Did this same job yesterday. mine was very tight. I could not get it to fit until (1) I got the rubber donut hot with some hot water and (2) to the PVC in the freezer to shrink it slightly. Once it was hot and a little lube, it went in. Beveling the lip is must. Hope this helps someone else.
Thank God! Somebody finally using the proper connection (Fernco cast iron to pvc/abs Donut). GOOD JOB! Next time use a little dish soap as a lube; way easier!
Mark Schneider What if the cast iron is horizontal in the the ceiling joists, two story, will that fernco work ? From a tub ,shower ...pvc to cast iron ?
Six years after you uploaded this video and still helping DIYers. Thanks! I was surprised to see the hub under the house, thought I had only a section of cast iron to deal with. Now I know how to fix it.
J CaaM you are correct. In my experience, I have found that when installing a hose in a awkward area as when working in the automotive field, spraying a bit of silicone will make the hose slide easily into place, and then when the silicone dries it actually helps seal the hose in place. So I was wondering about the same effect when sliding the PVC pipe into the rubber sleeve
+patrick donegan Some areas of the country, like here in Ohio, pvc is preferred. I do know that abs solvent cements much easier with a single step. PVC requires a 3 step process - clean, prime, cement.
patrick donegan ABS has been recalled by nibco and other manufacturers in almost every U.S. state due to shrinkage. Just head down to your locally mobile home park and try to find an ABS joint without drip stains. It's just for sump pumps now. Good idea using recycled material, but too much shrinkage long term.
everyone and everything uses pvc here in charlotte. I didn't even know abs pipe existed until I saw a video on here of someone replacing it. I was like huh black pvc lol
Xion Temoc I use a little heat from a torch, you really don’t need to do this if you don’t want but if you do make sure you’re wearing a gas mask and have good ventilation. Anyways if you clean up around the top of the pipe and then take a medium small chisel “I used a 6” chisel” then with the chisel find a groove between the pipe and the lead coated sealant and gentle tap the chisel with a hammer to make the groove a little bigger and slowly work your way around the pipe but don’t rush it and go a little deeper each time you go around the pipe. Maybe you or someone else has another way to do it but I found this was the easiest method for me
Thank you. everyone keeps saying lube it. but when you think of lube you think of grease. which is not the best thing to use with rubber. never know what reactions it might have long term. best to just use plain old soap and water to be safe.
There is a special adapter called a "hub adapter" or a "cast-iron pipe adapter" that is made to use with the rubber Fernco gasket ("donut"). It goes on the end of the PVC pipe to make it easier to get the pipe properly seated down into the hub and Fernco gasket. (Also a little dish soap or silicone spray would help as several other people suggested!)
Very helpful video - thank you. I cannot find the gasket rubber that you are using. Can you give me a manufacturer and part number so that my local shop can order it for me. I went to four plumbing places and they don't have a gasket like that. I need exactly the size that you are using 4" iron hub to 3" plastic pipe. Thanks!
Service Weight (SV) refers to the thickness of the cast iron. Extra Heavy Weight (XH) is the other kind. They can be used on the horizontal, but the pipe should probably be well supported.
Greeting from 2021. Think I'm giving your method a try. Even the Fernco directions state to put donut on PVC and drive gasket into hub (What a Bear -and still an inch I can't get to seat. -thx
What you have is a service weight compression gasket. It will work, but Fernco makes a donut for that application. Soapy water helps and put a piece of wood on that pipe and smack it hard with a heavy sledge to drive it home.
Hey. Good Video! Question? Would it be alright to use a clear silicone for lubricant?I have a metal pipe that has a small hole in it going into the cast iron.I can get to it through the closet,but its kind of tight & thought using silicone would help slide it in easier.
@FoxRcng708 I had a hard time getting enough heat to the pipe as it was only a few inches out of the concrete floor, but eventually we got it broken up and peeled the lead out.
In Ontario Canada.....you can only use white PVC under the floor in the ground and under the cement floor...reason is that in case of fire the off gassing of the PVC is to toxic. ABS above the cement floor....all PVC under the floor.
+pauleastend2 not where we live. Abs is not allowed in any of the plumbing where we are only in trailer homes or mobile homes because its not permanent. Its against code. We are allowed to use pvc. With your thinking about the toxic qualities , what do you do with PEX which is plastic used for water? or other toxic things in the home when burned, like furniture and wire insulation etc.
I have a similar situation but the cast iron pipe I want to remove from the clay hub is cemented in. Can I safely use a cold chisel to chip the concrete away from around the cast iron pipe to remove it? Or am I likely to break the clay pipe hub?
luckimom3 what do you mean? The pvc pipe is smaller than the cast iron pipe and will go in without it being tight and that’s why you need the rubber seal
I usually use silicone spray lubricant, and sometimes a little silicone grease applied to the pipe end and the Fernco to help install these rubber Fernco couplings. As someone also mentioned, which I have used in a pinch, cheap liquid dish soap also works good as a lubricant.
You are supposed to debur the end of the fitting and put some silicin spray or greasy or even washing up liquid as a lubricant not hammer fittings.. Never seen a plumber hammering the plumbing unless he needs to break the old system
@@SK-yw5ih You have to watch a lot of high priced plumbers spread bad advice. Same with auto mechanics at 185 and hour they cost as much as brain surgeons.
Nice to see the lead come out all in one piece. Tackling the same job today. Thanks for the video!

