First, find a home for your new water wizard. Basements, garages, or utility closets are perfect—somewhere dry, not too cold, and close to your main water line.
You’ll also need a drain nearby for the “reject water” (the bad stuff the system flushes out). Don’t worry, it’s not gross—it’s just the water that did the dirty work so you don’t have to.
Pro tip: Avoid places where your cat likes to nap. They’ll judge you every time you work on it. True story—mine tried to “help” by sitting on the instructions.
