Shower
Showers are responsible for using 37 percent of a home's hot water. The next biggest culprit, the washing machine, uses 26 percent.
People use over 50 gallons a day at just the sink and shower.
Older shower heads use 4 to 6 gallons per minute (GPM). Any shower head made after 1994 can have a maximum flow rate of 2.5 gallons per minute. Low flow shower heads use only 1 to 2.5 gallons per minute, which means up to 83 percent savings on your hot water usage.
At the sink, a regular faucet can use 3 to 4 gallons per minute, while those made after 1994 use 2.2 gpm. A faucet aerator can reduce this down to .5 gpm.
Ways to help improve the amount of water used by your shower and sink include low flow shower heads and aerators for your sink faucet. There are models out there now that use air to produce a shower jet as strong as a normal shower head or faucet while saving a ton of water.
Other ways to help include fixing leaky sinks - which can waste up to 30 gallons a month.
Don't let the sink run while brushing your teeth or shaving.
Take fewer baths - a typical bath uses 20 gallons while a typical shower only uses 14 gallons or less.
Don't stay in the shower for too long. An 8 minute shower is normal, anything over 10 minutes wastes water. If you trim your shower from 10 to 8 minutes in a month you can save up to 300 gallons.