Liquid soap is the best option. (Dish washing liquid). Put it on the pipe & around the rubber. Then twist left,right whilst pushing it in.
@@tonydalton6756 I tried that first but it was too tight. maybe the bell hub was tighter than most. Thanks for the suggestion

Very nice work. Very helpful video. THANK YOU!
Heat your gaskets with a space heater inside a box or with the cab heater in your vehicle
Or dunk it in some hot water

Very helpful. Thanks for the video
Would Vaseline help insert the pipe..?
Status update? Any leaks 9 years later? Any problems you had to address? If so, what were they? Obrigado and Gracias!
Little bit of silicone spray would have helped you out a lot .

Is there some reason you are using PVC rather than ABS?
+patrick donegan Some areas of the country, like here in Ohio, pvc is preferred. I do know that abs solvent cements much easier with a single step. PVC requires a 3 step process - clean, prime, cement.
you don't have to clean abs?

PVC is the code requirement where I life. We are no longer allowed to use ABS for interior drain pipes like this.
Use 4 in sda fitting with plumbing grease goes right in then connect to the fitting VERY easy.
Very good. Thank you
I have the same question as a couple other guys. How did you get the original cast iron pipe out of that hub?
Torch and flat head screwdriver piking on the lead until all gone. Melting lead and pulling out with the screwdriver.
@@MrEnergyFree Thank you!
How do u successfully break out cast and lead from hub?

Be careful with chisel, the hub can break very easy. Use a flat head screwdriver and a torch to melt the lead.
precision chiseling / prying, also can drill the lead out with smaller bit
Drill out the lead around the hub with a drill bit then use a flathead screwdriver 🪛 to scrap and pick it out.
Where did you purchase this rubber from, I live in London my name is Frank and can't find one anywhere? Thanks.
I USA you can buy it at any local plumber. There is always Amazon. Search for FERNCO P44U-305 Bushing. Thank for watching.
tell the tech at your plumbing supply that you are transitioning from cast iron to PVC they will know "Fernco is just a brand name
@@StONEMASON23 thanks.
A little mineral oil and you would be in.
I have found that liquid dish soap mixed with water makes a nice slippery lubricant to help slip pipes into the rubber boots and such.
Thank you!
Thank you. everyone keeps saying lube it. but when you think of lube you think of grease. which is not the best thing to use with rubber. never know what reactions it might have long term. best to just use plain old soap and water to be safe.
Soapy water or any soap will make it slide on very easy.
butter it up with "duck grease" it will go in smoother
then cook the duck 4 dinner ...chuckle

Beats cutting the hub off. Thanks 🚽 from NY.
I'm doing the same thing! The hub comes out of the floor and I need to make it pvc.
putting some liquid soap on the pvc would make it easier to fit in
Dont use a hammer. lub it and push it in by hand. rock it back and forth while putting pressure on it and it would have been together in a few seconds
joemama1151 I always put a 2x4 on top of the pvc pipe and use a rubber mallet and I’ve never had an issue
Next time try putting a little liquid soap around the PVC
Very helpful video - thank you.
I cannot find the gasket rubber that you are using.
Can you give me a manufacturer and part number so that my local shop can order it for me.
I went to four plumbing places and they don't have a gasket like that. I need exactly the size that you are using 4" iron hub to 3" plastic pipe.

