ALWAYS ON THE LOOKOUT for something we’ve never seen before, I was ecstatic to find this “Tappan Ultraflo push-button plumbing” innovation. It was featured in a copy of Popular Mechanics (Sept. 1963) that I picked up at Ron’s place last week. According to the story, mysterious unseen solenoids mix the temp magically so you never have to bother with those, what are they called again…oh yeah, faucet handles. This could be installed in the bathroom, too. Click through to see the groovy wiring diagram and full text.
