OK, installing dishwasher..........USE NEW WATER SUPPLY STUFF OR REUSE OLD???

[redgtxdi]

OK, so the depot dropped of a dishwasher yesterday & I'm all ready to hook it up where the old one left off......but.....

Delivery guy made me think twice. He said, "You should get a new water supply kit".

WTF?? I've disconnected/reconnected sinks, toilets, etc w/ compression fittings and always reused the old ferrule and nut.


What's ATOT think?

How old is the old stuff?

Yep if it's recent no need to but it really depends on how old it is.

Switch to pex since it's easier to work with. Not that I'd know, I have yet to tackle plumbing yet in my house. I'm too chicken for that so I stick to electrical. I want to learn it though. I fixed my parent's toilet intake and so far it has not flooded the basement, so I'm probably scared for nothing. If you do things right then it works well.

Ya, heard of pex and sharkbites or whatever they're called. Crazy stuff (expensive though).


The entire house is 13 yrs old. This is the first time that connection's ever been removed. The elbow looks good & the ferrule has small marks on it from the original compression, but ???

Or maybe just get a new ferrule & nut??? (Do they sell those?)

I CERTAINLY don't want to put a whole new copper line thru there. All it is is a cut length of copper......there ain't nothin' special about that, but I have a feeling that's what the water-supply kits probably come with. (???)

Get a new one. They are a trivial amount of money and it's better than running into a problem later due to your laziness now.

Been there, just take a tube cutter and cut off about 1/4" past the old ferrel, then slip on a new nut and ferrel. Nothing to it. The copper tubing should be fine.

The water supply kits come with plastic tubing. They probably recommend new so you don't damage the plastic line and end up flooding your house because it starts leaking when you are gone the next day.

Probably all the more reason to reuse copper rigid one I have, no???

This.

Since the two guys with 1's at the end of their names solved your problem, I'll ask. What did you get???

My brother and I replaced our parents' dishwasher; we just pulled out the old one and put in the new one. We didn't replace any pipes but it's been running fine for years.

Personally, I'd get a high quality, braided hose to go from the shutoff to the dishwasher connection. But, I can see no reason not to reuse what you have. Yes, they sell the ferrules separately.

 

[redgtxdi]

Well, my advice to anyone doing this would be......DON'T!!!! Just buy it from somewhere that includes installation. It's worth it.


Ended up getting the braided stainless hose kit. (just 5ft of hose and the brass elbow --- $10) My thought process was I recall the rigid copper wasn't exactly easy to undo and feeding back in would probably be another pain. Having the braided flexline would make it easy to do all the hookup work with the dishwasher out and then I could feed all three ......

1.) water line
2.) drain line
3.) power cord

...... all through the cabinetry and that would just make things a lot easier than trying to thread that other crap on whilst working with about 4" of wrenching height!

Great in theory.....sucked in reality. Problem is all the instructions don't want you to overtighten....(hand-tight, then 1/2 turn, no more). Bzzzzzzzzzzzzzt!! Wrong answer.

First I had a leak at the elbow (yes, I used teflon tape)

Then after I turned that around one more full turn (remember it has to face toward the back cuz in 100 years of industrialization, dishwasher manufacturers haven't yet figured out how to get a fitting installed that ALREADY points backward) and that stopped the leak there, but now allowed for a new leak at the nut on the braided line.

Removed braided line (AGAIN) cleaned all threads (remember, no teflon tape on those) and reinstalled. Tried water again, left it on for a while.......VOILA!!!

When in doubt..........tighten more than you think!!!!!!!!!!!!

Dicked with the leveling feet whilst trying not to rip the fleece blanket to shreds, got a good level/plumb install. Test ran it......looked the bitch up & down. Cursed her real good like the ho she is......loaded that sumbitch and walked over here to the laptop.

/night

Eh, after a while you get the hang of how much to tighten those joints. Especially things like the elbow with the pipe tape on it. I personally like the braided hoses for the reason you suggested - much easier to monkey around with, feeding it through, etc. I installed my dishwasher 2 1/2 months ago; I think the entire installation took 10 minutes. And, next time you deal with a brass elbow or braided line, you're likely to get it right the first time. Just think - had you used the old copper, you likely would have still had the problem with the elbow. And then it would have been much more of a pain in the ass to deal with fixing that with 4" of space.

We charge $120 to install a dishwasher, plus a new kit ($25) which includes a Pex line, new elbow, new power cord, and wire nuts. The stainless steel braided hoses are what we used to use, we find the Pex lines are even better. We do not reuse copper lines, unless there is no way to replace them. After 13 years, the copper could be much harder than it was new, making it difficult for the ferrule to crimp into the line. Then there's the whole easy-to-kink thing. Copper supply lines are basically an invitation to leakage.

DrPizza, if your whole install only took 10 minutes, you had a textbook situation! Count yourself lucky

 

[redgtxdi]

Ya, I hear ya. Still sucks though!

At least the flexlines appear to be reusable so taking it off and putting it back on 2 or 3 times didn't matter whereas I'd have not felt good about re-crushing the ferrule type trying to figure out why the F plumbing is still so old school!!!!!!

Even on the bathroom reno I'm currently doing, the 20-year, licensed/bonded/insured plumber who could probably sweat copper in his sleep, got all done, then turned on the shower mixer valve with a cap up where the head would be and said, "Well, let's leave the valve open like that for a couple days & see if any leaks show."

WTF?????

Fact is, nobody knows!!! Could leak. Could be fine.

Fsck that!!! Give me something mechanical!!

I hate plumbing!!!

Although the position usually makes the job suck abit, when I changed out all my appliances last year it was relatively easy to change out the dishwasher. I did buy a new hose and fitting just cause I didn't want to pull it out again in case it developed a problem at the joints reusing the old. Like 8 bucks for the hose and another 5 for the elbow fitting.
