Apparently in 1963, turning the handles of a faucet was a labor most terrible and unbecoming to the forward-thinking homemaker. To eradicate this scourge, Tappan created the Ultraflo plumbing system. Citing Popular Mechanics magazine, its panel of push-buttons delivered water without the tedious 'waiting...to reach the desired temperature [or] trial-and-error manipulation of the faucets.'Thank goodness.
