- www.AsktheBuilder.com founder, Tim Carter, shows off some of the cast iron drain pipe in his daughter's new home. Cast iron drain pipe offers lots of benefits. It's fireproof, it's quiet, and you can't drive a nail through it for starters.

Had a house with lead drains...now that is a quiet pipe. My current 114 y/o house has cast stacks and copper vents, Sometimes newer is not always better. Thanks for your great info over the years Tim, you have saved me a bunch of $$$. Have used and loved Stain Solver for years!

All lead drains? I’ve never seen that. I’ve seen lead tub drains with drum traps or lead closet bends but I’ve never seen a whole system that’s lead. Then again I didn’t know lead water lines were a thing until recently
Direct and to the point, covering a variety of related topics thanks.
I really like how your building a new house with cast iron! I'm no plumber but I've always liked how the old houses were built and hate how cheap everything is made with plywood and plastic in newer homes.

Trust me they are not using any plywood in a new build
Thank you for the video and excellent information. I'm doing some remodeling in my home that's over 100 years old. I'm a big fan of quiet and currently do not hear even an iota of noise from my cast iron pipes. Many plumbers have insisted on replacing them with PVC. Nope!
They are extremely quiet. The ones in this video were installed in my daughter's home and you can't hear any water crashing down a vertical stack or running across a ceiling in a long branch arm.
Always fun to watch! Thanks for sharing

Hey Tim, I've been watching since 07. Thanks for still making videos. Would love to see a video on swaging copper pipes.
I'm not familiar with the term "swaging". Do you mean sweating or soldering? If so, I recorded that video about 20 years ago! It's on my channel. Try: soldering copper tim carter in the RUclips search engine.
@@askthebuilder swaging (according to Wikipedia) "is a forging process in which the dimensions of an item are altered using dies into which the item is forced." I've seen where plumbers will pound a die into the end of copper pipes to form a bell instead of using elbows or couplers.
Oh, I've done that countless times to create a flare in soft copper. Flare fittings are best for gas and permanent water-line connections underground. I've just never heard that word. TNX for sharing.
can u do a program on draining a slopping property especially if you place a house at the bottom of the slop I.E. Can you put a long pipe vertically underground across the whole lot to catch the water coming down under neath and direct the water to either side to sunlight? And/or what kind of drainage would you need under ground related to a slab foundation?
I've already done what you need. It's at my AsktheBuilder.com website. Go there and type this into my search engine: linear french drain I also offer a phone consult service if you need lots of help: shop.askthebuilder.com/products/15-Minute-Phone-Conversation-with-Tim.html
Cast is for commercial use and from my experiences DWV cast is much louder than Schedule 40 PVC. now I agree ABS DWV is loud but for residential cast is over kill especially if the home owner has to make a repair. Thanks for sharing another helpful video.
This video is trying to dispell that myth about cast iron only being for commercial. It's perfectly fine for residential. The issue is so many young plumbers have not used it they think PVC is the only material to use. Cast iron is not overkill for the drain lines. I agree that you can switch to PVC for all the vent lines to save money. TNX for the kind words.
Ask the Builder you’re a true professional. I’ve always respected your opinion on matters. Thank you for your rapid reply.
@@askthebuilder yes. Agreed. It's not like we're doing oakum and lead joints. These are Fernco couplers. The noise difference is quite literally this:
PVC is loud and can drive you crazy.
Cast is inaudible
The couplers are technically no-hub couplings. The Fernco coupler doesn't have the wide stainless-steel corrugated band, but instead two standard band clamps that fit in a slot at each end of the Fernco fitting. But no doubt the same idea!. The wide stainless band imparts lots of strength to the connection. It also keeps the pipes together in the event of a fire.
watch this video. You won't believe your ears haha ruclips.net/video/P3UHWGEhqSw/видео.html
I assumed they made 1 1/2 cast iron but I’ve never seen it. The supply houses we use don’t carry it. We do a lot of commercial and it’s mostly cast iron but the only time we use 1 1/2 is for stub outs or trap arms. When we do that we use dwv copper. We do use 2 x 1 1/2 tapped tees if the stub out comes straight out.
Yes, it's made and it's fun to work with! Be sure to use BlackJack!
Loved it!!
Im working on a waste crew i really want to succeed as a plumber love this work
Here in Chicago cast iron with lead and oakum is still used all over here. While I can see using cast iron for the main stack drain and toilet elbow drain, it seems unnecessary for the vents since they don't carry water.
Yes, you can use PVC for vent lines. I had plenty of cast iron so I used it for lots of the venting.
I have a lot of problems with a bathroom sink that clogs up yearly. The PVC from under the sink connects to a cast iron pipe that is in the wall. My guy says unlike PVC this pipe gets pitted over the years whereas PVC stays smooth. It's probably 50 years old.
I'm assuming nothing has changed in regards to the insides of this type of pipe pitting and holding onto stuff?
Modern cast iron pipe is not like the cast iron of old. It has a much smoother inner surface because it is spun cast, not poured into a mold. What's more, the only way your *guy* can tell you what the inside of your pipe looks like is to send a camera down inside it. This is easy to do by removing the toilet. Your bathroom sink clog can be from a galvanized iron branch arm that has become choked off. Watch the *second* video on this page where you see a smaller pipe sitting on the top edge of a dumpster: www.askthebuilder.com/pvc-pipe-vs-cast-iron-pipe/
Here in Orlando, FL there is a law firm that is looking for homeowners with old cast iron drain pipes (I believe built before 1975) for a class action suit. They claim the pipes are disintegrating.
I wish I could get on that jury trial! It's complete BS. The pipes that are failing are no doubt in the ground in warm brackish or salt water. Any average person who paid attention in high school chemistry class would know that steel and iron in warm saltwater is a recipe for disaster.
All one has to do is go to an Orlando hospital that's been around for 40 or 50 years and ask them if they have any failing cast iron pipe in the walls and ceilings above ground. I already know the answer: NO.
For goodness sakes, it's not REASONABLE to expect the cast iron to last in that kind of environment. Anything made of steel or iron rusts rapidly in Florida. I'm so sick of everyone trying to place the blame on someone else. Those with failing pipes should be going after the builder or plumber for not using common sense, not the manufacturer of the product. And building owners should be more active in selecting materials and employ their own common sense.
Thank you sir!

