Wu, Sam . 2010. Performance of Hoseline Tees with Valves as a Function of Tee-Waterway Diameters. 1051 1302P. San Dimas, CA: U.S. Department of Agriculture, Forest Service, San Dimas Technology and Development Center. 4 p.
The hoseline tee is a fitting that has male and female threaded ends and a male tee branch. It is used for diverting water from a main trunkline to a lateral branch. Previous editions of Forest Service (FS) Specification 5100-107 (before 2005) did not include a minimum waterway diameter for the tee branch. As a result, the branch orifice diameter was very different from manufacturer to manufacturer. In 2005, the Forest Service addressed the problem in its most recent update to FS Specification 5100-107d. In the update, a minimum flow rate through the tee branch is specified for hoseline tees with valves, as well as a minimum waterway diameter for both hoseline tees with-and without valves.
