How to Fix Leaking Cast Iron Pipe

[@aletheajohnson6545]

Your video demonstration is straightforward and clear. The comments provided additional information for consideration. I am in a position where I HAVE to do the repair myself because no professional is available for weeks. You’ve saved me hours by demonstrating how to do this.

[@thehomefixer176]

I hope you can fix it, let me know how it comes out.

[@biliff1]

Probably saved you a lot of money for a plumber too!

[@aletheajohnson6545]

I just saw this thread. It came out great! Passed building inspector review and my plumber was impressed. Yes. It saved me a lot of money, too. Thanks, again.

[@mottle_]

Thank you for this. Not only did you show how it's done, you inspired me to do it myself and it worked like a charm.

[@thehomefixer176]

Awsome did you take any video of it?

[@mottle_]

unfortunately not, but i had to use your method of stretching the rubber ring because my plumbing is old. saved me a whole lot of stress and an unnecessary trip to the hardware store

Hello Home Fixer. I think you did a good job on a very difficult project. You made it work. I am working on a house built in 1953 for Air Force personnel to live in. Currently working on a toilet that has that 3 1/2 inch pipe. Can't find a 3 1/2 inch replacement flange. Lowes and Home Depot laugh at me thinking I don't know how to read a ruler. I did learn a lot from the video and from the comments. Thank you for posting.

[@thehomefixer176]

Use the smaller coupler and use the wood like I did to stretch it on there. It should work!

[@citrinwarren6073]

My pipe shows it ready to give up. This was frightening. Through your video I am ready to tackle the task with confidence. Thanks.

[@thehomefixer176]

What's your pipe showing signs of leaks? And heck yea Do it yourself, Save the money!

[@PCB1153]

First of all, great job !! and THANK YOU for showing us how to do this repair. I just saw your video and am heading to Lowes to buy the tools, the PVC pipe, the rubber connectors, etc., to attempt something similar in my home.

[@thehomefixer176]

Its really not to hard at all, let me know if you need any help or advice.

[@frankvigilante3423]

Not bad u got it done.I would have put that clean out on the vertical but it will work

[@curiouscat3384]

Thank you for the encouragement. I'm a 70 yr old lady, am renovating my 1920's house and need to replace the old sewer vent. I've planned and prepared but wasn't sure if the Diablo blade would really do the job without a lot of muscle power. I'm more confident now and will get this project finished! Question though: wouldn't a heat gun on the rubber coupling be easier to stretch it?

[@thehomefixer176]

Heat gun may have worked. But the wood worked great for me.

[@radiantonion8615]

JB weld can fix holes as well but cast iron can still rust, but it could help if it's a relatively easy job or you don't want to do a ton of stuff to get the job done.

[@rogermccaslin5963]

Cast lifespan is 40-50 years. Beyond that is borrowed time. If I was doing all that work I'd replace everything I possibly could, vent stacks included. Also, you can soak a fernco in hot water and the rubber will become very pliable. You should also put shear bands on the fernco. They will keep the pipes aligned in the future. If not, the joints can become misaligned and cause clogs.

[@donschafer3428]

Soaking the fernco in hot water is a great idea, thanks for posting!

[@azmrblack]

I know many people have patched them with epoxy fiberglass-type patches, but it's better just to take it out and redo it anyways - homes that still have the cast iron that stuff has been in service for the last 50-100 years - and it's been rusting from the inside out all that time, so most cast iron DWV is probably at the end of it's life or past it. I found it strange that your horizontal runs are sitting on the basement floor, do they have the correct fall/pitch?

[@thehomefixer176]

Yes it pitches down into the dirt and under the concrete slab towards the main clay sewer pipe. Yea Clay sewer pipe which is probably older than the cast iron.

[@booglog]

when i saw the title i was thinking i was about to see some sort of micky mouse spot repair on cast iron, glad to see you actually replaced it lol

[@thehomefixer176]

I did think about putting a bandaid on it, glad I didnt go the easy route cause those do not last.

