In order to understand how plumbing works, the plumber spends years in school and on the job training in order to be qualified to bring a safe and efficient plumbing system to the public. This channel will provide instructional insights and techniques related to the plumbing and construction industries. There is so much to learn about plumbing and its' many systems. This channel will help explain some of these systems in a way that is both informative and fun. This channel is primarily designed to be used in conjunction with a plumbing program taught by the channel creator where assignments and exams are typically given to coincide with the videos. As this is for instructional purposes, plumbing questions are encouraged and always answered.
Please clarify this for me. Why are you adding the Dish washer hot to the total fixture unit value? You also calculate it when adding the hot? It seems like it is in there twice?
Great question. In this example, the dishwasher is ran as it's own supply. It was done strictly as a sizing example. Much like a dish washer in a commercial situation. In this exercise, I'm also not utilizing the 75% method of supply due to the fact that it was a sample of what the journey level exam uses in the state where I instruct.
rectangle triangles fascinating subject, trigonometric functions is something i do every time ,even when i look at tall building , i try to imagine the value of the hypotenuse from where i stand , adjacent leg and opposite
@0:59 you say you already cut out that gal pipe. Exactly how square does that cut need to be ? I will be uncomfortable, in a tight space, on my back, using either a sawzall or an angle grinder. Helpful hints and tips appreciated.
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.
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.
I know. I felt awful after posting it! I redid the video as revised, reposted it, and the results were the same. No sizes were altered in that error. But I really couldn't believe I did that.
BG - I'm not a plumber. I'm a lay tenant. I have two questions: A. Moen claims their discontinued 1960 Moen 2215 Single Handle 1225 Cartridge Non-Pressuring-Balance Valve will discharge 10-GPM maximum of hot and cold water @ 120-PSI from the Moen tub-spout and 8-GPM maximum (12.35% less) of hot and cold water @ 120-PSI from the shower-arm (only 2.5-GPM hot and cold from a showerhead rated such). B. Per the 2022 UPC (Section 610.3, Table 610.3, and Appendix A), I made the below Hunter's Curve calculations for our 8-Unit 1906-built but 1960s-1970 upgraded fixtures Apartment: 1. 87.50-WSFUs for 36 Fixtures (8 of which are bathtubs/showers) 2. 87.50-WSFUs converts to 40 GPM (rough estimate) 3. 300-GPH Hot Water Tank C. Is the 10-GPM flow rate correct based on a 40-GPM water supply -- but only for the cold water supply, for up to 4 of the 8 tub-spouts at the same time (10 x 4 - 40-GPM)? D. Is the 8-GPM flow rate incorrect based on the 300-GPH Hot Water Tank -- only 5 of the tub-spouts, only 5 of the shower-arms, or any 5-combination out of 8 (8 X 5 - 40-GPM)? I assumed I can't convert the 4-WSFU assigned to each bathtub/shower into a 4-GPM hot and cold flow rate for each -- correct? Thanks! I hope you can answer my lay (non-plumber) questions.
In many cases, an "eyeball estimation" is acceptible. When running offsets of longer than 4' in an exposed area, using a less forgiving material such as cast iron, a minute of time on a scratch piece of paper or a construction calc app on the phone will save material, time, and inaccurate installation.
Oh, absolutely! In this video, I only show where the constant comes from. It was the first video I posted and recorded for RU-vid. I had to do a short video with captioning for a certification I was working on.
@@BGsPlumbingClass oh ok thanks for showing me man. I wanted a easier way instead of laying it out on the ground or eye balling it because I work in high rise residential it’s all about speed and not Wasting time lol.
Stubbing to a p-trap for a laundry sink long sweep or 90 elbow considering the Santee is 14 inches away? This fitting would be considered horizontal to horizontal and 1-1/2 fitting. Thanks
I’d like to know why you added 1.5 on this dish washer because table 610.3 say kitchen sink with or without dish washer is still 1.5 but on the video you counted 3.0
Great illustration, thank you! One question for you. How does footnote 3 from Table 610.3 come into play? It is in the CA Plumbing Code which is based on the UPC. I believe this footnote should also be in the UPC. "3 The listed fixture unit values represent their load on the cold-water building supply. The separate cold water and hot water fixture unit value for fixtures having both hot and cold-water connections shall be permitted to be each taken as three-quarter of the listed total value of the fixture."
