Here's how to quickly determine the flow rate for a specific faucet or shower head:
1. Turn the fixture on to its normal position.
2. Place a container under the fixture and collect the water for 10 seconds.
3. Measure the quantity of water in the container and convert the measurement to gallons (e.g., 0.25 gallons)
4. Multiply the measured quantity of water by 6 to calculate the flow rate in gallons per minute (0.25 gal x 6 = 1.5 GPM).
5. Remember: 8 Ounces per cup - 4 Cups per Quart - 4 Quarts per Gallon
Here's how to quickly determine the flow rate for a toilet:
1. The flush volume of your toilet is usually printed on the inside of the tank, on a tank label, on the back of the bowl,
or located on the actual flush valve. It is usually represented as GPF (Gals per flush) / LPF (Liters per flush)
2. All toilets purchased after 1994 were required to be 1.6 gallons per flush.
3. Toilets purchased between 1980 and 1992 were required to be 3.5 gallons per flush.
4. If your toilet was purchased prior to 1978 it could likely exceed 5 gallons per flush.
5. If your toilet does not indicate clearly the GPF rate, you may use the same procedure as the Irrigation Calculator
to find this rate. Just enter the same required reads below for the Starting and Ending Meter Reads

Gallons Per Fush
The Mid Penisula Water District has a rebate program for qualifying toilet replacements.
Here's how to read your water meter for these tests:
Your meter reads in cubic feet.
The numbers around the face of the dial are equal to one tenth of a cubic foot.
Each full rotation of the red needle represents 1 cubic foot.
This will change the white numbers with the black background in the register by one number.
These white numbers represent one tenth, and one hundreth of a whole "unit".
The black numbers with white backgrounds are whole "units" or hundred cubic feet.
100 cubic feet or 1 "unit" of water is actually 748 gallons.
Here's how to quickly determine flow rate for a specific watering station:
1. Turn off all water use in the home and remove the cover to your water meter box.
2. Note the starting read on your water meter including the needle position.
3. Manually turn on the first watering station. Run for 1 minute. After 1 minute, shut off first station, re-read the meter
and note the end read. These are the reads you will enter below to determine the irrigation totals.
2. Repeat this process for each watering station. After the last station has been entered you will need to
enter the preset runtime that each station normally operates if you use an automatic timer.