[@djbengi74]

Nice job you made it work for you nothing wrong with what you did I do this work every day . I don’t curl with the pipes I cry every time I have to move them getting old sucks

[@thehomefixer176]

Only problem is the cast pipe started leaking again higher in the wall, so I got to gut the walls now inside to get to it!

[@matthewsidener6905]

If you did this everyday you’d know you’re not supposed to go from 4” to 3”. You just created a bottleneck

[@thehomefixer176]

@@matthewsidener6905 Its ok the bottneck is only 12 inches from the clean out. So if it ever does clog it will be easy to service by me.

[@franksprecisionguesswork501]

I would have tried to finagle a tee into the wall where you put the back to back elbows. That way your clean out would be accessible from the outside and at a much higher level.

[@abrahamvaro5482]

Super very nice video ,thanks!!!

[@kiwiswat]

You cant use that fernco above ground. All rubber ones are below ground. You have to use banded coupling. Basically it is a full steel jacket

[@thehomefixer176]

Cant, yet I done did it without issues.

[@kiwiswat]

@THE HOME FIXER ability to do something does not make it right. There are many people who splice wires in the wall without a box. They can, but that's a fire risk. Rubber fernco is not approved for above ground. Shirlded coupling provides strength for the connection and prevents shifting and movement, which can cause a leak, especially with cast iron connections.

[@thehomefixer176]

@@kiwiswat Only reason they want the shield over them is for Vermens not to chew through it so it is such a small risk of that happening.

[@thehomefixer176]

And if your are afraid of that wrap the rubber fernco with some aluminum sheet metal, roofing flashing would work.

[@juanespinosa3229]

One other thing you could have done to test your PVC pipe is to get a test balloon and fill your pipe up. To make sure there is no leaks You put the test balloon in your test tea

[@realfire6883]

I have the same problem from my upstairs bathroom. Ok when the shower runs but if you flush the toilet when the shower is going it leaks big time into my ceiling downstairs. crack must be on the side or top of the cast iron. Ripping the ceiling out tomorrow it can't handle excess water flow

you have 4 inch going into 3 inch which can create clogs.

Yes so I have been told. Im not worried about it as the bottle neck is less than 12 inches from the cleanout. This cast iron has been 4 inches to 3 inch for almost 100 years in this home. If I ever have to redo the cast iron that's left under the dirt I will put in 4 inch up to the Clay sewer pipe T.

Do you have anything at the bottom of that vertical pipe run to hold it up? That cast iron pipe must be awfully heavy.

[@thehomefixer176]

It was held up by the toilet flange cast iron 90 which was secure. Had about 11 ft hanging down from the toilet 90, it was secure tho. That upper pipe later was leaking as well, so I had to redo more of the pipe higher up all the way to the toilet flange area 90 elbow.

[@bobbys2160]

isnt the 90 at the bottom suppose to be a long sweep 90 into the horizontal pipe

[@thehomefixer176]

Not sure depends on code in your area. My old cast pipe had short 90 on it. I think it's what I used, although yes I could of gone with a long 90, but the cleanout is less than a foot away from it so it really doesn't matter in my setup. If No clean out then use a long sweep 90 Id say!

[@thehomefixer176]

I rewatched my video, at 11:28 I did note I was using a long 90 at the bottom. So Im glad i did originally in the beginning of the video I was going to use a short 90.

[@ElderAEShelton]

Won't the petroleum in the Vaseline degrade the rubber fittings?

[@thehomefixer176]

No sir, the rubber is derived from petroleum and natural gas (synthetic rubber). Because of its elasticity, resilience, and toughness, rubber is the basic constituent of the tires used in automotive vehicles, aircraft, and bicycles. So that said vaseline which is petroleum product it shouldnt hurt the rubber which is made of simular substance.

