[ULPIANUS libro uicensimo nono ad Sabinum. ] §18.1.49.pret quamquam ius aquae non sequatur, quod amissum est, attamen fistulae et canales dum sibi sequuntur, quasi pars aedium ad emptorem perueniunt.
[ULPIANUS, On Sabinus, Book XXIX] And although the water right does not follow, because it has been lost, nevertheless, the pipes and channels, so long as they remain connected to each other, pass to the buyer as if they were part of the building.
et ita Pomponius libro decimo putat.
And Pomponius thinks so in his tenth book.
