I put mine on the kitchen sink. It has a four gallon holding tank and a di
unit that is installed on top of the sink. My family uses the di
faucet for clean drinking water. The four gallon tank fills up in about an hour or something like that. When it's full, it stops making water. When I want to make salt water, I drain that out into a bucket and an our later I drain it again, so I have eight gallons and so on. I make about 20 gallons of water every couple weeks and store the extra salt water in 1 gallon jugs. Then when I want to use that, I just pour it into a 5 gallon bucket and drop in a heater and powerhead to heat and oxygenate for awhile, than use it that way.
Oh yeah, never had any leaks. I set the whole thing up and then checked all the connections every day for a week as instructed in the manual, since then I've never noticed any leaks.
