Identifying first and second reservoir statuses

An example device in accordance with an aspect of the present disclosure includes a first reservoir for a printable composition, a pump fluidically coupled to the first reservoir and a second reservoir, and a valve to prevent backflow from the second reservoir to the pump. The valve is to selectively isolate the second reservoir from the pump based on a threshold pump pressure under which the valve is to close.
