Indoor Self-Audit

Indoor self-audits are easy to perform and will help you find ways to conserve water. Always fix leaks as soon as possible.

Self-Audit: Bathrooms

You can check your bathroom for leaks in 30 minutes with food coloring and a utility bucket.

Check the toilet.

  • Put a few drops of food coloring in the tank and wait 30 minutes to see if the color appears in the bowl. If it does, the toilet might have a leaking flapper valve. Flapper valves are easy to install and are available at most hardware stores.
  • Look at the back and bottom of the toilet for leaks on the supply line.

Check the sink.

  • Watch the faucet for a minute for drips.
  • Open the cabinet and check the hot and cold supply lines for weak spots, such as a bulge in the hose.
  • Turn on the faucets and watch the lines for leaks while they are in operation.

Check the bathtub and shower.

  • Operate the faucets to make sure they function properly.
  • Turn on the shower to check for leaks. When the water is diverted to the showerhead, the water flow from the tub faucet should stop.
  • It is difficult to check the exact flow from your aerators and showerheads without the proper flow bag (a plastic bag with measuring marks on the side). But if you have a utility bucket you know the capacity of, you can time filling it to determine the approximate flow.
  • If the showerhead and aerators have been on for a while, they might need to be changed. High-efficiency showerheads and aerators are available at any hardware store and are easy to install.

Self-Audit: Kitchen