Hmm, interesting to hear the other side of things. I was just about to replace my rotting cast iron from 1957 with PVC. Might have changed my mind. No walls near mine, so nails aren't an issue, and noise is not a big issue since they're in the basement, but I'm intrigued nonetheless.
I would run pvc under ground and convert to cast iron once it comes through the slab.
I put all cast iron in my daughter's new home. It will last 100, or more, years. NO NOISE when water flows across the ceiling or down the walls.
Glad to see your using cast iron but why not do it right and pack and pour the joints?
Hmmmmm. Who said it's the *right* way to use oakum and lead????? Is that the latest advice from Charlotte Pipe? Can you paste in the URL to the PDF that says that method is better than the no-hub couplings?
these fernco couplings are for remodeling and repair only .not supposed to be used in new construction, you should join the cast iron with lead and oakum. is your local code allow these connection in new construction ?
I've done lead and oakum and feel the no-hub cast iron with the no-hub couplings is a much better and faster way to connect the pipe to fittings. Have you not used no-hub yet? If so, you should try it. GL as we say in Morse.
I used no-hub couplings to repaire the damage CI that rusted and cracked due to the outage and connected to PVC DWV . but you didn't answer my question about using these coupling in new construction?
The plumbing inspector in the town I'm in allows the no-hub couplings you see in the video. I'd never use anything else. GL.
@@progressplumbing5203 Legal just about everywhere. These are not repair couplings. Those are shielded No-Hub couplings that meet CISPI 310 ASTM 1277.
I work in office buildings. Most everything is cast . If I could show you all the pipe I've taken out it would deter anyone from getting cast. The cast pipe pits, corrodes, clogs, deteriorates. If I could snap my fingers and have it all changed to PVC or abs, I would. But the fire rating is the issue. Now, if they made cast iron pipe sleeved with PVC, that would be something
How old are the buildings you're working in? Are you removing old *true cast* pipe or modern *spun cast* pipes with no seams? Clogs are endemic with most pipes and worse with galvanized iron branch arms in older buildings.
Yea well that's the reason we index everything dry first prior to cementing the PVC . exactly so we don't have fitment issues ..but if you want to spend the extra for cast iron drainage than that's entirely up to you .. We had a PizzaHut owner who called because he had foul odor's all throughout his restaurant but when I used my scope to see what the issue was I learned after year's of using highly caustic cleaner's in his Drainage plumbing and NOT flushing them out well enough he had eaten an almost 2 inch gap all down the bottom sections of all his drain pipes so his entire plumbing had to be dug up which was extremely expensive and replaced with PVC ...
The same thing can happen with PVC is you put chemicals down in that eat away at the plastic. The Pizza Hut owner is to blame for the failure because he didn't use the product properly. The best analogy I can muster at this time is saying a truck engine sucks because the owner decided to put some crazy liquid down the oil-filler tube. You can't fix stupid is what I'm coming to believe.
Do you have a video showing where that goes in the basement and how it goes into the septic tank?
I have other plumbing videos and ones about septic tanks. I've been a master plumber since 1989. Do you need HELP with something? Do you want to avoid a COSTLY mistake? Consider this service I offer: shop.askthebuilder.com/15-minute-phone-or-video-conversation-with-tim/
@@askthebuilder just trying to figure out how that pipe fits up to septic tank and stuff like that

