The Hancock Shaker Village, in Massachusetts, is one example of America's many Utopian communities. Photograph by Polly M. Rettig, Landmark Review Project, 1974. The Amana Colonies were one of many utopian colonies established on American soil during the 18th and 19th centuries. There were hundreds of communal utopian experiments in the early United States, and the Shakers alone founded around 20 settlements. While great differences existed between the various utopian communities or colonies, each society shared a common bond in a vision of communal living in a utopian society.
Thermostatic Mixer Valves must shut down completely if the cold water supply is interrupted. This is called a fail safe. Hot water temperatures are often used to control the growth of legionella bacteria. This can lead to a risk of scalding.
When the gasket fails, coolant comes out of what is called a weep hole. If you don't replace the water pump, the bearing gets saturated with coolant and fails. When the bearing fails, the water pump pulley ceases and the belt fails. I have seen this too many times. That fan thing is called an impeller and when it spins it pumps coolant through the motor and radiator to keep it cool.
