About

I’m John Petkovich, the inventor of the M.O.A.B. Hose Bib Wrench. I’ve been working in the plumbing trade since 1987, choosing to go into the trade because I could live anywhere I wanted to and still be able to make a living. Since the beginning, I have done every type of plumbing job you can think of, from repairing a hose bib to plumbing multi-story hospitals.

I have always been a person who strives for success and perfection. Quality and doing it right has and continues to be the most important ingredient in my work.

I also believe in doing work for my customers the same way I’d want them to do work for me. In that case, keeping up with the latest technology has made the quality very well seen by my customers and has also made life easier for me as a plumber. The M.O.A.B. Hose Bib Wrench is a perfect example of that. During my plumbing years, I’ve learned that you can never have too many tools.
