This guy is doing the Lord’s work, I tell ya... what an incredible resource.
I know right! He's amazing
Wow! This is among the best-produced and thorough youtube videos I've ever watched. I'm preparing (watching lots of videos and reading plumbing books!) to replace my entire DWV stack and the bathroom fittings in my 1920 house. As soon as I can scrape together $50 for your ebook, I will definitely buy it. Again, great video.
As a master plumber in Colorado and Washington I stand by this video. Thank you for giving folks this info.
Master Plumber in WA?
B-boo Duffy my apologies that some of us don't have all day to sit here and type the exact names for their licences for you. I'm a contractor in Washington state, I hold a C36/C20 in California, and am a Master plumber in Colorado. Currently working in Colorado Springs. Would you like my blood type as well?
Username checks out. All I need is your shop's name.
The Whole Truth and Nothing But ... combo ... Journeyman Plumber here .. peace ✌️
Matthew AZ boy same to you brother
Thanks. I was getting ready to convert a single sink drain into a double and I think you just saved me a headache.
Awesome! Laymans description of what to use. This will be quite helpful when I get to the plumbing portion of my house build.
Thanks for posting this - best I've seen so far. I'm not a plumber, but I like to know what's going on so I can make sure work is done right when plumbers do it, and for easier tasks, when I do it.
recently corrected plenty of these mistakes in a house a bought and currently doing a full house remodel. as well as added more venting. Before they decided that the waist pipe going from upstairs to down stairs needed more venting so they just drilled 3/4 inch holes on top of the pipe... you cant make that shit up. they tried to make the upstairs sink and shower drain uphill into the main which of course doesnt work. They used Ts instead of wyes or combos, used short radius 90s instead of long radius, ran to small diameter piping in places and went from 1 1/5 down to 1 1/4 from a banch to the main. found several joints incorrectly mated. decided glue was all it needed. lacked true supporting of piping which had sagged over time. a lot of which wasnt noticed until you removed the 3 foot of insulation off of it, or pulled the drywall to see it. Or well lack of drywall and more paneling. Even the domestic water was a mess, PVC main, switch to cpvc to copper back to cpvc, back to copper. ripped it all out except the main, added a true main shut off inside the house back at the point it comes out of the ground. I know some will boo and hiss, but i went with pex as a replacement. In union commercial construction anyway. Most of the guys were telling me why not copper, pex isnt real plumbing. I said The price. Im doing it out of pocket, copper is nice and i dont mind it when im not paying for it. but I couldnt justify using copper in my house do to the price. so I went with pex and used the copper crimp rings vs the stainless pinch ring. No shark bites, ive seen those fail to offend. I have used the caps for temporary while testing or getting some plumbing working to at least have running water. I was going to use a pex manifold but for this house i couldnt justify the cost of one. but none the less i did install isolation between upstairs and down stairs as well as a shut off before and after the water softener and water heater. Might be over kill but if something happens i want to have control quickly.
There's a saying about the person that did the plumbing before you, "They know enough to be dangerous". Lacking Common Sence.
This is the first video of yours I've seen, fantastic information and providing things free is above and beyond, sir. Thank you and Godspeed Mr. Spitz!
Former Montana state plumbing inspector, it would be nice to see more videos like this. So many homeowners wanting to do their own work get it wrong and wind up spending three to four times the cost. And when in doubt, call your local inspector. They are more than happy to come out and look and it WON'T COST A DIME! Better to be safe than have a real mess in the end.
based this is the way
Most inspectors are to nice, so most people don't reach out. I did some plumbing on my house. Had it inspected, it wasn't vented right. I asked him what was wrong and how to fix it. He said I ain't your contactor and walked off.
@@cfg7523 yep.. moral of the story, hire a professional plumber so it won’t cost you time and having to do it all over again in the future.
Here in va inspectors cost a TON of money
i’ve seen a couple of videos from out east were inspectors are helpful and come by to help you as you go. I did not have that same experience here in Kansas. I actually made a TH-cam video with a rant about the inspectors.
Great video. You showed us handymen important complex information in an easy to understand way. Thank you for sharing your knowledge!
Hey thanks for taking the time to do this. Awesome information!
The National Standard Plumbing Code used in New Jersey allows short pattern fittings to be used in horizontal to horizontal changes in direction. But only for individual fixtures.
Thank you! I am turning a washing machine drain into a shower drain and appreciate this info :)
I immediately subscribed to your channel because of the informative code and extra details in your video,
Thank you so much for your time and efforts sir,
God Bless.
Thank you very much for the information, just moved to a house with this problem, toilet so closeto a T that waste backs up!!! now I now how to solve the problem
I have been doing plumbing for 56 years, with the last 38 of those years working for myself in Australia as a licensed plumber, roof plumber, drainer, gas fitter and LPG installer
I have seen many changes in the industry, some not good but most were.
