Tinning steps

[shd1970]

I have used a Yorkshire elbow in a tight spot and it has failed so i need to redo.
I have removed the elbow but obviously the pipe ends still have solder on them.
So i presume the ends are both classed as being "tinned", yes ?
If so, what's the the steps to try another elbow, just clean with wirewool the pipe ends and the inside of the elbow, flux both pipes and inside of elbow as normal ?
Also, can i use another Yorkshire ?

Heat up the tinned ends wipe off excess solder with a rag (mind your fingers) as long as no blobs of solder remain the solder ring fitting should fit on OK. Just clean up pipe and fitting as normal and away you go.
Do you know why the joint failed?
Worth investing to ensure clean fittings. https://www.toolstation.com/shop/p4...MIgNDj8_X72wIVTb7tCh1EdgTMEAQYASABEgI21vD_BwE

Thanks for the reply footprints.

Just cleaned up and tried again but the one end sprung off and it was the end that goes to my new outside tap (wall thickness away) which has a check valve.
Don't see why it could as it's "outbound" direction but could that be the reason ?
Outside tap is open btw

Confused as gotta repeat....Not happy

Are you draining the pipe fully, if there is even a tiny bit the joint will not form correctly, sounds like you are boiling the water and steam is pushing the joint apart.

Stick a bit of bread in the pipe and try again.

Sorted it....Pipe was empty all but for a dribble but just opening the tap was no good....Took the outside tap off completely and my tinned joint worked first time so it was pressure that pushed the joint apart

Joint tested and all good

Thanks for input once again

It's quite a common problem with end feed caps as well... If there's nowhere for the heat to go, the caps want to pop off.