@@askthebuilder do you have a video of how it all works or no
condos in Toronto use cast iron for sanitary and vent lines.
My guess would be it's a fire-code requirement for multi-family buildings.
Great vid,,, but we have cast iron in our 1960's home and I hear when the tub drains or the water coming down when we flush the toilet.
Are you sure you're not confusing the sound of the water running in the water supply pipes to the sound of the water draining down the waste pipe? Some water supply lines are very loud.
@@askthebuilder No, it probably sounds just like All in the Family.
Yes, at least have the in a two story home have the main sewer line that comes down cast iron. We have some friends that have a home built and it’s a beautiful two-story home but every time someone flushes the toilet all you do is hear water rushing down the inside of the walls
Like All in the Family?

did anyone notice the Wye. Is it suppose to be like that?
Where is the wye? What time in the video? Everything you see in the first minute or so are tees. With cast iron, the tees have a generous sweep.
1:02. Why is the WYE upside down.
are both the pipes going to a vent? 1:02. I guess that would be okay right if it was for venting not draining
@@sh2697 Let's engage our critical-thinking skills, shall we? What is moving through the pipe at that location? Which direction is it headed?
@@sh2697 Yes the straight pipe from the floor up to the ceiling is the vent for the toilet on the other side of the wall. The upside-down tee that aims to the left is the vent connection for the scullery sink I showed just a few seconds before.
1:08 isn't that sanitary T upside down? Wouldn't that obstruct the gravity flow of the water or is that just for venting?
It is upside down. That's the way you install them for vents. Think about the way air is flowing down from the roof into the system. I encourage you to watch this other video of mine so you have a clear understanding of the direction of air flow in vent pipes. Most people get it wrong. ruclips.net/video/WBU76ZcrGlM/видео.html
It's a air vent
Why are you using cast iron pipe..? Is it code in your area.
That's a great question. The answer is here: www.askthebuilder.com/search-results/?q=cast%20iron%20pipe
I agree that cast iron is the best product. However just recently an apartment that I own all the cast iron is splitting. I am forced now to replace with ABS plastic. The cast iron was made in the USA and perhaps had only a 40-year life. I know of homes in the area that are over 100 years old and they have never replaced their cast iron pipes. I assume the companies that made the good stuff in California are now in Texas. The people that made the cheap stuff sold out I am sure.
You should reach out to the Cast Iron Institute and see what they say. www.cispi.org/
Finally heard someone mention quietness for cast. If Its for my house or kids, its cast. I care about their ability to survive a fire, should it happen. Commercially cast is code, residential, they're not so concerned because of a limited amount of fatalities. Most die from poisonous fumes, not so much the fire itself. If you were in the military and experienced the gas chamber, you'd know what I mean. I lived in an apartment in 1985 and the landlord on the first floor prohibited showering or flushing any toilets after 10PM. They replaced their cast with PVC,.... big mistake. what a racket.
It's SO QUIET. I put it in my daughter's home - this video - and you hear NO WATER rushing across ceilings or down walls. To get unlimited tips each week, subscribe to my FREE newsletter at www.AsktheBuilder.com
Every cast iron drain I’ve ever had has had problems and the problems cost thousands, PVC and ABS is a ton cheaper, easier to install and you can fix a small section fast. Cast iron is great for plumbers, not so great for home owners
