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.

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.

In such a case, the pressure valve should be adjusted while the toilet is making the noise.
Full Answer >To calculate the water flow rate through a given pipe size, multiply the area of the inner cross-section of the pipe by the velocity of the water. The velocity of the water is required for this calculation.
Full Answer >Multiply four by the volumetric flow rate to obtain a product. Then multiply the pipe diameter times itself and times pi to obtain a second product. Divide the first product by the second product and set this value equal to the velocity of the fluid to obtain the answer.
Full Answer >To calculate the water flow rate, square the pipe's diameter, and then multiply that number by pi, .25 and the velocity of the water flow. For example, a pipe with a diameter of 3 inches, or .25 feet, and a water velocity of 20 feet per minute yields a flow rate of approximately 0.98 cubic feet per minute. Convert this number to the unit of measure for residential flow rates to yield a final answer of 7.34 gallons per minute.
