My dishwasher started leaking over the weekend. I turned off the water at the shutoff in the basement, it's a standard faucet type in the copper piping.
I then replaced the rubber heater hose used to feed water to the dishwasher, which had sprung the leak.
Trying to turn the water back on, I realized that the valve isn't opening. It turns repeated, and I've turned it many many times, but no water is flowing.
Is it possible that while turning off the water I stripped the thread, broke a washer, etc, stopping it from opening?
How can I fix this? Is it like a normal faucet that I can turn off the water to it, remove the packing nut, and replace the valve or whatever has broken underneath?
The valve itself looks something like: http://i.ehow.com/images/a06/6q/tm/plumbing-water-stop-valve-installation-200X200.jpg http://www.brass-plumbing.com/productsimages/brassneedlevalve_95381.jpg
Looking at those, what I'm wondering is if I can just remove the handle (which is broken anyway, I got a little rough), remove the packing not, emptying out the body, and replacing the contents with the header, nut, etc from a new valve. So I don't have to unsolder, the whole thing.
Also, valve and shutoff are new tag, so I can't create them, but would probably be relevant.
