Remove Old Valve and Supply Line

this angle stop supply line combo right here you can see it this is corrugated copper i'm actually going to save this from this job and we'll talk about them because they really are bad i've seen these things flood a lot of homes when they break this is a one-time use when you take this and you pull this out of this valve and you try to put it back in that valve there is a good chance that some part of this corrugated copper in here is going to break you don't want to reuse this so we're going to remove it this is a very easy thing to do if you have the right tools right so right here i have a one stop wrench this actually is going to allow you to get on here and hold this down we're also going to need another crescent wrench or adjustable jaw wrench for this with these right here what i like to do is because this one piece supply line combo it kind of it makes it a little bit more difficult to mess with to actually even work in here so i just actually take this thing and you can see how easy this breaks off it just broke off very quick so we'll just take that get that out of our way and now we'll be able to get in here and we'll be able to hold this down nope we're gonna need the bigger wrench let's see yeah perfect so we can use the smaller wrench but that's all right so just grab the bigger adjustable jaw you're going to want to spin the valve itself counterclockwise while holding the backup on the other nut you want to make sure that you have this backed up because if not the whole thing will spin or never get it out okay let's actually use this right get that right leverage there oh okay that bad puppy is okay so we're able to actually get we weren't able to spin the valve but we were able to spin the back nut which is good okay so now this whole thing is kind of coming loose right we're able to take this we'll just hold it i can see why i think they put a little plumber's putty on the threads to seal this whenever they put it together it could be pipe dope but it looks like it's a plumber's putty you might want to put a sponge or something down you might still get a little drip we just got a little toilet paper down there and so the next thing we're going
