Hi Shawn, I am a bit confused by your reference to the Nano Wavebox (6206). The 6212 is the older big wavebox, where the 6215 is the new big wavebox. 6212 uses the Stream 1 pump, where the 6215 uses the Stream 2 pump. My understanding is that the box of the 6215 had to be modified from the 6212 design to accommodate the different shape/size of the Stream 2 pump. So I am wondering if there is a way I can get the Stream 2 pump into the 6212 box.
