Pipe angle fix

in THE MAIN WALL

1"pipe comes up wall and then 90 over to a horizontal approx 5ft long. Then, 90 up to radiator as shown.

This 5ft horizontal (run-out?) was slightly slanted down towards rad. I was able to lift rad some to get the pipe about level. Ideally, I would like it slanted away from rad some. It took quite a bit of force to lift it up to level so there is quite a bit of tension on this connection now.
How much can this pipe take before developing a leak? What else can I do?
This run-out is in between floors and I don't think I could take it apart if I had to...

    it can take quite a bot of force of everything is solid, if something is heavily corroded it could break fairly easily. is the problem yo are trying to solve going away? if you lift it a little at a time, like 1/4"-1/2" then give it a week or 2 to settle you might find it slowly adapts to the new position and is no longer under tension. i would do a little at a time and see if the problem goes away, do more if it doesn't. it isn't guaranteed to lift the section between floors vs lifting the whole riser and it could be up against some framing somewhere such that it won't lift at all.

    ultimately you could replace that nipple under the union with a shorter nipple and let the radiator sit back on the floor once you get the riser lifted enough.

    Is the bad horizontal pitch is below the floor ? You will need to lift the whole radiator .The incorrect pitch was created after original installation so all you will be doing is returning to original position . A good iron connection is tough to break …. How much do you have to raise ?

    There was an error rendering this rich post.

    Pulling up the floor or the ceiling below is the right fix. The fix is a swing joint. Forcing the pipe into position is not a great idea.

    That is why it's called pipe FITTING.

    The problem I am trying to fix is that radiator heats intermittently. Rad on same riser, 1 floor below heats just fine.

    Big Ed_4: It probably needs to be raised another half inch to an inch. It's level now.

    Swing joint, hmmm. If I could get it apart. I get at this from the drop ceiling space of the first floor. Would have to reach over the wall into large cavity to get pipe wrench on it.

    probably would have to cut a fitting off and come back with new pipe and fittings. if you have a suspended ceiling you have way more access than most.
