Water Use in the Bathroom
 
 

Older toilets (installed prior to 1992) use 3.5 to 7 gallons of water per flush and as much as 20 gallons per person per day.

 
  Replacing an old toilet with a new model can save the typical household 7,900 to 21,700 gallons of water per year, cutting both your water and wastewater bills.  
  An average of 20% of toilets leak.  
 
 
  Tips  
Install an ultra low-flow toilet that requires only 1.6 gallons per flush.  
 
To ensure optimal performance, when installing a low-flow toilet in areas with a low drainage gradient (such as basements), consider a pressurized model.  
 
Check toilets periodically for leaks and repair them promptly.  
 
Reduce the amount of water used by an older toilet by placing a one gallon plastic jug of water, or two one quart bottles, in the tank to displace toilet flows. Or you can install a "dam" that partitions off a section of the tank so it can't fill with water. These methods can save over 1,000 gallons of water per person per year.  
  Don't use the toilet as a trash can.
