[@garytencer117]

Thanks very much Bob. Your hint about using a pipe to tubular coupling saved me a lot of anguish when I had to redo my drain when we installed a new deeper kitchen sink. The old galvanized nipple going to the trap was rotten at the brass elbow and a bit too long for the trap to fit. Cutting the nipple back and installing the coupling worked perfectly. Mind you that I like my plumber friend but I can't shed my DIY addiction. Thanks again.

Wow. Thank you Bob for opening my mind and solving my problem. I have a rusty undergrond 1/2 inch galvanized water feeder line extending into my back yard which long ago had been capped off (leading to no where). Recent sewer digging upset the pipe causing it to leak along its course. I cut out the leaking section (about 6") with the intention of simply capping it, since the end is not threaded. I thought that I could grind it off at the end and epoxy a pvc cap on it. That didn't work. It leaks. The no hub coupling looks like a good fix. Thank you. Don in Davis, Ca.

[@BobsPlumbingVideos]

Donald Wilson Thanks for checking out the video Donald. No hub couplings are for non pressure drain lines, not to be used for water pipe ( pressurized) lines. For 1/2” galvanized water pipe I would use a dresser coupling.

Fantastically helpful. Thank you so much. I'm housesitting for some people who's kitchen P-trap was held together by faith. Not surprisingly, it leaks and blew. I snaked and rinsed it out, but that's only a temporary fix, because none of the joints are tight or sealed. This gave me some great ideas on how to repair it so that it lasts and yet will still be easy to clean out.

Excellent! Just one question. Is there any male pvc or abs adapter that can connect directly to the female thread steel? To avoid having to use the rubber coupling.

[@BobsPlumbingVideos]

They make 1 1/2" and 2" male and or female adapters for both P.V.C. & A.B.S. Glue it onto the pipe and screw it into a female galvanized fitting.

[@flipper2473]

Hello, I plan on replcing a ancient backwater valve in my basement. I was planning on using the corrugated metal coupling because I can easily fold/roll the rubber over the 4 " cast iron to make room for the pvc that will be within a 1/16 " from the cast iron. A plumber told me to use the smooth stainless steel shield proflex 3000-44. That rubber is vitually impossible to stay rolled back while I line up the pvc to cast iron. Is it ok to use the corrugated metal shield coupling (4") for my application, and are there any tricks in connecting / rolling the thicker proflex 3000-44 hub over the cast iron ? Thanks

I've ended up on this video twice in the last 6 months as the last of the galvanized pipe is failing. Thanks for sharing all the options for connecting the stub to sink drain with no-hub couplings. Saves me many trips to Home Depot as I can go there with a plan.

Options, just what I needed! Same boat with the galvanized pipe. I see it, it makes sense, but it seldom works out for me like in the movies. I'm thankful the big box is only blocks away.

[@sunnifreyer2759]

So I am trying to connect plastic pipe from p-trap under my kitchen sink to the galvanized steel wall drain pipe which is pretty short. Someone else said I should use a 1 1/2” brass waste adapter to connect the two pipes. Now I see this. Hmm. Which is the better route? Whoever connected them before me put a slip joint on the steel pipe, without a washer, and then put the PVC into the drain pipe. There was no seal! And because both pipes are 1 1/2-inch the plastic pipe only went inside the steel pipe about 1/8 inch or so. Of course, the plastic pipe keeps popping out under pressure. I'm trying to do it correctly. Suggestion on which route to go? Your idea seems like a good one to me and you're the pro! Thanks for giving back to the world!

[@m.n.3490]

Do you have any videos for dealing with galvanized pipes that are rusting, and starting to leak? I have a basement 3/4" pipe that has a rust 'bump' that has a drip. I was trying to decide between (1) wire brushing the rust bump down to level it with the pipe, and then using a compression clamp like maybe a (3/4" x 6" Stainless Steel Dresser Handiband Repair Clamp) ... versus ... (2) sawing about 2" of the rusted section of galvanized out, and then replacing the rusted section with a 4" long, galvanized iron Compression Coupling. Or, (3) my other idea, since I already have a older clamp that is getting rusty, about 6 feet from the newer drip, maybe cutting about 6 feet of galvanized pipe out, then using two compression couplings (one at each end), and then putting a galvanized nipple pipe, and a "shark bite" pex fitting at each end, and then placing about 6 feet of pex, in place of the removed 6 feet of galvanized. (I am guessing I would need to support the pex somehow, since it would be around 6 feet long, running in parallel to 2 rafter joists in the basement). After watching your video, it looks like I could use those no hub coupling also? Or would the weight of the longer run of galvanized preclude using no hub couplings? Or, maybe just require some more support also?

