For approximately $10 to $20, the average homeowner can install two low-flow shower heads, install aerators on the faucets, and repair dripping faucets and leaking toilets. This could save 10,000 to more than 25,000 gallons per year for a family of four, and would pay for itself in less than a year!
Learn to repair faucets so that drips can be corrected promptly. It is easy to do, costs very little, and can mean a substantial savings in the plumbing and water bills.
Check all water-line connections and faucets for leaks. A slow drip can waste as much as 170 gallons of water EACH DAY, or 5,000 gallons per month, and will add to the water bill.
Insulate all hot water pipes to reduce the delays (and wasted water) while waiting for the water to "run hot.
Be sure the water heater thermostat is not set too high. Extremely hot settings waste water and energy because the water often has to be cooled with cold water before it can be used.
