  • Thank You for not running the vent right up the middle of the vanity! You are demonstrating true “Craftsmanship”!
  • @berkeleyboy483
    Excellent job at explaining the details of rough-in plumbing for a bathroom! Best YouTube plumbing video I’ve seen.
  • @maloot11
    That young fella was really good. Great pacing, easy to follow and understand. He is a natural teacher. Great job.

    Finally, real plumber showing it how it really is. That is how it is done Ladies and Gentlemen. Plumbers get dirty. Their expensive tools look like 10 years old - one day after they bought them. There is no glamour in plumbing. Just a hard work. That's why they get paid big bucks. Thank you for showing to all those YouTube "plumbers" how it is really done ! Bravo !!
  • Good job, from a fellow plumber. Suggestion you could put a 3"x2"wye fitting with a 2" street 1/8 bend on the main run to your toilet, in front of the toilet and continue the 2" run up into the wall making the system a combination waste and vent which would allow you to have a better venting system.
  • Dang! Finally someone who not only knows what he’s doing but also well explained. Great job, thanks!
  • Well done young man! I'm 74 years old , i like how you work!
  • Thanks for this video. You do a great job explaining things! Very professional and helpful with all the details.
  • It's always rewarding to witness a master at his craft. Appreciate your time and knowledge. Mudd.

    The is the best commentary ever man nobody out there is doing such in depth step to step process explaining every bit
  • Okay I have definitely subscribed to this guy he seems to be one of the best teachers out there there's a lot of good plumbers out there but they're teaching skills are minimal yeah the explanations here are what fits into my head anyway much appreciated
  • Crazy you are the only one in 1000 videos I've watched on plumbing that has mentioned how to measure 1/4 per foot on a level. quarter bubble. seems simple, and I guessed that is what it was, but honestly this has been a mystery to this DIYer until today. Excellent walk through. I'm subbing

    This is the best video I've seen on roughing in a bathroom. It was a huge help for me with my bathroom renovation. Thank you!!
  • @jct0667

  • You earned it. Watched the whole video. Nice tips. Clear explanations. Thanks. Keep it up
  • @dmope22
    Awesome video. You have a very good knowledge of your trade. Now I can work on my own plumbing. thanks for the explanation.
  • @erickcortez1392
    This video was very informative. Thank you very much keep them coming!
  • I learned more from this than much of what I've looked at. Also, the wet vent arrangement for the shower was interesting, but this tutorial shows some practical plumbing techniques when you're installing underground.
