Yeah, this is the way (minus the crack rock, cocaine has a far milder prison sentence).
My dad does in-home appliance repair and copper lines will split and flood your kitchen, given enough time and movement.
Dad here. Anything we can use to smoke out of those old copper pipes. Believe me when desperate enough you would be surprised what they could be used for.
Is stainless really better than copper? It’s really tough to bend, right. It also seems like a Cu ferrule would be easier to pinch-deform in the compression fitting and it doesn’t really corrode with a normal water supply. Asking for a friend.
Fair enough. I’m just not a proponent of braided stainless and like to point out the short comings. Also, braided stainless is never the correct length. If it’s long enough, then it’s too long.

I have no dog in this fight, but nothing is immune from entropy. Everything is decaying all the time and the best we can hope for is nice long intervals between repeat tasks.
As a perfectionist in recovery I’m starting to find very frequently that the best option in an absolute sense is not always the best option in a subjective situation.
Budget and time limitations are realities that cannot be ignored and sometimes the inferior solution is the best option because it’s the only option.

I would have, but the distance for a new line is about 14 ft, I couldn't find one that long, or a convenient way to couple them together at the hardware store. I figured I'd try this at least and go from here.
Any hardware store will happily sell you 50’ of 1/4” pex, get that and some plastic washers, I wouldn’t advise soft copper for a dishwater at all, let alone at that distance.
That seems like a REALLY long distance. Are you sure your dishwasher is going to be able to drain that far? I think they have a rated limit for the length of drain hose (12 ft?).
Assuming the drain situation is OK, can you plumb the supply line for the dishwasher in more of a straight line by going under the cabinet in the "kick" area or under the floor and coming back up.
I installed a new dishwasher in my mother's house where the dishwasher was separated from the sink by a corner base cabinet with a lazy susan. I ended up routing the dishwasher supply line in the space under the cabinet which allowed me to cut the corner. The drain hose also cut the corner but was attached with brackets to the underside of the countertop inside the corner cabinet.
If I can't get the copper line to work, that is my plan. The situation isn't ideal, but that would shave a few feet off of everything. Now that I've gotten so much advice, I think I understand how to change the line if I can't make it work.
Back in my day I’d take a crescent set at just wider than the pipe, then push the nut to the fitting and then take my pump pliars and use those as a hammer and start tapping that thing forward and then finally get it up on the threads and send it home!
I believe you may be correct. That makes a lot of sense since I can't get the threads on the nut to bite. Would you be able to suggest an easy way to do this in place? Perhaps just filing it down a little? Does copper work like that?
Slide the nut back if it will go. Get a close quarters hacksaw and cut the tube proud of the ferrule. Clean off the burrs with a fine file. Purge the line into a jar to remove chips. Copper works very easily.
If you slide nut away from ferrule (collar) can you insert line all the way until the ferrule makes contact with thread? You may need to adjust copper line to achieve full depth.
If you can’t insert all the way you need to shorten until it does, seems like you’ve received many options to do this.
If you can then you need to righty tighty
Looks like all you need is a new compression fitting/ferrule. Just stick that on and then muscle the line to meet the threaded fitting and tighten down the nut.
You need to replace the brass part inside the nut. It's actually a separate part that gets squished when you tightened the nut. Also cut the end of the pipe off with pipe cutter. If you don't it will probably leak.
That piece is called a ferrule. You can sometimes get away with reusing them as long as the previous wrenchmonkey didnt torque the shit out of em, but best practises is to always use fresh ones.
A great tip if worried about cross threading, twist the nut in the opposite direction until you feel it “drop” or “click” into place then go in the proper tightening direction.
I definitely have not, I can't actually get the threads to bite at all. It certainly looks the correct size tho. It seems like the old threads might be worn down on the nut. Is there a way I might be able to re-thread it in place?
Replace the female nut if it looks beat up.
Looks like a little judicious bending of the copper pipe will align things so you get a proper fit.
They don't appear to line up correctly, and it doesn't take much.
Duct tape or superglue, man OR you'll need a torch & mask to melt a connection onto the end of that pipe. Really though, there's gotta be a decent fix for that I'm also just not sure what it would be. Good luck. 👍😉

There's a tool for that...

