There actually quite easy to hook up. I have mine under the bathroom sink so it can easily drain into the tub. Others place them in the laundry room for the same reason. If in the kitchen, you would need to drill a hole in the drain pipe. Easily done but keep in mind permanent. With well water I would also suggest a DI
cartridge. You can easily plumb the unit so the RO
is for drinking and the RO
for tank use.
I could only find a basic <<link>>
(.pdf) on the workings but if you shoot me an email (don't post it here), I can forward you the info from the company I purchased from. It gives a little better detail on the hook up "intricacies".
