I am fairly certain that most of you do not have this contraption in your houses. Morgan spent a lot of hours on this sucker, a beautiful copper poem to all of the irritating plumbing jobs he has ever encountered. It allows us to control the water flow to the yard, to the house, to the spigots on the sides of the house, to the hot water heater. We can drain our system in various specific ways without going outside. There is a drain in the floor under the water heater that two pipes go right over, easy peasy. The valves all open in the same direction. It is a sculpture of right angles, symmetry, and flow. 
Now, on to the powder room!
