Ahaha, most likely the plumber who installed it had a great sense of humor. On the question of whether we found a plumber who works around the clock, I can tell you with certainty that it is virtually impossible. Our country has a shortage of specialists in this field because the profession is not in high demand, even though it has many advantages. I recently read this article https://www.howtobecomeaplumber.org/online-schools/, which describes all the nuances of this profession and where you can get training. I advise you to read it as well.
