            a  Leak  Week  Student Worksheet
Learn how to find leaks and save water at home during Fix a Leak Week

Lesson 1: Watch the Clock (and the Meter)
What's the big deal with drips? Small leaks can add to big water waste. Try these activities and math
problems to see how fast water waste adds up.

Activity: Check Your Water Meter
Water utilities, the companies or organizations that provide running water to our
homes, keep track of how much water a family uses each month or season with a
water meter. Your home's water meter is a device that measures how much water
flows into your house. Water meters are usually located outside, either under a
metal cover on the sidewalk or in a box outside the house.
See the example of a water meter to the right. The numbers in the boxes show
how much water has been used since the last reading. Meters show water use in either
gallons or cubic feet (or ccf, a hundred cubic feet). 1 cubic foot of water = 7.48 gallons.
One way to discover if your home has leaks is to check your water meter before and after a two-hour period
when no water is being used. Here's how: Check the meter and write down what it says. Then be careful
not to flush the toilet, run the faucet, or use any water for at least two hours. At the end of two hours, check
the water meter again. If the meter does not read exactly the same, you probably have a leak. Note: If your
water meter is in cubic feet, the leak may not register within two hours unless it's a very large leak.

   Where is the water meter located at your house? 	
   What unit of measure does your water meter use? (Circle one)   Gallons   or   Cubic Feet

Instructions:
1.  Find the water meter for your house. Write the number and unit it says here: 	
2.  Wait at least two hours. Be careful not to use any water. That means no toilet flushing, dish washing,
   clothes washing, hand washing, showering, bathing, or running the hose for the next two hours.
3.  At the end of two hours, go back to the water meter to see if it has changed. If it has changed at all,
   you probably have a leak.
   Write the number and unit it says here: 	
Bonus: If your water meter reading is in cubic feet, convert it to gal-
lons. Or, if your water meter reading is in gallons, convert it to cubic
feet. Use the equation to the right. Use the final water meter reading
for this exercise.
   Write the conversion here:
Conversion Equation
Cubic Feet to Gallons
1 cubic foot = 7.48 gallons
100 cubic feet = 748 gallons

Lesson 2: Be a Leak Detective
Some leaks are harder to find than others. They can be sneaky and silent, and you have to be a sleuth to
detect them. Here is an experiment to help you track them down.

Activity: Check for Toilet Leaks
For this activity you will need:
  •  Food coloring or dye tablets
  •  A clock or watch
  •  A helpful grown-up
  •  A toilet

Instructions:
  1. Remove the lid off the toilet tank. (Ask an adult for help—the lid can be heavy and hard to move.]
  2. Add a few drops of food coloring or a dye tablet into the tank. Do not flush the toilet.
  3. Wait 15 minutes. If color appears in the toilet bowl without flushing, it has a leak.
  4. Flush the toilet immediately after the experiment ends to avoid staining inside of the tank.

Do the Math:
  A constantly running toilet can waste more than 200 gallons of water every day. How many
  gallons will the leaking toilet waste in a week (7 days)?

  Write your answer here:
                              gallons
   Bonus: How many 8-ounce glasses of water could
   you fill with the amount of water saved from fixing
   the leaking toilet?

                              gallons
                                                              fluid ounces
                                                              glasses of water

         Lesson 3: Do a Drip Scavenger Hunt
         While toilet leaks are usually the biggest water wasters, even small drips from a faucet can add up.

         Activity: Check for Dripping Faucets, Showers, Pipes, and Hoses
         For this activity you will need:
             A watch or clock with a second hand
Instructions:
  1. Walk through your whole house, looking and
    listening as you go from room to room. Use the list
    at right as a guide on where to check for drips.
  2. Check the appropriate checkbox if you find a drip
    or leak.
  3. If you find a drip, use your watch to measure how
    many times it drips in one minute. If you find a pipe
    that isn't dripping, but is wet, write that down too.

Do the Math:
Location of Drip Drips per Minute
Bathroom(s)
Faucet Q
Showers Q
Bathtub Q
Kitchen

Pipes under sink Q

  gallons of water does it waste in 1 year?
