Leaking refrigerator water valve

New member here. Electrician by trade, and no plumbing experience besides relocating a vanity and therefore extending a drain trap.

Anyways, so my refrigerator water is fed from the floor behind it with copper tubing. I took out the copper tubing and attempted to install an in-line water filter(fridge doesn't have a filter). The plastic compression fitting that was provided leaked quite a bit, even though I felt it was plenty tight. I believe I possibly stripped the fitting. So for the time being I decided to postpone the project until I can get new fittings.

After reinstalling the copper tubing, the brass(?) fitting is now leaking in two spots. I've made sure the copper tubing is inserted all the way into the nut and properly tightened.

It appears to be leaking from the threads of the nut. It also is leaking from the valve stem. These might have been preexisting, as the linoleum flooring is bubbled up near the valve. Also, this valve does not shut off the water to the fridge despite being turned the clockwise.

My question is, is this whole assembly easily replaced? And if so, what is it called? I've reached out to my brother in law who is a plumber, but I haven't heard back from him yet. I'm hoping to get advice here as well. I'd like to handle this as soon as possible.

P.s. Also despite turning the main water off, water still comes out of this valve, but my finger is enough to stop the flow.

Thanks,

Not an expert, but the leak just below the handle (the vertical arrow) can likely be stopped by tightening the nut below the handle.

For the other leak, the blue/green salt tells me this leak has been going on for a while. If you remove the nut (horizontal arrow), you should find a ferrule, which is a brass collar that goes around the copper pipe. You may need to cut that copper pipe back an inch or so, and use a new ferrule, and reconnect it. To explain, the nut compresses the ferrule against the pipe and the valve opening to make a seal.

If, after removing the nut, you do not see a ferrule, but see a flared end on the copper pipe, I would suggest waiting for your brother-in-law, since he will likely have the flaring tool necessary.

Get rid of the entire copper line and ferrule and replace it with the proper flexible stainless steel line with the fittings attached to the line. I've seen them available at Home Depot for $10-$15 bucks. The one below is $11.

Thanks for the tips. I'll have to run out later to grab some materials.

Is that valve threaded into the cpvc or is it silicone. Something doesn't look right

Correct. Those little needle punch valves are horrible and should be replaced with a 1/4" shut off valve.

I'm not exactly sure yet. I'm going to try a couple suggestions, and if those don't work out, then I have a replacement valve ready to go. This is a manufactured home built in 1999, if that sways anyone's judgement.
