    As a plumber, for some 30 years' I'd prefer to solder. NOW, I have a good story about this, when doing building works for a famous chef, (living in Wandsworth, SW London), in the late 80's BUT, haha, I won't bore you!! 


    I had a plumbing engineer, as a good friend back then, and I told him NOT to use solder BUT... to use 'tallow' for joining the lead to copper, (obviously 'tinning' first), but he didn't do as I asked and just used solder and what happened, after he'd finished, (I was wiring industrial air con systems way down south near Worthing),  I was in BIG trouble as my client were going to a big BBC event, that night... they had some four bathrooms, plus a couple of toilets', and were left with ONE cold tap in the kitchen... after my 'friend' had left! I came home, late that night, and had a barrage of abuse, (from that chef), BUT... it wasn't MY fault. If only people would listen, NOT saying I'm always right but as Nigel Clough would say... "I'm not the best but I'm in the top 1.! Haha.


    I offered to go there, late that evening, but it was too late!!

    In my youth I watched a few joints/repairs being made in lead. They'd never ream out the lead pipe though - it was always flared out using a drift (no lead swarf left in the pipe that way) and the copper pipe would jam in solid so it didn't wobble when making the joint and allow solder into the main pipe. Cup joints were only ever used on low pressure pipes (e.g. gas or occasionally secondary water (after a cistern)) - never ever on a rising main - it would have been a full wiped joint for that.  They'd use some proper flux to wet the solder to not just a bit of old candle. If I recall correctly the old wiping pads were mole skin rather than bit of old fabric.

    You can use corderouy if you do not have mole skin -  it is  not such a popular fabric these days - I suspect if you ask for a 'moleskin patch cloth' at the plumbers merchant today the bored 20 something year old will be left wondering about animal rights - for those wondering its about as animal based as a Donkey Jacket, i.e. not at all.

    It needs to be thick enough not to let things soak through and hairy enough to give a good finish without too much drag. Tallow is essentially beef dripping, and yes, getting the oxide off and keeping it covered in a layer of fat so that it does not reform as an interstitial layer weakening the joint is key.
