple of new Kohler Wellworth Lites with the Am.Std. air assist toilet with good results. That was then and this is now. Today most brands of gravity toilets flush well (including the redesigned Kohler Wellworth models). Power assisted toilets tend to be noisy and frankly, today I definitely do not recommend power assisted toilets.
By the end of 1999 (most brands of U.S. made) gravity toilets manufactured were flushing fine. At the end of 2000 my guess is that over 85% of 1.6gpf toilets flushed well.

16 :: Please explain do you prefer PVC or copper for piping?

PVC is definitely a better choice, since copper pipes tend to rust, heat up and are time taking to install in contrast to plastic piping that is easy to install, has greater insulation and is rust proof.

To me, there is no worst thing I've had to do. I've had a lot of dirty days as a plumber, but it is my job and to me there is no one job that was worse than any other job.

18 :: Explain me what do you enjoy most about being a plumber?

I enjoy making the customer happy, but what I enjoy the most is overcoming a challenging problem and fixing and correcting whatever the problem may be, its a great feeling.

19 :: Tell me is there any other trades you are looking to learn?
