One thing that concerns me about the total drain tank is it appears the bottom of the tank is resting on the MDF. On the US plastics website most of their tanks that do not have a flat bottom are supported on the rim of the tank.

I choose to support my tank by making a box were support is applied to the rim of the tank. The bottom of the tank does not touch the self.
I was going to valve down the R.O. unit however, Spectra Pure advised me the unit was not meant to operate in that manner. Not a big deal since I only need to make water once every two-weeks.
Again nice looking system
