Hi, Newbie here. I just put together my first RO/DI unit (Coral Life Pure Flo II 4 Stage). The flow seems ok and for now it seems like its on target with its 50 gal/day output. There is a hissing sound that comes from the end of the membrane chamber on top. No leaks. Can anyone let me know if this is normal? Thanks!
