If I’m using 10% sh and I want to hit 1 chemical to 10 water where would I keep the adjustable piece at?
1 answer-
ProductExpert6· 3 years ago
When the injector is fully opened it would be giving you 15%. You will need to adjust it down from there to the desired % of flow you want. There is no set number to recommend for the 10%.

Per the manufacturer, there is not a pressure range for this chemical injector. As long as a chemical or soap nozzle is used, it can be used with a pressure washer that produces a max 3500 PSI.

The chemical injector is adjustable from 0 to 15%. If it is all the way open, it would have an 85% water to 15% chemical ratio.

Where does this get inserted? Between the wand and the pump? I have a 1700 PSI 1.5 gpm washer. Will this still work to draw in soap in the high pressure point?
1 answer-
ProductExpert6· 5 years ago
This soap injector would be installed after the pump. It can only be used on low pressure.
