Abstract: A flow increasing insert member for a faucet valve body includes a notch therein. The insert member is sized to fit within a cavity passage in the valve body. The notch and the bottom surface of the cavity passage form a passage therethrough of lesser cross sectional area compared to the cavity passage and has a contoured surface to provide for a laminated and less turbulent flow as compared to the cavity passage. The insert member maintains the advantages of quiet opening of the valve body by not interfering with the function of the specifically shaped inlet through the bottom surface of the valve body. In addition, the insert member allows for restricted flow through a groove about the circumference of the valve body when in a partially open position.