[@BobsPlumbingVideos]

The video is for drain lines only (no pressure), no -hub couplings are specifically for drain lines. If you're talking water pipe (pressurized) I would be inclined to cut out the bad section and replace it with either new galvanized pipe or c.p.v.c. (if legal ) in your jurisdiction. SharkBite fitting is the quickest way to do it, but here in N.Y.C., we're not allowed to use them. You'll definitely need to support the c.p.v.c. if that's the way you want to go. Not 100% sure on this but I believe for a 1/2" pipe you'll need a 3/4" shark bite fitting. If you don't want to open a can of worms, the pipe clamp method may save you some headaches.

[@Anubalfer]

After putting the thread tape on the nipple you said to use joint compound. Any recommendations here? I'm just putting a new nipple in and putting the tube in with a nut and washer.

We have an old sprinkler system where the supply line is galvanized steel. It would be much easier to work on repairs if I cut it back and transitioned to PVC so I can rebuild by valve manifolds. Will this transition work on a sprinkler supply line to go from galvanized to PVC?

Very informative. And, in addition to showing several transitions, you also made me realize the difference between 'pipe', and 'tube'. I've been calling everything 'pipe'. But, seeing the difference in your video between in 1.5" galvanized 'pipe', and 1.5" stainless steel 'tube' - was educational. Is the 1.5" the OD on the 'tube', and the ID on the 'pipe'?

[@Missconduct044]

Hey bob, I have a cracked kitchen drain “waste” pipe. It’s not the pipes under the sink but the one that ties in the main sewer line. The existing pipe is steel. Is it ok to replace the steel cracked pipe with PVC? I kind of don’t want to replace the entire pipe, just the section that’s bad. So that would mean I need a “coupler” that would be PVC to steel. What would that coupler be called? The existing pipe is 1 1/4. None of this is underground. It’s in a crawl space. Thanking you in advance bc I see you do respond. It’s actually awesome that you respond!!

[@Missconduct044]

Just to clarify I feel like I can and I guess I’m just looking for reassurance. lol! The existing steel pipe has threaded connectors, but it looks like it’s soldered as well. That’s why we were going to just cut it out.

Very little choice when working with 3/4" galvanized pipe. This video demonstrates how to transition between waste pipe which is not pressurized. If you can't get a thread onto the galvanized water line, my only thought would be a 3/4" "dresser coupling" which I would not recommend for a permanent solution. I use them to make temporary repairs until I can thread and make a permanent fix.

Can you transition from galvanized to pvc in a pressured system, approximately 50psi? My water pump piping, which has been in place for a long time is galvanized. Because I have decided to have a pool installed, some of the pipe needs to be re-routed and I would like to transition from the galvanized to a pvc. Is this the best way to do that?

PVC is for drainage lines, for pressure you need to use c.p.v.c. And you would need to use a combination of I. P. S. ( screw) to glue c.p.v.c. Fittings. No no-hub couplings. They are not meant for high pressures.

Use an 1 1/2" X 1 1/4" coupling nut and gasket, slip the 1 1/4" p.v.c. trap into the male adapter and tighten the nut and gasket. You should be good to go!

Hello bob I have an issue my p trap cracked past the nut... do I cut the rough part back a little heading into the wall and start a pvp coming out of the wall and start a whole new p trap?

OK so, we had a water leak on the main water line at the connection point. Now the water line coming from the street is PEX then whoever fixed the original leak used bicycle tube, a radiator hose clamp and tape to connect to the galvanized.. The PEX pipe is 3/4, the galvanized is 1/2, what is the easiest way to fix the gap between the two..... we have e been told several different things, and it still continues to leak.

[@BobsPlumbingVideos]

The methods above are for drain pipe only! To make the transition from 3/4" to 1/2" I would go with a 3/4" X 1/2" Sharkbite fitting. Is the 1/2" galvanized a male or female joint? Depending on which you could use a male or female Sharkbite adapter. Place the 3/4" Sharkbite coupling onto the 3/4" PEX, then using a piece of 1/2" PEX tubing and connect to the Sharkbite adapter on the galvanized pipe. This may help you -kzbin.info/www/bejne/Z3_UmGuVqcinrq8

I can transition to pvc to bring hot water outside from galvanized?

