Yep, I ordered the filter kit with it; it comes with a 10 micron cold water filter and 5 micron hot water filter. I'll consult with the plumber, but there's no hurry since my D250 isn't expected to ship until Mar 12. It should be a relatively straightforward installation. The gravity drain makes me a little nervious though since there's a washer on the same drain, and it's not gravity! The thing has an outlet pump; if the drain pipe backs up I'm concerned it might back up into the ATL before the washer notices and stops. So I need to have the plumber suggest something, perhaps a one-way valve of some sort. Or a manual valve that can be closed when the washer is in use.
I'd hate to find my processor blowing bubbles.
