Hi, fixing a copper pipe to lead pipe involves a 'wiped joint'.
But how do you do a wiped joint properly?
thanks.

You are quite OK to do wiped lead joints for non-drinking water applications.
Forget leadloks - try the new Philmac universal coupling - far easier.
The following is a simplified description of joining lead to copper. It is somewhat of a skill which requires practice, and in reality is only done today in the chemical industry.
WIPED LEAD JOINT -
Clean inside the lead pipe and open up the end of the bore so it fits neatly over the 15mm copper pipe. Clean again with wire brush so it is bright.
Clean the outside of the copper pipe and apply flux (traditional paste flux) to both the inside of the lead pipe and the outside of the copper pipe.
Knock the copper pipe into the lead (the copper end needs to be turned over around the edge
Heat the whole area evenly then concentrate more on the copper, applying solder (leaded, lower melting point solder) to the joint.
Make sure the joint is full of solder and as much as it will take.
Clean off with wire wool.
no one has even mentioned cardwire and black or a turnpin or a shave hookHi, fixing a copper pipe to lead pipe involves a 'wiped joint'.

ive occasionally wiped in a bit of copper when changing a tank and no leadlocks in the van ive got no wiping kit any more but can get a reasonable finish with a bit of cardboard for a cloth and normal solder funny how a skill once learnt is never lost shame theres noi skills left in normal polumbing mowThe regulations state that no new lead may be introduced into potable water systems.
Therefore there is nothing to stop you putting one into a non-potable application if you really wanted to.
Never come across it in heating circuits but you may come across it in domestic hot water systems which are considered non-potable.

I still use a shave hook regularly for lead burning lead sheet. Going back even further, I remember bolt soldering joints at college in the early 80's.
I use a Philmac for lead pipes and on ocassion, I've even hammered one onto live mains!
When ever i work with lead i always cut it back as far as it can go and put a philmac adaptor on. You can get these from plumbcentre but you have to purchase separately the 15 or 22 copper adaptor . If youre unsure of the size snip a bit off and take it with you to the merchants and check the fitting will decrease in size to form a good seal. Do the job right or dont do it at all
thanks for the advice parkesy. Unfortunately the pipe is on show in the cloakroom so i dont want to put a plastic fitting on there really.
I wondered if it was possible to add some leaded solder to the joint in the same way you can add solder to a soldered joint .
Also is it legal to repair one of these as you would (if the repir is possible) be adding lead to a potable fitting? I'm guessing not.

In theory, is it possible to repair a lead to copper joint by heating and adding more solder?
I ask out of curiousity, I can find lots of info on making a wiped joint (thanks Fonta for the vid!) but non on repairing.