I have a 1-1/2 inch pvc threaded male going into a galvanized steel tee. Is it okay to use teflon tape for this connection? Thanks.

[@BobsPlumbingVideos]

Some disagree with me but I have no problem using Teflon tape for this type of connection. I would also recommend an application of MegaLoc or Blue Block pipe joint compound over the Teflon. That’s how I do it. Regards, Bob.

[@vgbr88]

@@BobsPlumbingVideos I have plenty of teflon tape and the old pro dope gray stuff leftover from when my dad was a plumber in Brooklyn over twenty years ago. Is the pro dope safe to use over the teflon on the pvc, or should i buy the MegaLoc? I had to make a hole in the bathroom wall to access this pipe, so I want to make sure it doesn't leak. Thanks for your help. I enjoy your videos very much.

[@BobsPlumbingVideos]

FixItYourselfAndSave ProDope brings back memories and they still sell it. I would go with the MegaLock. It’s Teflon based and shouldn’t effect the tape.

[@wjenks4916]

I'm having a problem removing a metal pipe (galvanized or steel) that's rusted through the bottom side and leaking. I've tried patching it up to stop leak, but that's not working well. how does a novice like myself get that pipe off without messing something else up? I think the metal pipe is actually the nipple, it's about 3-5 inches long, and it carries water out. HELP!!! LIST OF TOOLS AND SUPPLIES I NEED TO DO JOB!

[@kyakarrenamiyaan]

can something similar be done for main water line running inside the walls

[@BobsPlumbingVideos]

These are for waste lines only, not meant for high pressure!

[@BobsPlumbingVideos]

No, the no-hub couplings are designed for drainage / waste lines only. Not meant for high pressure.

[@evergreenavevergreenav8264]

Knob coupling, Laub Coupling... which is it? I can't tell exactly what the name of the coupling is exactly

[@BobsPlumbingVideos]

No-hub coupling

[@kennylunaaa5596]

Will this hold in the ground?

[@BobsPlumbingVideos]

For underground applications these are the go too couplings - www.anaco-husky.com/products/husky-7000-series/

[@ARTMANIQ]

Hi Bob; what's the operating psi? Can this connection be buried underground? Thanks.

[@BobsPlumbingVideos]

+ART MANIQUIS Max test pressure on the coupling illustrated is approx 4.3 psi and technically they should not be buried. For underground applications, these are the couplings to use: abifoundry.com/upl/downloads/catalog/products/husky-4000-submittal-edb31228.pdf. Thanks for watching, Regards. Bob.

[@lukesmith2725]

VERY insightful. Thank you!

[@RonRova]

This is exactly what I needed. Even the layout is very similar to mine, except I don't think the old nipple will come out. The idea of using tubular is new to me but definitely going to consider it! Thanks!!!!

I am trying to connect 3 inch pvc to cast iron. The cast iron is slightly smaller than the pvc. Can I still use these rubber connectors?

[@BobsPlumbingVideos]

This should help - www.usplastic.com/catalog/item.aspx?sku=31287&gclid=Cj0KCQjw9uHOBRDtARIsALtCa96VqnjzifYOVvb1V9A8aa0uO_M-94_k5cF7DkK8dxeFQA95GLWpBVsaAv1_EALw_wcB

[@jackjones3657]

Is there an advantage to ABS vs. PVC? Thanks for video!

[@BobsPlumbingVideos]

I don't know? In my area schedule 40 p.v.c. along with cast iron are the materials of choice. I very rarely if ever use abs only because you don't see much of it here in the N.Y. City area.

[@simpleton8554]

Im not a plumber. But i do hone repairs. I have been trying to connect pvc to metal and it just keeps leaking ugh

[@BobsPlumbingVideos]

Simpleton They make a variety of no- hub / Fernco couplings to connect a variety of materials for a leak proof joint. What materials are you trying to connect?

[@simpleton8554]

Im not gunna lie bob its a mess. My granmother lives in a old trailer and can not afford a plumber. 2 half inch galvanized water pipes to the shower was sitting on a beam for about 15 or more years and rusted and blew out. I just figure buy 4 half inch couplings pvc and take a saw zaw knock out the bad in with the new. I did all that. I used the glue. The couplings was a little tight but i hammered em on. Still it leaks. Very high pressure. The system cant be redone its all rusted and stuck together. Has to be patched..:(

[@dreadnought2024]

Is what I was thinking of doing. Just needed conformation. Thanks!! ;-]

[@BobsPlumbingVideos]

Glad I could help!

