Hi, I currently have a broken stop valve under my bathroom sink. it is a sweat type valve. Can this be replaced by a compression type that I can do myself?

What is actually broken on the valve is the turning knob. The valve itself is metal but the knob was plastic and the threads on it apparently are stripped because I can turn it but it doesn't actually open or close hte valve. I suppose just replacing the knob and perhaps the screw would work if anyone has thoughts on that. Thanks!

Probably. If you can cut the old valve out (tubing cutter is best but a hacksaw will work) and use a short piece of new tubing (attached with a comression fitting) to make up the length difference it should work to put in a compression valve. Make sure the tubing is clean and round and has no burrs on the end before tightening the compression nuts.

Yes. The easiest way to go about this is to cut the old valve out with a tubing cutter. If you have to, you can use a saw. If you use a saw try to cut as straight as possible and remove any burrs. When you install the new valve make sure that you attach it to a section of tube not covered in solder or other debris. Do not overtighten, you should tighten hand tight then use a wrench to tighten one more turn. If necessary you can tighten it more if it leaks at the joint.

Yes, you can replace a sweat, or soldered, joint with a compression. You may want to try replacing the guts of the valve first tho. Since you do not elaborate on what is "broken" its hard to give you advice there...
Whatever approach, obviously, don't forget to turn the water off, lol
If you are going to use a torch, but something between the pipe and the wall, so you don't set fire to the wall, hehehe.
Good Luck!

The problem you may run into is the difference in guage between sweated copper and compression copper. The sweated copper will have a thicker wall thickness, but I can't say whether it will have the same outside diameter.
I would look to see if you can replace the valve bonnet and internals first. Check with a good hardware store where they don't hire kids. You'll need someone who speaks the language.

Yes, if you have about 1 1/2" of pipe to work with behind the solder joint. Use a mini tubing cutter and cut as close as you can to the solder joint.
You may also take the stem out of a new valve and put it in place of the stem on the old valve. ***much easier***

yes, simply use a hand held torch, heat up the solder on the sweat valve, remove the sweat valve, use emory cloth to completely clean the pipe and remove all solder, slip your compression fittings on and tighten up....hope this helps...