As an apprentice, I spent 5 years studying, 3 years to become a journeyman and 2 years of advanced plumbing to become licensed.
I began with earthenware drainage pipes joined with cement, copper for hot and cold water, with copper wastes into cast iron stacks in multistory buildings. Also galvanised steel pipes for gas lines.
Today, almost everything is in plastic.
The worst is that a plumber today is more interested in the money than the job.
Most of them think of a plumbing license as a license to print money.
Even though as I am approaching 72, I still work part time as a licensed plumber.
I like it too much to give up completely.
There is some differences with what we call the fittings.
For example; a sanitary 'T', we call an 88° square junction.
We don't have "a combo wye and 1/8 bend", we just add a 45° bend to a 45° junction.
We never use fractions to describe any fitting, only ever the degrees that it is, that reduces confusion.
Our sanitary bend fittings come in 5, 15, 30, 45, 60 and 88 degrees.
Kenneth Lyneham mi
Wouldn't the only 88 degree fitting be a sanitary tee?
Marti a....your comments and attitude is exactly why there are very few goog tradesman any more. They take it on for money and not a lifetime vocation. I'm a carpenter joiner and will never retire from learning more about my trade. More power to the dude still on the tools at 72. You see i know where he's coming from.😀😎
Martin Allen The man enjoys what he does.When you love what you do it isn't work.

Can you make more videos please? I'm an apprentice plumber and your videos are the best I can find.
I'm remodeling a bathroom and find this video to be of great help. Thanks for posting.
Thank you for this easy to follow advice !!
I swear our computers are listening in on us, only last night my neighbours emptying of her bath tub resulted in much gargling in my bath waste. Her dad is a plumber! and ever since he made an alteration in her bathroom my bath drain is noisier, To cut along story short, it woke me up, the computer must have heard my rantings and low and behold just the following day the 'potential' answer, come source of my troubles is most likely in this video. Thank you for posting, so nice to hear from people with a really professional outlook and conduct. I do a bit of plumbing myself sometimes so I am without doubt taking on board what you have said.
Watching this as I'm driving back with the sanitary tee to do the job. I guess I'll turn around and take you back. Thanks for clarifying
Thanks Dylan! I could have saved myself a failed rough-in drain plumbing inspection had I seen this video first. :) I just received your free PDF download cheat sheet for this. Thanks! I got the impression it was going to be more than what you showed on the screen during the video, but I like it and saved it for future reference nonetheless! Looking forward to more videos! :)
Thanks Tom!
This is great info and it’s nice to have a short to the point presentation but it leaves a lot of questions unanswered. Does this formation also apply to ABS? Does this formation apply to only certain diameter pipe?
I am an apprentice but Ive ran into this a lot surprisingly, Im glad my boss taught me up on the subject
Exactly what I found under my house that’s clogged🤦♂️ Great video-answered every question in minutes!
Thank u for the video u made it very simple to figure out what to use in this application
You Sir are the Best at Plumbing Knowledge & a Life Saver for providing your Amazing guides to you're viewers.
I have Liked, Subscribed & now commented on you're video
..this is the least I can do, to show my appreciation for you're work...thank you!
Thanks!
Gr8 vid … Thx for your time, effort and energy in putting together this concise informational video. Kudos.
Cheers,
Thanks for sharing this. Great information. As a plumber for 35 years, I tell inspectors all the time to call me if this line backs up so I can watch a maintenance man pull a ceiling cleanout plug for a stoppage on floor above. He responds and said "It's the code" and I say "don't forget to call me!" Lol
I don't get it. Obviously you have to be a plumber. Something is code but stupid nonetheless?
Lisa O'Donnell oh indeed it is! In TH-cam now watching music vids, saw your notification! Lol I'll send you a video of why ceiling clean outs shouldn't be used.
Can't find video of apprentice pulling plug from cleanout on floor below stoppage but it's classic.
Why would anyone pull a main line clean out plug inside of a building. I've been in the business for well over 40 years. I'm not sure I've ever pulled an inside clean out. Go outside and open the outside clean out. Run the snake back towards the building. 99% of the time mains do not plug inside a building anyways. The weight of the water will push anything you can put down a toilet clear out of the building. What stops up then. Is roots, broken pipes, pipes don't plug unless the waste has something to hang up on.
Great job. You have a really good voice for narration. Very clear and articulate.
Thanks Peter!
No matter when you recorded this video; it will always be relative as long as there is “PLUMBING “!
I Am going to use this info.
Now!