I can fix a small section of cast iron installed with no-hub connectors too. Modern spun-cast cast iron is so much better than old true *cast* iron. Try to expand your tiny gray cells and realize that improvements can be made with products.
Cast has advantages ,one draw back it will not flow as well as PVC ie carry waste away .
Billy, can you provide the independent scientific study that backs up your speculation about water flow through different pipes?
the key flaw in your argument is. CORROSION. in maybe 50-50 years depending on usage, that cast iron will be the same diam outside. and the inside diameter will be around the size of a marble. cast iron pipes rust out, cause leaks, are a pain to install and remove, vs pvc. you can gut, cut, glue. easily add or remove sections. its cheaper. and you dont have to thread parts in or depend on rubber connectors.
seems a small price to pay if you need to find a competent carpenter that doesnt have a habbit of shooting nails into plumbing.
The key flaw in your comment is, and I hate to say this, the lack of critical thinking. If cast iron was such an inferior product why is it one of the most specified *DWV materials allowed in large commercial and institutional buildings?* Do you think for a moment building owners of multi-million-dollar facilities would be okay with replacing plumbing pipes every few decades? Do other RUclipsrs a favor and *stop leaving comments where you have no expertise* in the topic. Go research all of the plumbing and building construction trade publications and come back here with a list of URLS of past articles from those sources that support your claims.
place all your bands in the same direction so you can get to all the bands .
By default you should be able to get to the bands at any point until the walls get covered. If you want FREE unlimited tips like this each week, subscribe to my newsletter at www.AsktheBuilder.com
Hmm... Something seems very wrong with putting a rubber seal behind drywall. Rubber seals usually have an estimated life of around 5 years.
Travis, can you please copy the URL to the independent study supporting your 5-year-useful-life claim in your next reply? Are you aware that no-hub cast iron is code approved for institutional use? I'm talking about hospitals and large commercial buildings that might be in service 100 years? Do yourself a favor in the future and don't comment on things where you have no real experience or background. You make yourself look foolish.
@@askthebuilder Wow. Way to lose a viewer. I was looking for an explanation as to how this rubber seal can last far longer than an ordinary rubber seal. If you'd rather insult me then fine. I'll go elsewhere for plumbing wisdom
@@travis1240 Wow! Perhaps you should re-read what you originally typed. Here it is: "Rubber seals usually have an estimated life of around 5 years." I simply asked you to back up that statement with independent proof. As always happens with folks like you, you *fail to provide the proof* and then try to turn the tables back on me painting me as the bad guy. Nope, not going to happen. The fruit rollups and juice boxes are over on the shelf by the coloring books.
You do realize your comments, and those of others, are here forever. It's MY JOB to cull through them and point out when folks like you provide WRONG information. I have the choice of just DELETING comments like yours, but I choose to use them as teaching moments for EVERYONE, including you. I suggested to you that you stop making comments about stuff you don't know about to stop littering the Internet with bad information. But you, like many, don't like to be called out in a public forum.
For the love of God, use your critical-thinking skills and think about how cast iron is used in commercial and institutional work where building owners CAN'T afford problems. As for you cutting yourself off from great information, life is full of decisions. Make good ones.

