Waterford were one point short of Galway in their penultimate Camogie League group game.
Beth Carton top scored with 8 points, while goalkeeper Brianna O Regan chipped in with two long-range frees.
It ended 0.13 to 0.12 with Waterford trailing 10 points to four after the break.
The second half was all Waterford as they outscored their hosts eight points to three.
They go again this weekend when they face Kilkenny in the final group game.