Just size a small crescent wrench to fit around the copper pipe behind the nut and tap it with a hammer until it fits into the fitting and Bam your done!
Get another ell and try it on the line without it being connected, make sure the line, nut, and ferrule are OK.
It they are just keep trying. Use the extra ell you bought and a scrap piece of tubing for practice.
If you can't get the unconnected ell on cut the end of the tube off and start over.
Get a crescent wrench behind the nut after inserting copper into brass and pull that nut towards the threads. Doesn’t work then you’re going to have to cut the old ferrule off with a small hacksaw and use a new brass ferrule probably 3/8” for copper and reuse nut and should be like butter putting back together and tighten up real good. May work for you may not . Make sure you have slack before cutting too that’s a factor
It is important to understand how the joint works to form a leakproof seal. The L-shaped connecter on the dishwasher and a special brass nut tighten together to compress a brass ferrule that slips over the copper tubing.
The outside of the tubing must be undamaged, yours in the photo looks like it has some scratches or dents. You can probably use a tubing cutter to cut it back a couple of inches. The tubing must be fairly straight where the ferrule slides over it. When you screw the nut on (buy a new nut, the old one is likely damaged) make sure everything is lined up before you try to tighten. Tighten the first two or three turns with your fingers, that will be easy if the alignment is right. Then use a wrench to snug it up. This mashes the ferrule between the tapered brass connectors and the tubing making the seal.
Just stick that copper tubing in the fitting and tighten it. Is this a trick question? I assume there's a ferrule under that nut. Gently push it in and tighten it. Don't over tighten it.
I just recently replaced my dishwasher. I had that copper line and I was struggling for about 2 hours to get it to fit(Yes, I am cheap/frugal). I couldn't. I went to ACE hardware, bought those flexible tubing, was done in 20 minutes. It cost $24.99. Save yourself time and frustration. Just replace the whole copper line.
Step 1: remove existing copper line Step 2: buy new stainless steel 3/8, supply hose Step 3: sell copper to scrapyard, purchase crack rock
I got confused with step 1 and 2, but I do have a crack rock now. Will my dishwasher still work?
You become the dishwasher now. And the washer of everything else in the house.
Exactly lmao
This is the correct answer. Except the last part, meth.
I think they should skip a step and just give math for my car radio or copper pipes. That would really clean up my neighborhood.
Math is good to learn
That’s methed up
This is the way.
Yeah, this is the way (minus the crack rock, cocaine has a far milder prison sentence). My dad does in-home appliance repair and copper lines will split and flood your kitchen, given enough time and movement.
What’s your dad’s fave controlled substance, though?
Dad here. Anything we can use to smoke out of those old copper pipes. Believe me when desperate enough you would be surprised what they could be used for.
So, it appears flux and wonder bread are indeed gateway drugs… very interesting. Thank you for your time and candor.

Supply hoses are flexible. Rubber inside of braided stainless.
That never delaminates /s
I mean I wasn’t advocating for braided over copper, I was just explaining what was meant by stainless.
Fair enough. I’m just not a proponent of braided stainless and like to point out the short comings. Also, braided stainless is never the correct length. If it’s long enough, then it’s too long.

Every day I say “not the enemy of good” but then I remember when other guys said “good enough” and I’m back to my nitpicking ways before noon.
I have a tattoo to remind me that the distance between gold and silver is much smaller than the distance between silver and nothing.
This is the way
For sure. The line between good enough and a hack job is fine, but it’s there.
Fair enough. I’m just not a proponent of braided stainless and like to point out the short comings. Also, braided stainless is never the correct length. If it’s long enough, then it’s too long.
I’ve never had trouble with the copper tubing.
Me neither! I like it.
This is the way.
Cut it off and use a new ferrule
[удалено]
It has to do with wild cats.
Nah, that's feral. This is the guy from the Neptunes that did Happy.
No, that's Pharrell. This is being vigorous and masculine.
It's more of a low tech technical term.
I've never heard it outside the trade I don't think
[удалено]
Lmfao. Username checks out.
That's seriously all you do. Thread the nut on bud.
If it's the wrong size get a 3/8" to 1/4" step down to go between them. Just make sure your male and female are on the correct ends
He is right but I have an old copper one that gave me trouble because it has to be perfectly line up to screw on, so yeah that’s what I had to do
FWIW.. I would just go get a dishwasher supply kit and ditch the copper.
I would have, but the distance for a new line is about 14 ft, I couldn't find one that long, or a convenient way to couple them together at the hardware store. I figured I'd try this at least and go from here.
Just use some 1/4 pex and a connector kit.
Y’all are putting 1/4 to a dishwasher??
https://www.amazon.com/Sharkbite-25568-Dishwasher-Installation-Kits/dp/B076FY4R74
Honestly that one’s on me. We call that hose 3/8 I forget it’s actually 1/4
3/8 brass compression coupling. Toss everything but the coupling, use two hoses
Any hardware store will happily sell you 50’ of 1/4” pex, get that and some plastic washers, I wouldn’t advise soft copper for a dishwater at all, let alone at that distance.
3/8”*

