Step 3RESULTS!
Well first off I took a shower after doing all this, and there is a difference but it's not that noticeable
Height before = 3' 8" from the rim of my tub
Height After = 3' 3" from the rim of my tub
Rate before = 1cup / 1.795second * 60 Seconds / 16 cups = 2.089 Gpm
Rate AFTER= 1cup/ 2.535 seconds * 60 seconds / 16 cups = 1.4822 Gpm
Basiclly you take the time it takes to fill 1 cup, multiply that by 60 seconds to get the time in minutes, and divide by 16 cups to get it in gallons.
Total water used for 15 minute shower:
Before = 32.325
AFTER = 22.233
So your saving 10.092 gallons for every 15 minutes you shower, and in a house like mine where there are 10 people it works out like this.
10.092 * 10people * 30 days = 3027.6 gallons saved
3027.6 * .003 cents/gallon = $9.08 / month * 12months = $108.99 per year =)
Not bad for a piece of plastic you were about to throw out eh?

I recently installed a low(er) flow shower head and used a stock pot that has markings on the side to measure the old and new heads. The old 2.5 GPM head put out 7 quarts in 30 seconds (yep, that's 3.5 GPM) and the new Niagara 1.5 GPM head put out 3.5 quarts in 30 seconds (1.75 GPM). I guess the ratings for these things are just rough estimates. ;-) Still, I like the new shower head. It works very well, the spray is not uncomfortable at all and it saves money because I cut the flow in half.
