Help with a seized up pipe (Used a patch fix that seems to be holding up well)

I didn't feel like fooling with replacing the whole thing right now and decided to try a patch fix to hold it over to the weekend. The risk of it causing damage it extremely low because it is in a detached garage. I removed the handle and top nut to expose the shaft where the leak was coming from. I wrapped several layers of plumbers sealant tape around the bottom of the shaft and the threads. Reinstalled the nut and handle and sure enough no leak. hopefully it will hold till this weekend when I have more time to fool with it.








This is related to the water shut off valve I created yesterday. Water will shoot out the top of the valve whenever I turned it. Thought simple enough get a new valve and replace it. Well I can’t get this thing off to save my life, any ideas?

Krol and a torch? If the pipe is copper past the fitting, could save you a headache and just cut it lower and either sweat a new slip coupling or pex adapt it with a new valve.

What tool are you using, if using Chanel locks, get a heavy pipe wrench

Two in opposition might keep from breaking it off in the wrong place. One on fitting and other on iron pipe.

Valve? No, cut that whole nasty setup out and put in a new one. Galvanized couplings? Something called galvanic corrosion you are about to become very familiar with.

start over, a whole new box with 2 new valves only costs like $20 at home depot LINK

if you are fixing it, then fix it the right way

As close as I zoom in-it looks like copper under the galvanized coupling? Do as others have suggested and cut the line below the galvanized coupling out and replace entire box. Whenever you join copper and galvanized piping-you MUST use a dielectric union between the 2 or corrosion of the piping will take place resulting in an unexpected disaster.

Looks like brass to me.

I hear a'll about copper to galvanized but brass to either has been a go... and is aok.
