EPA restrictions enacted in 1994 limit standard showerheads to a flow rate to 2.5 gallons per minute (gpm). This is not only to save water, but to save energy usage by the water heater. Previously, shower heads had a standard flow rate of 5.5 gpm.Know More
Showering accounts for 17 percent of indoor home water use. The United States uses 1.2 trillion gallons of water annually just for showers; this is enough to supply residents of New Jersey and New York with water for a year. Water-efficient showerheads save even more water by decreasing the flow rate to 2.0 gpm.
The EPA certified WaterSense label ensures that the spray intensity and water coverage is equal to that of standard 2.5-gpm showerheads. WaterSense showerheads save an average family up to 2,900 gallons of water per year. This not only saves money but decreases the demands on the water heater, giving it a longer life.
Replacing a standard showerhead is simple. The average homeowner can use an adjustable wrench to remove the old head. After removing the old plumber's tape, he can apply new tape in the same direction that the head is screwed on and then tightly screw on the new showerhead . Multi-jet shower towers often require a plumber for installation.Learn more about Plumbing
To calculate the flow rate in a cylindrical pipe, the basic formula, which is flow rate is equivalent to pipe cross-sectional area multiplied by velocity, can be used. Here the area is calculated as pi times pipe diameter squared and divided by four.Full Answer >
A flow switch is a mechanical gadget used to control the flow of liquid, air or steam. The switch works by sending a trip signal to another device in the system, such as a pump, to protect it from damage and for cooling circuit protection.Full Answer >
There are a number of reasons why a toilet may make noise after flushing; however, a loud noise that takes more than a minute after flushing the toilet may indicate a restricted water flow or a problem with water pressure. In such a case, the pressure valve should be adjusted while the toilet is making the noise.Full Answer >
Low-flow toilet models work as well or better than models that use up to seven gallons of water per flush. An evaluation program performed jointly between the U.S. and Canada proves how well low-flow toilets really work.Full Answer >
