Even small drips can waste thousands of gallons of water, as much as 150 gallons a day. Be sure to check under sinks for moisture or small leaks. And always repair leaky faucets right away to avoid paying for wasted water, and also to avoid water damage to your fixtures and pipes and surrounding areas. Remove and clean your faucet aerators annually to ensure an even flow of water. Make sure overflow holes on tubs and vanities are clear and open to prevent water damage to floors and ceilings.
