According to standards set by the federal government, a low-flow showerhead uses no more than 2.5 gallons of water per minute at a water pressure of 80 pounds per square inch. That’s less than half the rate of water used by some older traditional showerhead models. Low-flow showerheads come in two main types, aerating, which creates a mist, or laminar-flow that sends water out in a steady stream.
Master plumber: To become a master plumber, a person must have a certain number of years' experience as a journeyman plumber, in addition to an associate's degree or training at a vocational school. A master plumber must pass an exam that typically encompasses both written and practical knowledge. They must also complete continuing education hours every year. Oftentimes the business owner, a master plumber is subject to inspection and must make sure all journeyman plumbers working for his or her company are in compliance with plumbing regulations.
Those who attempted to bring plumbing indoors faced technical as well as attitudinal challenges. Decisions on how wastewater was removed required as much concern as those made to ensure an adequate water supply. But equally vexing was the prevailing miasma theory of disease, which held that illnesses stemmed from "bad air" that was readily identifiable by its offensive odor. This led to a distrust of early indoor plumbing that tended to leak and a deadly fear of the sewer gas that accompanied the leaks. It is no wonder then that many individuals maintained a strong belief that elimination was best taken care of out of doors.
