Conserve and Save

That is approximately 10 gallons of saved water a day and 3,700 gallons or more per year! Better for the planet and better for your wallet, dual flush toilets help make conservation easy.

*The average American flushes five times a day at home. Assuming an average household of 3.2 people over 365 days.
