The effect of three or more such vertical walls or ribs has not been determined. In such cases, the air gap shall be measured from the top of the wall. , The effective opening shall be the minimum cross-sectional area at the seat of the control valve or the supply pipe or tubing which feeds the device or outlet. If two or more lines supply one outlet, the effective opening shall be the sum of the cross-sectional areas of the individual supply lines or the area of the single outlet, whichever is smaller. . Air gaps less than one (1) inch (25 MM) shall be approved as a permanent part of a listed assembly that has been tested under actual backflow conditions with vacuums of from 0 to 25 inches of mercury, NOTES: 1, Air gap protection may be used in lieu of mechanical backflow protection, with EWEB or SUB approval in their respective service area. 2. All air gaps are measured from the bottom of the supply line to the top of the overflow rim of the sink or basin that is being filled. The air gap shall be twice the diameter (2xD) of the supply line, but in no case less than 1", If the supply line is adjacent to a wall, the air gap shall be increased to three times the diameter (3xD) of supply piping. 3. If the supply line is cut at an angle, the point closest to the basin is used for measurement. 4. If the supply line is reduced at the opening, the diameter used for air gap is taken at the largest portion of the supply piping. 5, There shall be no extensions or attachments on the open end of the supply piping. Any such extensions or attachments will void the air gap protection, 6. Reference document-Uniform Plumbing Code, Chapter 10, Section 1003, minimum air gaps for water distribution.