That's 3" cast iron, they make a 3" cast to plastic mission band that's thick on one side and thin on the other. You'll eventually have problems because you've now created a lip . When you have to redo it run 3" with the proper transition bands

[@thehomefixer176]

You mean its better to stick with the 3 inch PVC pipe and not use 4 inch? That way I use just a 3 inch to 3 inch band.

I'd also get as much as possible out before it exits the home

[@-ultravic661]

By stretchibg the couplings and installing them over smaller pipe, they are now under constant stress. Rubber dries-out over time. The vasoline is a petroleum product and it might weaken the rubber. Those rubber couplings might burst-open some day. If this does happen, at least they are easily accessible and fixable. This is just my guess. I'm not a plumber, but I am a genius. So there.

Man what ever, it worked for me and would work for anyone else who had 2 cents. Its thick rubber and stretching it a little won't hurt it as long as its not ripped. It saved me thousands from not hiring a clown plumber like you.

[@ShadyPlumber]

@@thehomefixer176 Mr. Sensitive. But, for people who want to know how to actually fix it, watch someone else. There are fittings that transition from cast iron to PVC. They are made of PVC and allow the use of a no hub coupling to connect the cast iron to the PVC without the use of wood to stretch out anything (why wood isn't sold at the plumbing supply house). The person making the video needs to learn how to take criticism, especially when he's making a how to video. I've been plumbing for longer than he's been alive and could be his father. Have a good one bud.

[@thehomefixer176]

@@ShadyPlumber Yea well funny you say you're a plumber for years, you know what the local plumbers told me to do, they told me to use electrical tape over the cast to make it bigger to fit the 4" inch fernco. Someone with years of experience didn't know this trick, would you rather I used a fernco to big and wrap electrical tape around and around the cast pipe so it would fit. And I did buy the special pipe to fit on cast, it still was too tight for what ever reason, maybe the house was built with pipe that normally was not used in homes plumbing. The house was built in the 1800s. All I know is I bought every fernco they had and they were either too big or too tight. This was the simple fix with no harm done to nobody. And I stand behind my fix and would recommend this to anyone with the same problem. Maybe they can also try heating up the fittings in HOT water and a lot of Lube. But the wood was just easier for me. Just because someone does something out of the ordinary don't make it wrong. Engineer's make up new things every day!

Did you go to a plumbing store? Or did you go to home depot type store? Plumbing store I go to would have it. Please don't tell me you're going from 4 to 3. It's okay to go to 3 to four, but never go 4 to 3.

I love home owners that do their own work. However 95% do it wrong. The other 5% have a family member or friend that is skilled to help. You needed a skilled helper. For the people who believe this job was done correctly, hire a professional! There are four problems with this job. Expertise is not cheap and doing a job over is not cheap either. You have to pay for it twice. I’m sorry that I have to break the news, but this job needs to be completely redone. By the way, the metal flakes that came out while you were cutting the pipe tells me you need to hire a plumber to repipe your cast iron all the way to the roof. Including the plumbing that goes to that new shower. Always redo cast and galvanized before remodeling a bathroom. It will save you a lot of money, otherwise you’ll have to tear out all your new work to replace or repair your plumbing. I’ll look for the video for when you redo this project with a professional. I hope you take this of what it is, constructive criticism. Especially when you are making videos for others.

[@thehomefixer176]

Good eye on the metal flakes. The pipe did turn out to be bad higher up after a few months, it was cracked really bad about 10 feet up. I did open the wall up and do it myself again but it didn't cost me much, maybe $100 for a pipe and ferncos. I replaced most of the pipe up to the toilet flange which was the only thing still good. All in all I disagree that I needed a plumber as if you don't get it the first time you can always go back and redo it which I did. Here's the second video on it. kzbin.info/www/bejne/Z36le3SAncuhias Thanks for the comment, even tho I disagree, A skilled helper is always great if you have one, I had to rely on youtube plumbing pros, which I watched for weeks before I learned to do this work myself.
