Water prep.

[uboldig@rocketmail.com]

I'm thinking about making a cart with a sealed tank for changing the water in my tanks in the house. Im planing on having my Ro. unit directly feed the cart tank so I can batch mix larger amounts of water. Then have the heater, air aerator, and mixing pump connected by a float switch so I can let it fill and mix the salt wile I'm at work. does any body see any cons to this?
