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