Thanks Dylan! Big up to you sharing when the people!!!!🌺💚🔥
As a drain tech I thank you for this, I hope an installer learns from this. One other thing that is code that I wish wasn't is the use of double wyes. A sewer cable has a very difficult time with making the turn. It almost always goes straight across unless there is a length of pipe between the wye and 45. Usually they are put in with street 45s into the wye or are part of the fitting itself. I have watched on camera cables going right across these fittings. I have also watched waste getting deposited up into the opposing branch after a toilet flush. The waste is pushed up and is left there as the water drains out. If the branch that is receiving this waste doesn't get used much it will eventually become clogged from the other branch line. This was a serious head scratcher for us until we actually witnessed in on video.
You actually gave a really cool explanation. Thank you.
Perhaps you should start a TH-cam site showing your camera views of such issues as you come across them. Maybe you will be the next TH-cam Star.
Very well explained on waste vent piping and sweeps..Thank you
Henry, I'm glad you enjoyed it. I try to make these tutorials short and sweet!
Not talking about venting! Talking about moving shit!! And shit don't move in a vent,! Just air
Thanks for the free guide brother! God Bless!
Thanks!
This was very helpful and thanks for the information
Useful information. In short, when in doubt, use the largest radius bend that you can fit in the available space.
Amen Hammerpedia! I've been cleaning drains & sewers for over 30 years. You are dead on. Nothing more frustrating than a tee when there should be a combo or wye.
I recently cleared a bathtub line where the homeowner did his own plumbing. He said he couldn't get the trap to line up with the tub drain, so he built a "360 degree loop" followed by a p-trap. My stomach sank. This was in the basement with a concrete floor.
Getting a 1/4" cable through it was hell, but with lots of persistence I got the cable through and into the main sewer. The water drained great. There was just one problem.........I opened the back flow prevention device (it was about 5 feet away) and I saw the cable in there. Problem was, there was no water coming through. Hmmm. That means the pipe broke under the concrete.
Sorry mister homeowner, but if you don't know how to plumb, this can be the result.
Last I knew, he was jack hammering his basement floor.
Thanks for the video.
The item you are referring to is a Backwater Valve for drains.
A Backflow Preventer is for potable water.
I don't always turn 90, but when I do I use a long sweep! Keep it long my friends!
Hello Dylan, My question is, Is it allowable to drain a toilet toward the front and have venting coming from behind?
I wish I could do videos like this. I save your videos to show Construction apprentices that get assigned to my big jobs.
This is why I always call a pro for larger projects
Hi, must vent pipe be vertically straight to the roof? Can it be like an upside-down L shape going out through wall?
I installed a new bathroom, but i dont want to open another hole on the roof. Can the vent pipe go out through the wall instead? Thanks
In San Diego we just shit in the streets. Toilets are for the millionaires.
Cfass1 in Michigan we shit in the woods.
Heck with 90's use all wye and 1/8 bends with a fitting clean out on back when there's room in your own home the future accessibility is great
Hi sir Dylan. Thank you very much! your videos helps me a lot to do my job right hence I am fixing my own house plumbing.
Virgillo, you are welcome. Best of luck on your plumbing project!
Hi Dylan. I am going to Austin for my test for tradesman. I am nervous. What do you recommend? Do you think ill pass?
Thanks for all this great info
Thank you for the very valuable information.
Old Builder here (72) and it makes me chuckle to see how many "master plumbers/inspectors/pros...." comment here after watching! :-) You figure they wouldn't need to be watching any of this on YT, right? haaaaa.... Me...I just like pretty pictures :-) Thanks for the show!!
Anyone running DWV, should have these basics in the forefront of their minds when slinging pipe
This is for directional flow having to do with drain cleaning. I believe it’s still code in my area to use a double wye but if it were up to a lot of local plumbers they would make them illegal to use , either above or below ground.
I purchased the course and it is excellent.
Thanks Roy!
Is it possible to plumb a whole house interior with schedule 80 (gray pipe) with all the various bends?!?! I saw a video of a high end home being built and they said it was being done there as more of a sound deadening material but I hadn’t heard of it before.... Thanks
Very cool of you to prepare a video on this. Thank you!
You bet!
Do I need a vent or wet wall directly behind the closet flange? And can I tie in a shower drain to that same line and if so do I need a separate vent? Thank you
Thank you for such helpful in depth info
Thank you so much, I need this information!!
Incredibly knowlegeble video.
Many Thanks!
I am installing 3 salon backwash shampoo bowls side by side and need to create a simple drain chain for all of them to flow into one pipe. Do you have a product that I can buy that addresses the best way to do this to code? Thanks in advance!
Very cool short, informative vid. Ty!