Milwaukee has developed a specific torque rated cordless drill that I can safely say works well. However, an older impact drill could bind the bands up and either lock it up prior to proper torque, or break the band all together. I've had too many of my crew over the years break bands
This video is good but a little misleading...the code states that we are to use the full fixure values listed in the UPC code book to size the cold water supply to the house as well as to size the meter, however, what the video is not telling you is that when sizing individual hot OR cold interior sections of water piping, you indeed can reduce the listed fixture value by 25% for any fixture that has both hot water and cold water going to it. In other words you can multiply the fixture unit by 75%. This can drastically reduce the sizes of different sections of your water system.....And you will not starve any of your fixtures of water by using this method as its in the code book.
You are absolutely correct about the 75%, and on top of that, you could even size according to bathroom groups. The purpose of the video was to go over the basic sizing parameters based on the journeyman exam for the state of California. The exam does not cover the 75% method, which is note 3 in table 610.3 I appreciate the feedback, and thank you for bringing up this additional option.
Redundant bump for algorithm purposes, and to say I like transition glue for pvc to pvc, I'd use it always if it was cost effective. The viscosity is more forgiving, plenty strong, and I like the green joints; no pun intended.
at 18:35, you show a vent being offset horizontally with long sweep 90s before it gets 6" above the flood level rim. Isn't this a direct violation of the very first part of 905.3? Don't you have to use 45s to offset below flood level rim to keep it within the definition of "vertical"?
That's a great question! So, if structural conditions prohibit vertical means, then an offset using drainage fittings can be used. The first sentence in 905.3 states "Unless prohibited by structural conditions..." That is the justification for such an offset. Again, great question, I hope I was able to clarify this for you.
I have been instructing plumbing for over 23 years. I got out of the field to teach full time a little over two years ago. If you wanted to know if I do online classes, the answer is not at this time, but I do have a Canvas course written and ready to go. I just need to get off my tush and commit already. I'm looking into beginning that en devour in the summer.
Thank you Ben. A part of me knows I should want to be on the administration/office side, but the rest of me would rather be meticulous and installing. I do get purpose from knowing I gave a good product to the customer, that will probably operate for longer than they will; barring any manufacturer defect, or natural disaster. I bet a couple bucks my install will survive a reasonable earthquake! Settle down there, ego.
There's nothing wrong with confidence, as long as there's experience and knowledge behind it. I completely agree with you on the continuing to install passion. I realized my greatest joy was seeing my influence on others successes. That's why I decided to instruct full time, more rewarding for me at the end of the day.
Thanks Ben. Your patience and purpose are true gifts; and even more so given the state of things, and how difficult it can be. I hope I'm not making it weird, it's just the way I feel.
Thanks a bunch, Ben. Really wish I would have truly invested in the science of measurement when I was starting; you know its the smart thing to do, but you don't do it... AARRRRGGGGG!!
I get so much push back from individuals that think it's better to just throw up a tape measure. What if all you have is a couple points? Plus, if you have the exact measurements at your immediate disposal, it just makes more sense to me to be perfect when given the opportunity. I think Vince Lombardi said "Strive for perfection, accept excellence" or something like that.
And then fussing with makeup, long pieces, tight spaces above duct work in a joist bay at the rim of a house; the numerous environments that pop up, that aren't a rigid bump number right in your face. I definitely have some frustrated memories, of seeing how much easier, and time saving, it would have been to measure center to center on any type of pipe, and familiarize myself to the dimensions of the fittings I used day in and day out.
If you push plumbing to its capability, it truly is amazing how much you can make the job go easier, with a center to center measurement. One reason why I make my layout marks so large, so they're still there for all to see after I drill the hole, and me to measure with. Save a bunch of sketchy ladder ballet, or recessed number acquisition frustration.
