One embodiment includes a rotatable member that is rotatable from a fluid stream obstructing condition to an out-of-the-way condition to prevent fluid diversion into the dispersal valve. Another embodiment includes a lever handle for quickly setting the amount of fluid being diverted into the inline dispersal valve. Another embodiment includes an indicator that can be viewed from a position above the inline dispersal valve. Another embodiment includes a cap that can be secured or removed without the aid of tools. Another embodiment includes a clip that allows one to disassemble the inline dispersal valve for servicing. Another embodiment includes a dispensing valve that can be reversed and still properly divert fluid into a dispersant chamber. Another embodiment includes an inline dispersal valve with a bleed valve positioned to allow one to bring the air volume in the dispersant chamber to the proper level. ## Claims ### Claim 1 A method of replenishing an inline dispersal valve comprising the steps of: grasping a set of integrally formed, ergonomically shaped, radially protruding handles of a cover housing; rotating the cover housing of a dispersal valve cover in a first direction without rotating a cap of the dispersal valve cover to unlock the dispersal valve cover from the a dispersal valve housing; further rotating the cover housing in the first direction to remove the dispersal valve cover from an open end of the dispersal valve housing; removing the cap from the dispersal valve housing to access a chamber of the dispersal valve housing; placing a dispersant within the chamber of the dispersal valve housing; placing the dispersal valve cover on the open end of the dispersal valve housing; and rotating the cover housing in a second direction to move a portion of the cap into a locking fluid tight engagement with the open end of the dispersal valve housing to provide for fluid tight enclosure of the chamber of the dispersal valve housing. ### Claim 2 (depends on 1) The method of claim 1 wherein the step of placing the dispersal valve cover on the open end of the dispersal valve housing comprises placing the dispersal valve cover on the open end of the dispersal valve housing with a female threads of the cover housing engaging a male threads of the dispersal valve housing and the step of grasping a set of integrally formed, ergonomically shaped, radially protruding handles of a cover housing comprises grasping a set of four handles that are located opposite each other to provide a balanced rotational force of the cover housing. ### Claim 3 (depends on 1) The method of claim 1 wherein the step of placing a dispersant within a chamber of the dispersal valve housing comprises the step of filling the chamber of the inline dispersal valve housing the dispersant and the step of grasping a set of integrally formed, ergonomically shaped, radially protruding handles of a cover housing comprises grasping two handles. ### Claim 4 (depends on 1) The method of claim 1 wherein the step of placing a dispersant within a chamber of the dispersal valve housing comprises the step of replacing a depleted dispersant supporting canister with a fully charged dispersant supporting canister. ### Claim 5 (depends on 1) The method of claim 1 including the step of rotating the cover housing in the second direction to move the portion of the cap against a sealing ring to compress the sealing ring to provide for a fluid tight seal.
