I like the videos of the code. Only thing I would ask if I can get them with out the adds

In other words, csc of 45 degrees is 1.414

Tried to test this with the 3 4 5 method, when I times 3 by 1.412 it doesn’t equal 5 obviously I’m missing something here but not sure what

Do you have a video on how to draw isometric drawings? I can't figure out how to know when to draw the lines N,S,E,W based on your schematic. I need basic Instuction into the basic fundamentals.

I have limited access is there any other way? I’m working in Laguna beach ca. so wondering if it’s code legal

Do you know a method of getting the food vent run when there is limited space? Are there alternatives to having the drain that much lower under the foot vent? I am dealing with drain piping running perpendicular to the floor joists and have limited headroom space. Are there other options?

I like the service you offer it's a game changer for me. Can't find the blank isometrics to practice, any ideas? Taking my WA exam on Friday. Want to have a positive reply for your comments feed. A company is waiting for me to start working next week.

same 60 inch pound on a pvc pipe too???

Does anyone know what to do with Lawn Sprinklers on a sizing chart? Or tell me where to find it in the book.

Your drawings are impressive.

Who is dumb enough to still not turn off the faucet as soon as seeing that the water is not draining from the sink. Who will wait until the water fills the whole sink just to realize there is blockage

The way I learned this method is to put a 45 on your stack and cut a close piece and put your other 45 on so that they are hub to hub. Find the center of that 45, then find the center of where you are going, subtract the 2 then multiply 1.414 and add the 2 hubs. For example, you have your 2 45s hub to hub on your pipe, you pull a measurement of 8 inches to the center of the second 45, you then find your center of where you want to send the offset, let's say it's 24 inches away, subtract 24-8 and multiply 1.414 + the 2 hubs and you will get your piece.

Hot and cold branch sizing is allowed to be based on 75% of the fixture unit value for the individual branch per note 3 on the table 610.3. I noticed you did not size that way which is more complicated. This is a conservative method, but if they look for code minimum, it wouldn't meet that requirement.

Thank you for uploading these videos! I’m supposed to be taking my test within the next few months and have been watching your videos a lot lately. One question, Where did you get that Backflow preventer chart?

Great video very informative and definitely helped me out. Only confusing part but I think I figured out is.. when you add 23.5 and 5.5 you get 29 plus that last hose bib would be 30Fu. Which is under 31.5, so I just wanted to clarify if all is correct the whole goal was to calculate it being under 31.5. Other than that, if you just add the LAST hose bib as 2.5 you would get 31.5 exactly. Which is kind of similar to what the example drawing on UPC 2021 page 146 has, HB-pipe section 33 and 49.

Don’t forget the take of the 45 bend

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?

Can a toilet drain straight down waste line with no bend, but venting above?

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.

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
