Believe us, we really wanted to make the Nebia by Moen Wand work independently of the Overhead. We couldn’t include that feature for regulatory reasons, which are designed to protect people from scalding. The flow rate of the Wand is about 0.4 gpm, whereas the flow rate of the Rainshower is about 1.35 gpm. For many shower valves, when the flow rate suddenly switches from 1.75 gpm to 0.4 gpm, the temperature can also suddenly increase, which creates a potential for scalding. While we don’t think there is much risk of scalding for this product, we had to stay in compliance with these rules. We fully understand the many reasons why you would want to use the Wand without the Rainshower. We’re working on delivering this feature, completely safely, in future products.
