In a medium saucepan, stir together the cheddar cheese soup, milk and water until smooth.
Bring to a boil over medium heat, stirring often.
Stir in the uncooked macaroni and reduce the heat to low. Simmer, stirring often so the pasta doesn't stick, until the macaroni is tender and the sauce is creamy, about 15 minutes. Add a splash more milk or water if it gets too thick.
Let stand for 2 minutes to thicken, then serve warm.
