SEAL DEPTH 7.I.D. PIPE AMERICAN DIAL-A-FLOW PATENT NO. 4,298,470 Flow Control: The Amercian Dial-A-Flow provides a circular weir. Each outlet of the distribution box will equally discharge wastewater upon rising water level in the box. When the opening becomes submerged, the dial-a-flow becomes an orifice and further enhances equal distribution. The discharge rate of each dial-a-flow is depicted in the graph. The head condition is noted in inches above the invert of the orifice and is based on open discharge. The graph was derived from testing in a laboratory environment. 4" Nominal Schedule 40 Sdr 35 Astm 3034 Astm 2729 S & D Corrugated Installation Instructions: 1.Cut pipe as evenly as possible and remove shavings. 2.Insert pipe into distribution box and extend pipe 1" into box. 3.Insert dial-a-flow into pipe ends with opening to one side. (Do not use glue) Note: Proper cutting of corrugated pipe will result in dial-a-flow snapping behind one corrugation. 4.Level pipe individually or place level on orifice lip. 5.Purge pipes in concrete boxes into place with suitable material. 6.Fill with water and "dial up" each pipe to water surface. SPECIFICATION: DIAL-A-FLOW Provide a non-corrosive flow control device to be rotateably secured in the discharge piping of the drainfield distribution box. The device shall have an eccentrically located circular opening with a diameter of 1-15/16". This will provide a uniform in any rotated position. The device shall have a leveling lip extending into the box 1/8". The sealing means shall be a cylindrical extension inside the pipe with radially extending seal to initiate contact with pipe at least 3/4" inside the pipe. The device shall be provided with a gripping edge on the periphery of the end faces for easy rotation. The gripping edge shall consist of six uniform extensions and valleys for easy finger gripping. The device shall be made of low density polythylene, and one piece construction. This seal shall also be capable of snapping behind a corrugation of standard 4" corrugated pipe. The flow control device shall be Dial-A-Flow as manufactured by: American Manufacturing Co., Inc., Manassas, Va.