[@jacksplumbingvideos7147]

2:41 those are the traps I like to use. I hate the tubular traps.

[@user-gx7yn8pn9c]

What about going for steel to copper

[@JohnWilson-xi2wu]

Good video.Very informative.Thank you.Couldn't you use a pvc adapter right from the tee behind the wall?

[@BobsPlumbingVideos]

Absolutely, If you have the room. Go for it! HAPPY PLUMBING!

[@sbmang4927]

What if the inside of the drain pipe doesn't have any threading?

[@BobsPlumbingVideos]

Has no threads or very worn threads? If they're worn down I try to cut new ones with a pipe tap. If no threads you're going to have to open the wall and replace the fitting.

[@trevosride]

Excellent explaination thanks

[@ترانهحخذا]

Thanks for sharing this video. Very helpful to me.

[@BobsPlumbingVideos]

My Pleasure!

[@hectormeza991]

Any idea on the psi it can handle??

[@BobsPlumbingVideos]

No-Hub couplings are designed for waste lines only. They're not for use with water lines, I'd say 30psi tops!

[@parasharakandula7076]

Hi Bob, I would like to join 250 mm dia HDPE pipes using PVC coupler. If so, what type and make of adhesive to be used. This is for electrical underground HV cable application.

[@BobsPlumbingVideos]

Not familiar with HDPE pipe. Send me a link and I'll check it out!

[@ericduplantier9691]

Parashara Kandula not sure what size 250mm is but my local HDPE sells connections already made with PVC on one side and HDPE on the other and just fuse the HDPE and continue with PVC to where you need it

[@ericduplantier9691]

My local supplier

[@neilwilliams8608]

How come there are no videos on how to use PVC male and female adapters to metal pipe? Awesome video. Thanks a lot.

[@nancypants3723]

If one fastens threaded couplings of different hard materials there's a good chance that connection will leak. With my luck, I can pretty much count on that. Two choices I know are either a rubber connector "with" the metal band or use an dielectric fitting. Ferncos are cheaper.

[@MJ202020]

Thank you super clear explanation

[@BobsPlumbingVideos]

michael shapiro Thank you for checking out the video! Regards, Bob.

[@sirjohnahayfalcon]

how do a connect a galvanized water line without threads to pex???

[@BobsPlumbingVideos]

What size are we talking about? Is this for heat or water? If 1/2" or 3/4' you're going to have to put a thread on the pipe and use a female pex adapter!

[@sirjohnahayfalcon]

oh wow, this is from a water main line. i appreciate it the guys at the plumbing shop gave me bad advice i really appreciate it no wonder it was leaking after i re-piped the whole house was annoying. ok guess i will have to go deeper and see if i can undoe the galvanized at the threaded part. probably have to use penatrating oil and heat? i really appreciate this advice

[@BobsPlumbingVideos]

Take a few photos and e-mail them to [e-mail]. I'll see if i can guide you further!

[@sirjohnahayfalcon]

thanks alot bob you are superior here is what im talking about, i had to cut off the galvanized with a grinder, but its the pex side that leaks i used the metal washer and rubber gasket you can see the leak in this pic i7.photobucket.com/albums/y256/honigga/Mobile%20Uploads/image_zpsa7e68214.jpg

[@BobsPlumbingVideos]

I'm guessing that's a 3/4' dresser coupling I'm looking at? That will take care of the galvanized side, and on the pex side I would go with a 3/4" female ips to whatever size pex adapter. Screw a 3/4" x 5" or 6" nipple into the pex adapter and slip the dresser coupling over the nipple. The only other choice is to thread the galvanized pipe in place, which can be risky. I'd stay wit the dresser coupling! good luck!

[@lachellefarmer8265]

Very helpful thanks for sharing

[@matth523]

how about for pressurized supply lines? same or what?

[@BobsPlumbingVideos]

Not for pressure lines, only drain lines!

[@matth523]

what do i for pressurized lines then?

[@BobsPlumbingVideos]

What materials are you trying to join?

[@matth523]

galvanized to pvc or should I just do it all with galvanized?

[@BobsPlumbingVideos]

I'll assume 1/2" pipe ? Same for all sizes, I would transition to all C P.V.C. You'll have to use either a male or female C.P.V.C. adapter. If you're screwing into a fitting use a male adapter, If you're screwing onto pipe use a female adapter. amzn.to/2aUM43O or amzn.to/2b6Lcgr C.P.V.C.for water pressure, don't use schedule 40 p.v.c. pipe which is for drains only!
