How to remove pipe fittings from unstable pipes?

How should I secure it to be able to apply some torque? Please don't laugh. Thanks!

Edit: I think I just got it. A pipe wrench! Let's see....

 

A pipe wrench or adjustable wrench.

 

If you put a large visegrips onto the body, you will have something to hold onto while you use a wrench to loosen your parts.

 

Okay, I'm back up to speed. I'd forgotten how I'd done this a couple times before but now I'm here:

As u can see I've got this shark bite thing that is supposed to remove these ferrules. Will it? Just watched a couple of videos that made it seem easy but I'm not moving anything with this tool. What's the trick here? The ferrule isn't exposed in the back so I can't push directly on it but the nut itself yes. Maybe I can't use the tool like this? Thanks so far...

 

I don't think that is a shark bite fitting.

 

That does not look like a shark bite fitting to me,more like a compression fitting there. Might have to cut it off.

 

Oh, I thought that orange tool I have is supposed to remove that ferrule.

This is insane. Why couldn't this have been a nice easy job? I'm having to cut underneath this faucet part with one of these multi cutting tools because the nuts underneath are rusted. If I have to replace the whole sink I'll have to remove the garbage disposal and this will take longer.

Anyone know how I can temporarily cover the pipes below while I work on this and still have water? Are there temporary covers or something? I'm only familiar with one shutoff valve outside for the whole house.

 

They have compression fitting shut off valves. All you have to do it take old one off. Nut should loosen with a sharp tap with a hammer on wrench. Be sure you are holding old valve before you tap wrench. Here are some valves.

Thank u. Silly me. I already have my valves but it just didn't occur to me I could install them by themselves and they could cut off the water. But I got the faucet off and just need to drill a hole in the sink for the veggie sprayer. I should probably buff the area I ruined.

Are these compression valves easy to install? I did it once a while back. Don't remember if it was easy? I know sawing off those old ferrules won't be!

 

Compression valves are a standard size meaning that your existing nut and ferrule should work with a new same size valve.

At the very least.... the new valves come with a ferrule and nut if you did have to replace them.

You would cut the pipe cleanly just behind the ferrule. Trying to cut a ferrule off usually damages the pipe and a new ferrule won't seal properly.

 

K thanks. I'll just leave them then. Just screw them on? Do I need to do anything to set the ferrule right or something? Can you screw this part up?

I have a tendency to mess things up.

 

Just slip the valve on the pipe. Be careful not to cross thread nut.
