President Trump has expressed frustration with low-flow toilets and shower heads, claiming they require multiple flushes and only produce low water flow. He has directed the EPA to review water efficiency standards for these products. However, environmental advocates argue that water conservation standards help ensure adequate long-term water supplies and that the EPA's WaterSense program has already helped save over 3.4 trillion gallons of water. Rolling back these standards could undermine years of water conservation efforts.
