Bathroom - Toilets

• Install a new toilet which uses 1.28 gallons or less of water per flush rather than 3.5 - 8 gallons per flush (all toilets available after 1992 are 1.6 gallons per flush or less).
  
• Replace your toilet tank flapper every year or two. A flapper leak is the most common yet undetected leak you’ll find. Make sure you buy a flapper that is designed to fit your toilet make and model.You could save 1,000 gallons each month.

Bathroom - Showers

• Install a new showerhead to reduce water use by 50% or more. You'll save about 1,000 gallons in one month.
  
• 3 gallons per minute per shower.  For showers in bathtubs: the shower diverter valve is a common source of water loss.  If this valve leaks, you will see water leaving the bathtub faucet when you are showering.  This fix may require a plumber, but will save you on your water and natural gas bill.
• If you take a five-minute shower instead of a bath, you save about 15 gallons per shower.

Bathroom - Faucets

• Install a faucet aerator (flow restrictor) on the faucet.
• Or replace older models and save 2.5 gallons per minute per person.
• Turn of the faucet while brushing your teeth and shaving.

Kitchen - Faucets

• Install an aerator (flow restrictor) on the faucet.
• Replace any model kitchen faucet (prior to 1992) with a new model.  That change can save up to 2.5 gallons per minute of use.
• Fill the sink basin with water instead of constantly running water to wash dishes.

Kitchen - Dishwasher

• If you use an automatic dishwasher, wait until you have a full load. You'll save 10-12 gallons for each cycle avoided.
