Hey I'm new to my RO/DI should I drain it after every use? and if so how is that normally done?

do not drain it. The membrain must stay wet or it will spoil. I cap the lines with 90 deg. quick Quest fittings. One end of the fitting has a small peice of tubing that I melted and sealed. Or you can tie all the lines above the highest point of the unit. Next time you use it just run it for 5 min. or so to flush out the water that has been standing in the unit.
