Toly is awesome help, first and foremost he is NOT scared of spiders. Second, he can be counted on. He will go get things with incredible accuracy. We finished the hot water portion of the plumbing. This involved a re-circ line back to the water heater. This keeps warm water at the fixtures.
We also did some drainage plumbing, including the vent through the roof. This shows the under sink lines. There is a hot water supply for an instant 180° water dispenser--remember the dream kitchen thing?
Toly and Tristan learned how to sweat (solder) copper pipe.
