A flow restrictor limits the amount of liquid or gas, such as water or air flowing out of a tap or shower. Tap aerators mix air and water to control the amount of water that flows through the tap without affecting the water pressure. These devices introduce air in to the water stream and as air occupies spaces, that were earlier occupied by water, this reduces the amount of water flowing out. These serve to lower water bills and are environmentally friendly. With these, one can save on water usage and save on water bills. At AQVA Bathrooms, we offer a series of aerator kits. With aerator kit installed in taps, the amount of water utilized is low, compared to the tap without an aerator kit.
