Thank you for your kind compliments. Sorry to hear about your old lead pipes. I have heard that when they are old, they could become quite furred up with limescale and it might help to protect you, if it is true (that is while going round Pompei years ago). However, I expect there is lead in your tap water. The amphora is very good at reducing levels of heavy metals. Lead, Arsenic and Mercury were reduced to 1/10th of their original value after an 8 hour cycle in the amphora. You could also try leaving the tap water in the amphora for 12 hours, so you get two cycles a day to acheive further reductions.
