This is our second unit, it seems like they used to have a 3 or 5 year warranty. Anyways, these units are great and very convenient. Once you have one, you'll wonder how you did without it. They work great, no issues typically.

Now for the downside, 5 years is about their maximum lifespan so plan on it. We had one when we built the house, it was replaced under warranty after about 2.5 years then a month ago (Feb 2016) that unit failed after 5 years. After some research, it appears 5 years is about their lifespan. When they fail, they begin leaking which I consider a design defect. The leaking occurs inside the housing, not the connections. Look on Youtube for some videos.