I got the gasket from my local plumbing supply. Not sure aboutthe part number.
I am in Canada and HD does not sell it here. I had it ordered and paid four times what HD in the US charges
Amazon
Check with mission rubber
Thanks a lot my friend,you have saved me a lots of money and it’s the easiest and the cheapest way to go!
A helpful video! That rubber donut is called a 'service weight gasket'.
That name implies its held in place by gravity. Can these also be used in a horizontal connection?
Service Weight (SV) refers to the thickness of the cast iron. Extra Heavy Weight (XH) is the other kind. They can be used on the horizontal, but the pipe should probably be well supported.
Palmolive Dish Soap
Little on the rubber ring and going nice and smooth
I’ll give the palm olive and water a shot thanks youtube comment guy 👍
A little dish soap on the PVC will help it slip into the rubber seal
Greeting from 2021. Think I'm giving your method a try. Even the Fernco directions state to put donut on PVC and drive gasket into hub (What a Bear -and still an inch I can't get to seat. -thx
How did you manage to get the old cast iron pipe out of the hub?
Dig out the lead and oakum with a flat-head.

Thank you so much. I can finish my job tomorrow
Thanks bro! This was the video I've been looking for, for weeks. Awesome!
Thank you for making this
A light coat of white lithium grease would have helped seat it easily n wouldn;t hurt rubber or cause leaking..
Thank you for recording and posting this valuable educational video.
What you have is a service weight compression gasket. It will work, but Fernco makes a donut for that application. Soapy water helps and put a piece of wood on that pipe and smack it hard with a heavy sledge to drive it home.
I used dish liquid around the pipe and it’ll go in better....I used clear sealer too..
Thank you MrEnergyFree. I appreciate the instruction.
trust me try rubbing alcohol instead of water, saturat it and don't smoke
Do they make a bushing to go inside a cast iron spigot, and to reduce to pvc spigot?
Thank you for the clear explanation and demonstration buddy.
i would have used petroleum jelly to make pipe slide in easy.
Thank you so much Joel you saved me like 1000 dollars.
Did you have to put any primer or glue?
Meet my little friend,good video champ.
Meet my little friend:
Shows rubber donut for hub =))
You should of used duck butter. It’s the best this for a cast to pvc boot adapter.
just lean on it and apply pressure . But some water or alittle petroleum jelly on the end of the pipe.. It will push right in.
Thank u. The help is much appreciated
Use duck butter next time
Thank you my friend
A little bit of silicon lube make it easier.
nice job joel.
Hey. Good Video! Question? Would it be alright to use a clear silicone for lubricant?I have a metal pipe that has a small hole in it going into the cast iron.I can get to it through the closet,but its kind of tight & thought using silicone would help slide it in easier.

you can patch a pinhole with epoxy..the pipe is not holding pressure
Thank you for this, was exactly what I was looking to do. Great video!
Buen trabajo
How did you remove the old pipe from the hub
I have the same question. I need to convert some of my sewer line as well.
@FoxRcng708 I had a hard time getting enough heat to the pipe as it was only a few inches out of the concrete floor, but eventually we got it broken up and peeled the lead out.
Use a drill to drill out the lead, once enough is removed the pipe will come out. Bevelling the pvc going into the gasket is a good idea.
In Ontario Canada.....you can only use white PVC under the floor in the ground and under the cement floor...reason is that in case of fire the off gassing of the PVC is to toxic. ABS above the cement floor....all PVC under the floor.

follows the same code as' no combustibles(plastic)in a fresh air plennum.one of the other reasons to use cast iron is,its quieter
Can I use this for a clay pipe floor drain to convert to pvc?
Yes I think so but I ain't 100% sure.
Helpful video! Thank you for posting this!
I have a similar situation but the cast iron pipe I want to remove from the clay hub is cemented in. Can I safely use a cold chisel to chip the concrete away from around the cast iron pipe to remove it? Or am I likely to break the clay pipe hub?
If he had put a little soap around the pvc pipe, it goes in smoother and seals well.
Great video--just what I needed!
How do you get the PVC pipe into the cast iron hub?? It wont go in.
luckimom3 what do you mean? The pvc pipe is smaller than the cast iron pipe and will go in without it being tight and that’s why you need the rubber seal
To pass the rubber seal you can put water with soap.
grease

WRONGLY INSTALLED
Tell us why? what is wrong?
Best rubber lubricant in the world is brake fluid. That PCV will slide right in and won't harm either the rubber or the PCV.
Try it.
+moomike laloo
anything oil based degrades rubber. silicon spray should be used instead and is a better alternative
brake fluid peels paint, eats gloves, nasty stuff, I would never use it on a rubber gasket. Liquid soap is where it's at
