@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.

Designed this house with everything but the kitchen sink!

Thank you

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.

Been eyeballing those for years. Works everytime:)

Great resource, thanks for doing these

Funny enough I saw a house on Zillow that had a urinal. There weren't and other pictures of bathrooms. Just the urinal.

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

Thank you bery much sir

EXCELLANT VERY CLEAR

What is the code in joint trenching? Can sewer, water, gas and electrical be ran in the same trench?

Thank you!! 👏🙌

Hey man can you do a diagram of recirt piping? Or boiler systems having trouble in that area

Excellent presentation, thank you.

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."

You can use an impact all day on those bands.

passed my journeyman test today!! thanks for all the help ben! -Ben

thanks for the explanation but the drawings help as to understand more

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.

how do you determine the fixture unit in the first place?

Can you explain what it means "above the bottom of the wall furnace"

How do I take your class?

thank you so much, been looking for this answer for a while now.

I’m sizing a propane gas line and table 1215.2 says capacity in thousands of btu per hour not cubic feet.

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.

Re-taking my Wisconsin plumbing exam next week, and I've already realized why failed it by 2 points. I can't thank you enough for all of these

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"?

Do a rolling offset

Shhhessh

How do I go about ordering the quizzes for all the chapters!??

Do you do any classes

Is a sanitary t ok horizontally?

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.

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!!

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..

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.

Thank you for the lesson, and the gift of sharing your knowledge and experience.

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.

Thank you sir, appreciate your time.

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.

The 1 1/4” main for that small residential house is a bit insane lol even though it’s code you’ll never ever see anything more than 3/4” around here where I live

Very nice

Amazing video, super clear, excellent walkthrough! Especially that gotcha regarding not exceeding the total system DFU no matter what the math tells you- I could see that coming up on an exam! Can't wait to see what you've got on DWV and wet-venting, that stuff makes my head hurt...
