How The Blue Streak Dispenser Works

The Blue Streak Dispenser is a chemical injector that adds a metered amount of chemical to the flush line of RV stools. 

The t-valve is a venturi that creates a vacuum to draw the chemical from the reservoir and mixes it with the water passing through the t-valve.  The t-valve also contains a check valve to stabilize the systems between flushes. On the side of the t-valve is a small arrow, which indicates the direction the water needs to flow through it to create a vacuum.
If installed backwards it will not draw chemical from the reservoir.

The metering tip controls how much chemical to water ratio (or mix) you get in the stool. The approximate mix is one ounce chemical to five gallons of water. It should give you a color mix that is between a royal blue and a sky blue in the stool.
The tip is preset and there is no adjustment.

The reservoir, which is mounted on the wall, should be no higher than the top of the stool. It can be mounted lower than the stool or in a basement compartment.
If the reservoir is mounted higher than the stool, the chemical will flow freely into the bowl and give you a very dark blue color.

If you remove the line from the reservoir always be sure to use silicone sealer on the fitting when reattaching the line.  The mold line on the stem sometimes will allow chemical to leak out if you don't.

The tube pinch on the line between the tank and the t-valve is a service clamp, only for use when repairing the stool, or to stop the flow of the chemical.
