These noises indicate the flush ball needs to be adjusted to stop wasting water. To reduce the amount of water used with each flush, fill a plastic, one-quart bottle with water and place in the toilet tank. To anchor the bottle, partially fill it with sand or any heavy substance. This does not affect the efficiency of most toilets and can save five or more gallons per day for a family of four. Avoid using your toilet for a wastebasket or ashtray.
Extra flushes cost money and the debris flushed down can cause expensive damage to the plumbing.
While shaving, partially fill the sink basin with water and clean the blade in this, rather than running a steady stream. For brushing your teeth, run the water only long enough to wet your toothbrush and fill a cup for rinsing. Extra-long showers gobble up many gallons of water. Limit showers to five minutes. One trick is to turn off the water while washing hair and soaping up.