Cast iron pipes would probably make nice spud guns, if it were not so heavy ( word be hard to move that without assistance). LOL
Just make the spud gun with PVC but be darn sure you use the right one. Do NOT use the foam core PVC. We use these guns to get amateur radio antenna halyards up into trees. www.W3ATB.com
I thought the 1950's were over. I'm so glad I ripped out the old cast iron drain pipes on my home and replaced with ABS.
Did you purchase a pair of great earplugs with that ABS? :-O ;-)
Done the same thing!
Cast iron clog and build residue. They are very hard to work with and therefore expensive to install. I’m also glad I removed old heavy cast iron pieces at my house. If you want to make PVC quiet, just insulate the vertical lines. That also prevents from sweating and condensation.
pvc is not allowed in commercial buildings because it is flammable, cast iron is pretty much still relevant today
@@MrPopierdolka insulating them actually makes them louder. Dont believe me look it up there is a you tube of it.
Did Archie and Edith Bunker have cast iron in their house? Seems we heard the toilet a lot on All in the Family!
Go here on RUclips and hunt for videos that show what's done in post production when creating video. :-/
@@askthebuilder Well, bathroom noise was an issue with the original Star Trek. ST was filmed in 2 Paramount sound studios, one for the bridge and other interior scenes and one for planet settings. Nearby was a set of rest rooms. Sometimes people would use the rest rooms while a scene was being filmed and it would have to be done over again because somebody flushed and the water running could be heard. They had to keep people out of the bathrooms while filming. Since Star Trek was made 1966-9 and a sound stage is a commercial building, there was cast iron plumbing. This is from the book The Making of Star Trek.
Oh, and I think I heard a flush on Leave it to Beaver, back then the Cleavers definitely had cast iron. I don't remember hearing it on the Brady Bunch, but it would have happened because I think they had PVC by then.

Cast iron and some steel framing all around the house would been best 😝
You can buy straight lumber. Steel is tougher to work with and requires all sorts of other detailing that adds to the overall cost.
Sorry but the wye is upside down.Reversing this will let waste flow down and "suck" the air from the vent stack.You don't want to impede the waste and this arrangement will do just that.
You should probably not comment on videos where you're not knowledgable. That's a tee fitting and it's a VENT pipe, not a stack. Which way is the air FLOWING in this vent when the fixture drains a full sink of water? I've been a master plumber since 1981.
Looks like the fitting is upside down in the thumbnail
It's not upside down. Think about what's moving through the pipe and WHAT direction it is moving.
I want to use against mice under a cabin with pier and beam maybe.
That's an excellent use of cast iron. It's absolutely mice-proof. Mice can successfully chew through PVC or ABS plastic.

Homeowners don’t like plastic but also don’t like soffits. Well, it’s one or the other. PVC will fit in tighter areas, cast iron don’t !!
Can you point me to the survey results supporting your claim that homeowners don't like soffits and plastic? You should be very careful about making statements that you can't back up.
I came across two clients that wanted cast iron because they were convinced it’s gonna reduce the noise of water flow. They couldn’t understand why paying much more for materials and installation, the pipes still couldn’t be hidden into the ceiling. Ended up lowering entire ceiling by few inches because they didn’t want soffits. I support my statement by experience and I’m sure there are many plumbers out there that experienced the same issues.
I still like your videos, they’re very educational ! Thanks for making them :)
Thanks for the insight into your original comment. You could have avoided all of this if you had *originally* said, "TWO homeowners that I worked for didn't like......" I challenged you because your original statement could only be supported by a large-scale survey of thousands of homeowners that represent a statistically relevant sampling. I knew you would never invest in such a study. I just ask in the future you be very clear when commenting to help *everyone*.

Uh yeah untill 30 years later and the pipes corroded and everything clogs it up
I've been a master plumber since age 29. I was trained in the mid-1970s. I worked in OLD homes built in the late 1800s and early 1900s. The cast iron stacks in many were in excellent shape. That's far longer than the 30 years you casually mention.
What's more, *MODERN spun-cast cast iron* is made so much better than the old pipes cast in molds. The wall thickness in modern cast iron is uniform and very thick.
Let's talk about clogs. Any pipe material will clog. You'd do well to stop making comments about topics you have little, or no, background or authority. Please stop commenting on my videos or I'll end up blocking you. I don't want your misinformation out there.
My home is over 100 years old and has cast iron pipes. No issues yet. I'd say that's a hell of a lifespan.
That t is upside-down water falling down get diverted to the left
Time for a spoonful of tough love. It's obvious you're not a plumber. Or if you are, you need to go back to school. That's a VENT pipe connection. What is moving through that tee???? What direction is it moving? Do yourself a HUGE favor in the future and resist commenting about things that push the envelope of your tiny gray cells.
Cast iron rusts
Indeed it can rust. But if you install high-quality cast iron pipe as King Louis XIV did back in 1675 to bring water to his fountains at Versailles, you'll have no issues. Those pipes are still in service today. That's 350 years of service. Not bad.
