Great Value Great Value, easy to read indicator light. I need a quick fix due to a water eater going out on a Friday evening. Didn't want to wait for Lowes to special order a unit and it take several days. This unit was in stock and provided a quick fix. if I had more time I may have gone with a larger unit. Though about going tank less but ad to many modifications t make for that to work. November 18, 2014
