Most handles in homes are fastened to the valve shafts with screws, but on many commercial and industrial applications they are fitted with a removable key called a "loose key", "water key", or "sillcock key", which has a square peg and a square-ended key to turn off and on the water; the "loose key" can be removed to prevent vandals from turning on the water.Before the "loose key" was invented it was common for some landlords or caretakers to take off the handle of a tap, which had teeth that would meet up with the gears on the valve shaft. This tooth and cog system is still used on most modern taps. "Loose keys" may also be found outside homes to prevent passers-by from using them.
Shower usage in the latter half of the 20th century skyrocketed. Personal hygiene became a primary concern, and bathing every day or multiple times a day is common among Western cultures.Showering is generally faster than bathing and can use less water. In an average home, showers are typically the third largest water use after toilets and clothes washers. The average American shower uses 17.2 gallons (65.1 liters) and lasts for 8.2 minutes at average flow rate of 2.1 gallons per minute (gpm) (7.9 lpm). Showering is one of the leading ways we use water in the home, accounting for nearly 17 percent of residential indoor water use, roughly equals to 1.2 trillion gallons of water annually just for showering.The U.S. Environmental Protection Agency recommend to retrofit home showers with a shower head that uses less than 2.0 gallons per minute to conserve water. However, many have hypothesized reducing flow rates of showerheads might cause users to take much longer showers. Other options to save water include using extra high pressure mist flow or design in sensors and valves to shut off or reduce water flow while people are not actively using the shower water.
A shower is a place in which a person bathes under a spray of typically warm or hot water. Indoors, there is a drain in the floor. Most showers have temperature, spray pressure and adjustable showerhead nozzle. The simplest showers have a swivelling nozzle aiming down on the user, while more complex showers have a showerhead connected to a hose that has a mounting bracket. This allows the showerer to hold the showerhead by hand to spray the water at different parts of their body. A shower can be installed in a small shower stall or bathtub with a plastic shower curtain or door. Showering is common in Western culture due to the efficiency of using it compared with a bathtub. Its use in hygiene is, therefore, common practice.A shower uses less water on average than a bath: 80 litres (18 imp gal; 21 US gal) for a shower compared with 150 litres (33 imp gal; 40 US gal) for a bath.