Thank you. I have a house infrastructure is coming up the road and I want to be ready to connect. Anyone please let me know about where i need to be with depth in relation to public works. Thank you.
do you ever use different fittings for different contents, like smaller radius for just liquid? and long radius for solids
The proper "drainage" fitting is based on what direction the drain pipe changes (not what's inside it). Good Question 🪠
Thank you man !!!
Thanks Hammerpedia, legend
Hydroponicist here and I found this very enlightening but not usually what I do with PVC pipes.
Glad I found your channel.
I have a 12 square meter roof and i want to affix a rain floor drain with a downwards pipe. What is the smallest ammount of tickness. Can it be less than 7 cms? Thanks.
Great info, many thanks!
Thank you so much. Amazing video
Hi just want to ask what is the free software to design pipe with collection of multiple pipe fitting, so i just need drag and drop to design the pipe flow
If I use a combination wye can I add a 45 directly to the end of sweep? Almost a 180 turn. It will be stubbing out at the far right side of my sink cabinet and I would need to turn it back towards the sink a little.
Trick I learned from a Australian plumber years ago. Have to install a toe tap tub waste on a slab? With plastic tee,boot and overflow? Lay a piece of plywood on the floor and tack a piece on the studs. Use a pencil to mark the plywood through the holes. Then, pull aside the tub, make your measurements, using your marks. You'll never have a boot too low or too high. Same with the overflow.
If I have a 50 ft run with a four inch sewer pipe, from point A to point B in a straight line, is it still a quarter inch drop per foot? = 12.5 inches?
I really appreciate this. Thank you
Most of the problems are back flow and or sucking the P trap dry. I agree with your video. However I would do a back up video of why these codes exist. To explain proper venting, back flow or P trap safety. Such as keeping out sewer gas and the reason these codes exist to prevent future problems, or dangers of not having proper flow, vrs suction. Good video by the way. I believe the more people understand why these codes exist, the more likely they will follow the codes. ;)
Great points Chris.
Or if you want to do the plumbing...go get trained properly maybe? Stop relying on the professionals to make free videos on how to.
Dan Bedard
He clearly stated in the video that even professionals are guilty of making this mistake. It helps to have some cursory knowledge of these things so you can potentially spot an error that is being done on your house. It also could keep the help honest and in top form if they know the person understand the basics
Dan Bedard You've been making this mistake, that's why you came here to get educated! LMAO
Or they can just follow this or do ur 5 year apprenticeship like most do
I am plambar in India . You. Are knowledge is very good.
So what issue would this cause? I have this and the straight run “not coming in through the sanitary t” is backing up but I’ve cleared it with an auger and checked for vents being blocked and nothing. Will drain if after a few days and gurgles the whole time when it’s drained enough to do laundry. The toilet that comes in of the sanitary t has worked fine the whole time so not down the line it’s just the straight branch off the t.
Would this be the same for a drain to a leach field? I notice people are using the sanitary tee to save money instead of a distribution box
Great video thanks. Very helpful!
As a Master Plumber & Gas Furnace Installer in Scotland, I 100% approve of this video. It's the same over here.
;)
Question!
How mani times did you do it before someone told how to do it
Can I connect two long sweeps (sink drain) to go round an immoveable object?
Thank you very much
Highly precious material, in most condensed, best-presented format.
Congratulation to put such great content in such a short and valuable clip.
All, please value and do the least, LIKE this clip and subscribe.
Waooooo super cool video!!!
And very simple to understand 👏👍
My city follows CPC (California Plumbing Codes). So is this the same as IPC or UPC or an entirely different animal of itself? If later, where can I find a reviewable copy of it online?
Thanks
Do u have waterline installations videos?..God bless u!
Thanks! I was able to use this information when I plumbed my brother's bathroom. I put up a video to show how I was able to DIY with confidence now that I know how NOT to do it.
how do you get hold of one of those code books for S.C ?
Great video, what is the software you are using to show this?
Thank you, we use sketchup
Thank you sir.Thumbs up for your videos..👍God bless.
Excellent information! You sound so much like Owen Wilson. I love it.
Glad you found it helpful.
basic stuff......
if you are watching this video to learn plumbing may i suggest buying the illustrated plumbing book. also attend a class about backflow. Find a plumber that has years of experience doing residential and commercial construction. Check with your local utility and see if thay have seminars on heating. Learn about controls regulation venting and venting.
when you do a toilet what is the rough in measurement for the pipe through the floor ??
Congratulations, I am soon retiring too,it's a journey that challenges you everyday, good luck.
I've worked in both UPC and IPC areas. I always preferred the UPC due to its higher standard (fewer allowances.)
Thank you very much for you sharing this important detail.... thumbs-up have a wonderful day....!
You are welcome Liberty Tires. Have a good one.
do you have a video on putting in two washers?
