tubería
/tubeˈɾia/ · B2 · noun · f
tube
🚰 tubería = tubo (tube) + -ería (a set of): all the tubes together
Spanish -ería often means a collection or a whole system, the way ganadería means livestock in general. Tubo comes from Latin tubus, which also gave English tube. So tubería is the full set of tubes: the piping.
