Jim and his wife Brigitte came after lunch, and Jim made short work of the connections to the existing plumbing that had been giving me trouble. His sweated joints may not be the most beautiful, but they held the first time we tried turning on the water. Which is a lot more than I can say for an annoyingly large percentage of the joints I've sweated.
Below are some more pictures of the progress so far.
And for good measure, here's a picture of my neighbor Cynthia's (she helped during the concrete pour) cat Fritz. He was waiting in our driveway for some attention when I went next door to take the picture from above.
