About 75 percent of the water in the home is used in the bathroom. Put these conservation tips to work.

Showers usually use less water than tub baths. Do this the next time you shower: Plug the drain and compare the water level with the level you would use for a tub bath. This will give you a good idea as to how much water you save with a shower.

Install a showerhead that restricts the amount of flow. You can reduce the amount of water used from about five gallons per minute to approximately two-and-a-half gallons per minute and the new, or modified, shower head will pay for itself in a short time.

Take shorter showers. Turn the water off while soaping and back on again only to rinse.

Don't use hot water when cold will do. Save water and energy by washing hands with soap and cold water; add hot water only when hands are especially dirty.

If you have no shower and must take tub baths, reduce the level of the water you have been using by one or two inches.

When brushing your teeth, turn off the water until you need to rinse your mouth.

Even when washing hands, don't let the water run. Wet hands, turn off the water while soaping and scrubbing, and turn it on again to rinse.

Shampoo your hair in the shower. It takes little more water than for the bath, and much less than a separate shampoo will use.

When shaving, pond hot water in the basin instead of letting the faucet run.

Your commode could be leaking without your knowing it. Do this: Add a few drops of food coloring to the water in the tank, but do not flush. Now watch to see if the color appears in the bowl within a few minutes. If it does, the fixture needs adjustment or repair.

Weight two one-quart plastic bottles with stones or fill with water and replace caps, and lower them into the tank of the commode. This will reduce the amount of water in the tank but still provide enough for flushing. (Bricks, which some people use for this purpose, are not recommended since they crumble eventually and could damage the working mechanism, necessitating a call to the plumber.)

Install faucet aerators to cut water consumption.

Never use the commode to dispose of cleansing tissues, cigarette butts or other trash. This can waste a great deal of water and also places an unnecessary load on your sewage treatment plant.
