Young Blonde Girl Strips In The Shower

A shower head is a perforated nozzle that distributes the water over a large solid angle at point of use, generally overhead of the bather. Thus less water than full immersion can be used to wet the same area. All residential and most commercial shower heads sold in the USA must flow less than or equal to 9.5 liters per minute (2.5 gallons per minute) per the Department of Energy ruling 10 CFR 430. Low flow shower heads, less than or equal 7.6 liters per minute (2.0 gallon per minute), can use water more efficiently by aerating the water stream, altering nozzles through advanced flow principles or by high speed oscillation of the spray stream. USEPA administrates a voluntary water saving program WaterSense, which can certify low flow shower heads. Some shower heads can be adjusted to spray different patterns of water, such as massage, gentle spray, strong spray, and intermittent pulse or combination modes. Hard water may result in calcium and magnesium deposits clogging the head, reducing the flow and changing the spray pattern. For descaling, various acidic chemicals or brushes can be used or some heads have rubber-like jets that can be manually descaled. A homemade remedy is to immerse it in a solution of water and vinegar for a while, since the vinegar is able to dissolve limescale.
In contrast to the USA, luxury/therapeutic showers that use over 40 litres of water per minute are sold worldwide and are increasingly common as the world population ages and people's disposable income increases.
