Some new homes and apartments already have low flow shower heads, and some plumbing codes require them. But most of us have "high flow" shower head that gush water at 5-10 gallons per minute depending on water pressure by installing a low flow shower head you can reduce your usage to a little as 2.4 gallons a minute.
On average faucets use 5 gallons of water per minute of use. An easy to install, inexpensive faucet aerator can cut usage in half.
When a toilet leaks, water escapes from the tank into the bowl and washes away into a sewer. Toilets are notorious for hidden leaks, because unless the toilet "runs" after each flush (which can waste 4-5 gallons a minute) we seldom notice them. A silent leak caused by a corroded flush valve can waste about 10 gallons of water an hour - money down the drain that you can't see or hear. (Remember for every unit of water you use, you are charged for a unit of sewer usage as well.) | |||
