Venturi feeder bypass and control

An apparatus for use with a fluid piping system for dispensing a measured amount of a soluble chemical into a liquid flowing through the fluid piping system, wherein the fluid piping system includes a canister and a chemical holding container, the canister having a cavity in which the chemical holding container is placed and an opening allowing access to the cavity, comprising:

• a. a cap member, said cap member being configured and arranged to cover the opening of the canister and having a first end and a second end;
• b. a fluid flow conduit, said fluid flow conduit extending through said cap member from said first end to said second end and having a reduced diameter proximate a center portion thereof;
• c. an inlet port of said fluid flow conduit, said inlet port being proximate said first end;
• d. an outlet port of said fluid flow conduit, said outlet port being proximate said second end;
• e. a first passageway positioned upstream of said reduced diameter of said fluid flow conduit and providing fluid communication between said fluid flow conduit and the cavity;
• f. a second passageway providing fluid communication between the cavity and said reduced diameter of said fluid flow conduit;
• g. a first opening located in said cap member proximate said inlet port of said fluid flow conduit;
• h. a second opening located in said cap member proximate said reduced diameter of said fluid flow conduit;
• i. a first control member, said first control member being configured and arranged for insertion into said first opening, said first control member controlling fluid flowing from said fluid flow conduit into said first passageway;
• and
• j. a second control member, said second control member being configured and arranged for insertion into said second opening, said second control member controlling fluid flowing out of said second passageway into said fluid flow conduit, said first control member including a first stem and a first bushing and said second control member including a second stem and a second bushing, said first and second stems each having a threaded portion and said first and second bushings each having a threaded inside surface, wherein said threaded portion of said first and second stems is operatively connected to said threaded inside surface of said first and second bushings, respectively, and said first bushing is operatively connected to said first opening and said second bushing is operatively connected to said second opening.

• f. a second passageway providing fluid communication between the cavity and said reduced diameter of said fluid flow conduit;
• g. a first opening located in said cap member proximate said inlet port of said fluid flow conduit;
• h. a second opening located in said cap member proximate said reduced diameter or said fluid flow conduit;
• and
• i. a first control member and a second control member, said first control member being configured and arranged for insertion into said first opening for controlling fluid flowing from said fluid flow conduit into said first passageway, said second control member being configured and arranged for insertion into said second opening for controlling fluid flowing out of said second passageway into said fluid flow conduit, said first control member and said second control member have an open position and a control position, whereby fluid is prevented from flowing into said first passageway when said first control member is in a closed position and fluid is prevented from flowing out of said second passageway when said second control member is in a closed position.
