I plan to replace sink faucets. I found out that one of the shutoff valve under the sink does not shutoff completely. The house was built in 1992. So I plan to replace both shutoff valves with quarter turn valves. The current shutoff valves are soldered into the line coming out of the wall. The question is whether to use sharkbite or compression fitting. Soldering is out of the question (zero skill). Any suggestions/recommendations are appreciated. "
 
Thanks. Got the compression valves and Emory cloth. Hit it hard tomorrow
 
Won't you have to melt the old solder to get the old valves off? otherwise the tubing might be too short for the compression fitting. whatever you use you need to get most of the solder off the tubing
 
Post a pic of each valve, showing how much copper line is available and its condition.

Quarter turn valves are great, but if you will have a tough time installing them, it would be easier just to replace with the same type you have now.

Pics will tell the story.
 
Here is the pic.

I think they will fit each other.

You are going to have a lot of prep work to get that copper stub ready to receive a brass ferrule for a new compression style valve.

I would get two new valves, compression or solder type doesn’t matter, that have that same football shaped handle and exact same configuration.
A multi-turn valve, not 1/4 turn.

As in, 1/2 inch copper to 3/8 compression, right angle.

Then it is extremely likely that you can just unscrew the big nut right behind the handle, and unscrew the whole guts inside the old shutoff, clean out any crud in the valve, and replace with the same part from a new valve.

When installing the new stem, leave it a little bit less than all the way turned in before tightening the big packing nut that holds everything in.
Otherwise it can bottom out too hard and break the plastic stem.

You can fully close the valve stem after the packing nut gets tight enough.
No need to make it super tight, just secure so no leaks.
 
Here is the Brasscraft version.
The wrench diameter of the packing nut looks a little smaller, but the female threads and guts inside might match up ok.

I believe Home Depot carries Brasscraft.
Maybe they carry the rebuild kits also.

If you end up using your 1/4 turn valves you already bought, you could try wrapping the copper stubs in small rags or paper towels soaked in pure vinegar, then put plastic like a grocery bag around that, tape it up, let it soften up that junk on there overnight at least.
 
I am going to return the compression valves I bought at Lowe's and see if I can get Eastman valves and swap out the innards. Thanks everyone for great help.
