For water delivery systems to taps and basins, particularly with good main supply pressure, this air is usually flushed through with the water flow and does ...

Faucets that meet energy efficiency standards for WaterSense mustn’t use more than 1.5 gpm, a 32% decrease in flow rate over the federal requirement. [10] Reduced flow faucets often make use of flow restrictors or faucet aerators to reduce the ...
