Beware! sometimes the new tap tails (threaded part) are shorter than the old and if the copper feeds are really rigid you can't 'stretch' them enough to reach the new tap (so near yet so far 😡). End up cutting back the 1/2" copper feeds and extending just for that extra 10-15mm....🙁
Yes, that is with old taps from before about 1970, which had longer tails.
