Cory Does Not Recommend This Product
This unit includes a siphon tube, which is attached to the barb on the top of the pump right by the high pressure outlet. The filter end of the siphon tube goes into your container of pressure washer-safe detergent, which will be a very thin consistency- more like water than dish detergent. Thick detergent won't work.
Then you must put the black soap spray tip on the end of your spray wand. This opens the valve and allows the water rushing by to pick up the soap and add it to the water stream.
To get the siphon started you may find it helpful to raise the level of your soap container as demonstrated by this Siphon explanation. Once the siphon is going you should be able to put the container on the ground.
If these tips don't help, then you may want to give the folks at Simpson (who make AAA pumps) a call at 877-362-4271 for Factory Warranty advice. The warranty covers defects in materials & workmanship, but it won't cover installation issues.
We appreciate your business, and apologize for any inconvenience.
