Pipe at 90deg elbow won't budge!!
 
2 Attachment(s)
I am trying to remove some galvanized steel pipe in my house and replace with PEX. There is an area where I have a 3/4 inch steel pipe that meets another 3/4 inch steel pipe at a 90deg elbow. I am trying to remove the one and start the PEX from there; however, the pipe won't budge! I disconnected the other end, and tried to move it with a pipe wrench which did not work. I tried oil, then vinegar, then a blow torch, and still it won't move one bit. What can I do to get the one pipe out?

Heat the 90 with a good torch and crank on it with a good ol 24" pipewrench.
Once you get it lose you might as well remove the 90 from the other pipe and reseal it while youre at it :)

Try this
 
Hi,Take your pipe wrench and tighten it in the area to get the most leverage .Then take a 3 or 4 foot piece of metal pipe the diameter has to be big enough to fit over the handle of the pipe wrench.Then slide the pipe over the handle of the wrench,then try to loosen the joint .The pipe will allow you to get alot more leverage and should loosen the joint .Good luck ,let me know how you make out
Thanks for your time

Why not just cut it out with a sawsall and replace all of it instead of just making a connection there?
That cracked us up, oil and vinager, what were you planing on making a salad? That will do nothing to loosen it up.
A longer pipe wrench will get it disconnected.

If you need to save the threads on the pipe, either a hack saw or sawsall and cut the elbow in line with the pipe just short of the threads on the pipe spread cut with screw driver blade and it willl turn off. Large elbow cut both sides of elbow.

Drain the water out- heat the 90. Put some big pipe wrenches on it, and cuss like a plumber--good luck

I will try again with the pipe wrench, but I am not sure I will get anywhere. I think there is a lot of mineral build-up in there that is not helping things (plus it is at least 50 years old). I have some more questions about cutting. Would I be cutting the 90deg joint or the pipe I want to replace? Once I cut (either) how would that help me remove what is needed to make the connection?

PS - The vinegar removed the buildup outside near the joint and the oil applied later to loosen the joint. It was not together and not like a salad dressing...

Time wise you are money ahead if you can't get it loose within 20 min's

I'm a little confused on what you are expecting to spin off if you haven't cut anything yet.



:huh:

Something has to be cut, otherwise nothing will spin.

I'm wondering that too. If you look at the pictures, I get the impression that there's 2 90's with an vertical offset he's trying to spin out :huh: May one picture is upside down...

I was clued in when he started asking questions about cutting. It appears by that post that nothing has been cut, in which case trying to spin that piece out is completely futile, no matter what flavor of salad dressing you dump on it.

Hi All,

I tried again and no luck :mad:

Here is another pictures. I am 180 lbs and I was literally hanging from both pipe wrenches and it did not move in the slightest. The cut is a ways down, so that is why you cannot see it. You should be able to in this pictures.

Let me know what you think.

Thanks!

Note: The picture is on it's side. The brown wood is the ceiling.

Alan 02-25-2012 12:37 PM

Can you grab onto the pipe that's cut and try to leverage against that to make one of the other joints loosen up?

:huh:

Edit :

Your pipe wrenches are kinda far apart.

You get the most leverage by putting them right next to one another.

You get more leverage by decreasing the angle between the pipe wrenches. Start with a really small angle between them in order to break the threads. Once it starts turning you can increase the angle to get more rotation for each "bite" with the wrench.
