When this is done, the SOFA <br />flow rating is based on the smaller of the two pipe sizes. (§ 3.5.1.1).<br /> <br />•Reduced Pipe Size: When there is a reduction in pipe size within 16” as defined by the F limits, the flow rating for the SOFA shall be <br />based on a smaller pipe size that is listed in the specifications table. <br /> <br />•Increased Pipe Size: When the pipe size is increased within the F limits, the rating for the SOFA does not increase, the SOFA rating <br />shall be based on a smaller pipe size listed in the specifications table. <br />10” Round Universal Cover for Retrofit and <br />New construction
