    Great video, very easy to learned I learn a lot from you , but you forget to mention aggregate vent and sump pump which were important in the vent pipe sizing. I suggest you make a video just for those to be thorough.

    I'm just curious, one thing I noticed when you sized the laundry room, you ran it in 2"; I take it that being mandatory to discharge from a 2" washerbox trap, into a 3" drain pipe, is a colorado code?
    Ive seen some cowboy installs doing remodels, and surprised they functioned, but I imagine something happened with suds backup to warrant the 3" sizing for a washer box.
    So plumbing everywhere else, 2" is acceptable?
    Thank you for the lesson as always.

    It's hard to find good teaching on youtube like this! Thank you so much for the easy understanding and efficient teaching! I have one quick question here, if a vent pipe section which connect to the water heater directly, since the water heater do not count any fixture unit, so this vent section goes minimum 1-1/4'', am I correct? Thank you in advanced!

    • @BGsPlumbingClass
      @BGsPlumbingClass  2 года назад +1

      The exhaust from a natural gas water heater would fall in the parameters of Chapter 5 and not have anything to do with the water that passes through the tank, and the minimum size of an exhaust is 3 inches. This depends on the BTU/Hr. I hope this answered your question to where it makes sense, if not please let me know.

  • @adinarayanan1990

    Are these valid for high rises or multi story buildings? Because I’ve usually used a 4 inch for WC. Could u explain this if it’s mandatory? All others match my drawings except WC. And we keep separate stacks for soil n waste

    • @BGsPlumbingClass
      @BGsPlumbingClass  3 года назад +1

      Although the code minimum requirement is 3" for a WC, 4" is used often- especially in high rise or multi story situations. 4" is required by code when there are more than 3 water closets horizontally or 4 vertically. 4" will allow for a longer distance without the need for venting (10' as opposed to 6' for 3").

    I’m still having trouble understanding some stuff. I was wondering if you could go over the drawing 4 public use in the study guide. Just confusing myself on pipe sizes inches on the drain and vents. Part that is confusing me is the pipe goes from a 3in to a 4in drain. Then 1 1/2in goes to 2in vent.

    what measuring tool do you used to draw it in such a way to make the drawing 3-d.

    • @BGsPlumbingClass
      @BGsPlumbingClass  3 года назад +1

      The key to isometric drawing is the 30 degree angle. With that being said, a regular 30-60-90 would suit just fine. However if you are wondering about the template I use, it is the Rapidesign isometric template (R-43)

      That is a question that would involve a long answer. I think it would be best explained through a video. I will endeavor to explain within the week. Short answer would be to check the code (UPC 2018 section 706.0) for information on exactly what type of fitting is allowed in each scenario. Sizes are determined by the fixture unit totals and that is mentioned in this video.

      @@zacharydavis7186
      The Journey-level exam will likely not deal in cross sectional area demands, as it is not a cut and dry code requirement as far as which vent is to be sized larger. That would be subject to design preference. Also, the sump and vent off the sump would likely not be a part of the testing because then each exam would have to have a sump- there are multiple exams provided to avoid cheating.

    • @BGsPlumbingClass
      @BGsPlumbingClass  4 года назад

      If you take a look at the section of piping that I was referring to, it was just prior to the water closet being tied in, so 1 1/2" is appropriate- but not realistic (2" pipe more than likely if cast iron due to cost and availability). Great observation!

    I believe you made this a little too simple. As an introduction its great but for passing a test it doesnt include a sump and therefore does not have enough coverage of pertinent code.

    • @BGsPlumbingClass
      @BGsPlumbingClass  4 месяца назад

      At the time of this video, the intention was to teach according to the state journeyman exam where I taught the class. These videos were a result of having to put the classes online during covid. You are correct in your comment that more could be presented. Based on the classroom setting this was intended for, throwing more into the mix would have been counterproductive. I appreciate the comments, and I may add a specific presentation on sumps in the near future.

    • @BGsPlumbingClass
      @BGsPlumbingClass  3 года назад

      Great question! Cross sectional area is a definite concern. This example is not reflective of a whole system but only a portion of a system. Even if this were a complete system, a vent are of (3x) 1 1/2" vents and (2x) 2" vents would be more than adequate to cover the area of the 3" building drain. The total cross sectional area for the venting is roughly 11.5 sq inches and the cross sectional area for the 3" drain line is 7.065 sq inches.

      That is correct. Until the State of California changes their Journey-level exam to reflect sizing via the bathroom group quantification, I am obligated to my students to ensure they have the needed information to successfully pass the exam. You do, however bring up an interesting topic. I will try to do a quick video on sizing using Appendix C 303.3 (based on approval of an engineered method).