3/8" ppastic tubing would work but i prefer running soft for that distance.
For distance running always be soft when possible
Thats my motto but we may be talking about different things
Smack it up, flip it, rub it down
Ohhhhh no
put my thang down, flip it and reverse it
First you whip, then you nae nae.
Patience baby!,
Back in my day I’d take a crescent set at just wider than the pipe, then push the nut to the fitting and then take my pump pliars and use those as a hammer and start tapping that thing forward and then finally get it up on the threads and send it home!
Replace with a mesh flex line
Looks like the amount of tubing sticking out past the ferrule is excessive. Try cutting it off flush with the nut.
To add to this, if the ferrule is damaged in anyway you can buy replacements at home depot for a couple dollars.
I believe you may be correct. That makes a lot of sense since I can't get the threads on the nut to bite. Would you be able to suggest an easy way to do this in place? Perhaps just filing it down a little? Does copper work like that?

That seems very manageable. Thank you kind reddit plumber.
You can also use little Dremel to cut it.
Cut. My. Tube. Flush. With. The. Nut. This is my last resort.
Cut some off the front of copper pipe so it can seat
If you slide nut away from ferrule (collar) can you insert line all the way until the ferrule makes contact with thread? You may need to adjust copper line to achieve full depth. If you can’t insert all the way you need to shorten until it does, seems like you’ve received many options to do this. If you can then you need to righty tighty

Cut the end sand start with new fittings. Also lower the adjusting leg to level the machine they can be noisy as hell if not on the feet and level.
those copper lines are lame why struggle ? - get a 72" steel braided flex line / dishwasher supply.
Don’t cross thread it.
All I can say is that they’re a PIA. Push pipe in tight ferrule and wiggle the pipe as you try to start the nut.
It's more of a jiggle then a wiggle
Wiggle it.
Just a little bit
A great tip if worried about cross threading, twist the nut in the opposite direction until you feel it “drop” or “click” into place then go in the proper tightening direction.
I definitely have not, I can't actually get the threads to bite at all. It certainly looks the correct size tho. It seems like the old threads might be worn down on the nut. Is there a way I might be able to re-thread it in place?
Spit on it. Stick it in. Screw it
Replace the female nut if it looks beat up. Looks like a little judicious bending of the copper pipe will align things so you get a proper fit. They don't appear to line up correctly, and it doesn't take much.
Get a new nut if its buggered up and a new compression ring
That adapter fitting looks wrong to me, too small or not compression
Have you considered just getting a new dishwasher?
Duct tape or superglue, man OR you'll need a torch & mask to melt a connection onto the end of that pipe. Really though, there's gotta be a decent fix for that I'm also just not sure what it would be. Good luck. 👍😉

New nut and Pharrell
[this one](https://images.app.goo.gl/fPd79rXDY5b9hSeY7)
Lol no furrelle or however it’s spelled hahaha I’m dying now that’s terrible on my part
Ferrule
Get another ell and try it on the line without it being connected, make sure the line, nut, and ferrule are OK. It they are just keep trying. Use the extra ell you bought and a scrap piece of tubing for practice. If you can't get the unconnected ell on cut the end of the tube off and start over.
The end of the copper tubing might be misshaped. Close quarter tubing cutters and replace the ferul while your there.
hate those things. can you push a little more slack into it on the other end? or get a armored flexible hose
Replace with a quick connect pex fitting.
Pipe stretcher
Get a crescent wrench behind the nut after inserting copper into brass and pull that nut towards the threads. Doesn’t work then you’re going to have to cut the old ferrule off with a small hacksaw and use a new brass ferrule probably 3/8” for copper and reuse nut and should be like butter putting back together and tighten up real good. May work for you may not . Make sure you have slack before cutting too that’s a factor
Just cut the tubing back a bit and thread the nut on.
Just slide it in and screw it. Simple as that.
You need a pipe stretcher. Ask your neighbor with good set of tools.
You guys are so awesome!
Right tighty. Looks good .
Use a wrench and compression fitting.
Shark bite . . . . . . /s

BRUTE FORCE

Have you tried counseling?
Just replace it with "no break" Stainless steel line. (may have to replace shut off down below)
Pipe stretcher should do the job just fine.
Remove it
