Buy a high efficiency toilet
Toilets are responsible for 20-40 percent of our indoor water usage. That’s why replacing old, inefficient toilets tops the list of ways to conserve water in your home. A new high-efficiency toilet (HET) will save 20-60 percent per flush, for a significant reduction of 13,000 gallons annually. Crazy. To really go the distance, consider a dual-flush which can save even more water.
