HERRIMAN, UTAH — I should start this article about my recent home-improvement project with several disclosures: I’m not your average homeowner. In fact, I’ve worked in the plumbing industry in Salt Lake City, my hometown, for more than 22 years:

  • I trained and worked with the tools as a plumber for five years.
  • I then worked in plumbing wholesale distribution for a little over a decade.
