Re-heating solder joint

[mdshaw]

I have 2x22mm pipes coming up through the floor with solder jointed right angle bends. They used to feed the bath which I have removed and will replace with a shower. I need to rotate them 90 degrees so they can feed through the wall- can I heat them up with a blow torch and rotate them or will they need to be removed and replaced with fresh ones?

remove and replace- can't guarantee a small amount of water ruining the joint.

Not a good idea, better off cutting out and replacing as said above.

If you only have a little DIY torch unlikely that you would be able
to keep a 22mm hot enough to move it anyway.

Give it a go it can only go wrong.

yes, heat it until the existing solder bubbles, rotate with grips, brush flux on the join, add a touch more solder then brush with flux again as it cools
