Dishwasher: keep or replace rigid copper supply line?

I am having the same issue as DIY in this old thread.

My new dishwasher is being delivered TODAY. I installed the last one 13 years ago and plan to install this one too. The store asked if I wanted new stainless steel hoses.

I declined. After removing old dishwasher I find the copper line is BENT. Need to verify it does not leak at the crimp.

IF it leaks, can I repair easily?

On a side note, i noticed my garbage disposer is leaking from below. It's probably 10 yrs old at most. Can I plug the leak? My kitchen is original (60s) and I wasnt planning to gut/remodel for another 6-18 months.

Considering this...
How to Replace a Dishwasher - Part 4

I hear/read that copper lasts forever, but what if it fails?
Yes, I know the copper is pricey and intend to reuse or sell for scrap to offset my expenses.

Copper is the LEAST likeliest method to leak or fail.

The method you choose is based on what you have and what you have room for.
I ran soft copper right to my current dishwasher and the same to the one before it. Copper is a little harder to work with as it does bend/kink if not carefully handled.

You should be able to replace the kinked copper feed line you have. How long can it be.... a few feet ?

I am not a plumber...no tools or exp sweating pipes

What's can I do today to get this installed?
No instructions with delivery so I am downloading from mfgr and printing what I need.

Good grief I don't remember it being this difficult 13 years ago! I can't find the electrical hookup and the water hookup is prepped for hoses. Ugh! I suspect an expedition to the parts store is on my agenda today.

Thanks for responses so far. Much appreciated!

If your machine is prepped for a hose then you can either solder the correct fitting to the 1/2" pipe right after the valve or use a Shark bite fitting.

Take the hose you have for the dishwasher to the depot. Tell them you want to connect it to a 1/2" copper pipe. You can use a fitting like in the following link. It's a sharkbite fitting... it just pushes on.

SharkBite 1/2 in. Brass Push-Fit x MNPT Adapter-U120LFA at The Depot

Hi Some dishwashers have a different water hook up and the old copper fitting won't work.
I would suggest You buy the kit ( comes wity adapter and ss flex line). You will also probably need a straight angle stop. One end to fit the flex line and the compression end to fit the pipe in your picture looks like 1/2 inch. Shut off the water and cut the tubing off where it connects with the 1/2 pipe as far away from the existing valve as possible. Clean the end of the pipe off then install the angle stop.
Good Luck Woodbutcher

installed FINALLY

Thanks all. I wound up cutting off the copper line including the valve that needed a new seat. I used a quick connect ball valve (no sweating) and SS braided hose with 90 connect.

No leaks. Yay! Well...except for the bottom of disposer.
Guess what I get to buy/install tomorrow? ~sigh~

Thanks soooooo much for your help.
