Leaking CH drain

You may regret doing so. But if you must, you need a blow torch , preferably MAPP gas ,and whilst heating the fitting would need to keep the other fittings right next to it cool ,or you would decsolder those too. You then need to solder in a short piece of pipe and cap .
Much easier to sort out the draincock !!
Understood. Just got back with the new one so will try now
