Oh I don't have a house, I'm under 40 years old so that will likely never be possible, unless I win the lottery.

I have a studio apartment. The filter/tank is uh, i fill it up at the sink, holds 36 cups of water, gravity filter between the top resevoir and the main dispenser tank.

Benefit is the entire system is portable, and maintenance is very simple, the filters themselves are maybe $30 a pop, and the whole set up comes with a particulate detector mabob, so when it reads over a certain amount, filter is starting to go.

There is 0 chance the place I live can afford to overhaul the plumbing... they've been looking to sell the property for about a year now, lol, haven't found a buyer yet.
