The Hancock Shaker Village, in Massachusetts, is one example of America's many Utopian communities. Photograph by Polly M. Rettig, Landmark Review Project, 1974.

There were hundreds of communal utopian experiments in the early United States, and the Shakers alone founded around 20 settlements.

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.
If your furnace fails to turn on, there are some simple things you can do to check out whether the thermostat is bad. The test procedure is the same for natural gas, oil, and propane furnace thermostats.. Remove the thermostat cover to expose the inner workings and blow or brush any accumulated dust out of the thermostat. Sometimes, dust build-up interferes with correct operation of a thermostat. On most thermostats, you unclip or snap off the cover without using any tools.
