Yechiel Michel Epstein,
Translation:Arukh ha-Shulchan…
“ We have already written that the head of the household does not dilute the wine for himself, rather having another perform this service, so as to display his free state. We, however, are not particular in this practice, for it appears arrogant for a man to order his wife to dilute this cup, as he is no better than she. ”
