Faucets, Toilets and Shower Heads

High efficiency toilets have redesigned bowls and tanks that use 1.28 gallons per flush as compared to 1.6 gallons for the previous generation of efficient toilets. A dual-flush toilet differs from traditional siphon-flush toilets in that it relies on gravity to remove waste from the toilet. The name dual-flush comes from the fact that it has two buttons for releasing water. It outputs water in both 0.8-gallon and 1.6-gallon capacities. The smaller level is designed for liquid waste, and the larger is designed for solid waste. The dual-flush toilet can save up to 67% of water usage.

Low-flow faucets and showerheads have a flow volume of less than 1.75 gallons per minute. If high efficiency toilets, low flow faucets and showerheads are installed, a smaller water heater and smaller-diameter piping can be used.