Thank you Ben. This is why I like just sticking to larger residential projects. Colorado inspectors want to see 3" vents always, at 16" off roof, builders want as few penetrations as possible, so you gotta do the song and dance while basically not saying, "I'm not running this whole run to tie the house together, just to save a roof jack and curb appeal." I personally like seeing plumb vents, gives character!! And tells a story on what you got going on.
No apologies needed. We aren't artists, for the reasons we are plumbers; and honestly, your drawings by and large, are better than most I've been presented. Thanks Ben.
Plastic bags flying, American beauty, Clogging storm drains, flooding the city. Maintenance man, stuck inside the t.v, Unaware, the impending flood, in his vacinity. Maintenance, people!! Check those drains!! Get it before it becomes a catastrophe, and AAALLLLLLLL this drywall has to come out. Thank you Ben.
Thank you for your gift of sharing, Ben. And dum dums, read this. To those goof balls, with their pointless complaining, acting like you owe them something, pardon my language but they can just **** right the **** off, those smarmy ****s; your ignorance shows through your shortsightedness. This man is teaching, if you found more information through experience, then huzzah for you; there are others who still need the fundamentals of how you actually aquire the number, and know how it works. This number gets you close, and then you know what to subtract depending on what brand and/or material you are using for further/future efficiency. MAKE SURE THE TWO 45'S YOU HAVE ARE THE SAME BRAND. Pardon and forgive my language, but it seemed needed to be said. I do not appreciate those attitudes, AT ALL. I know we should just ignore people like that, but there's the lesson for them too. UGH.
I understand from a cost standpoint, but just piping a separate trap under the sink drain with stacked santee's, and dumping the dishwasher discharge in its own standpipe just seems the ideal setup; not impeding on the sinks drain rate in the event you are running both your sink disposal side, and dishwasher simultaneously. Why isnt that just the code? Thank you for the lesson, I really appreciate it. And that's a hehe. The dreaded cruise control behind the wall fixture supply piping. Been there. Gotta love them 10p.m days. I really did a number running some in series high temp baseboard; i dont even remember how I messed it up, but I remember that I did. I think I completely missed some rooms with limited materials, and it was in a absolute less than desirable dirt crawlspace on a mountain. "You still at the job??" Yeah, but I'm off the clock..
To expand a bit on Ryan's statement of a back up, the dishwasher is not allowed to be directly connected to a trap under the sink. It has to be an indirect connection. So, tying it to its own trap- if I'm reading it right- will only create some serious issues down the line.
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.
To comment on that toilet picture, we don't know if the guy who laid out the rough in, was the guy who installed it; you know it bothers the installer, and they never forgot it. And they weren't allowed to fix the rough in. Been there, done that. Thank you for the lesson, it is a gift that is very appreciated.
Thank you a bunch sir, appreciate it. I'd try to throw the word "code" in, might be good for more exposure in search results? This is a solid resource, it just needs to get to the plumbers looking for it. I honestly looked more than a few times for plumbing curriculum, and it never popped up for me. Frustrated with the provided results, "reality" t.v format sponsored by monster energy clickbait, I settled for gas furnace trouble shooting To broaden my understanding and be learning something; and then your channel popped up in my suggested videos. Go figure, finally.
It's worth a try. The professional atmosphere you offer, while yet being casual, is definitely more conducive to the learning process than much of what else I've filtered through. The only other objective criticism I can give is, the audio chop. When you turn the volume up, to drown out the distracting, annoying banter of our loved ones, you get that static. It's outside my wheelhouse, but I wonder if there is a way to preserve the video, while filtering it out. I am absolutely willing to grin and bear it personally, but people sure can be persnickity. Obviously something only to think about, when things are slow. At any rate, grateful for what you're giving, thank you Ben.
Indeed, thank you. There is a huge lack in plumbing education representation, in comparison to the other trades. Which I just don't understand. Every city, or town I've looked, they need plumbers.
