ADH or vasopressin controls water reabsorption in the distal and collecting tubules by stimulating the insertion of aquaporin-2 channels into their luminal membranes. This allows for the movement of water from the tubules back into the bloodstream, leading to concentrated urine. Water reabsorption in the proximal and loop of Henle are regulated by other factors.
