It draws one soap or chemical into the water line after your pump, and a lever switches it to a bypass mode for full-pressure rinsing.\u003c\/p\u003e\n\u003ch3\u003eWhat's the difference between the ST-167 and the ST-160?\u003c\/h3\u003e\n\u003cp\u003eBoth are single-chemical downstream injectors. The \u003ca href=\"\/products\/suttner-st-160-single-soap-downstream-injector\"\u003eST-160\u003c\/a\u003e draws soap when your lance is in low-pressure mode, and water always passes through the injector. The ST-167 adds a bypass lever, so you choose soap or rinse at the injector and get full rinse pressure.\u003c\/p\u003e\n\u003ch3\u003eIs this the same injector used in the Premium Single Soap Wash System?\u003c\/h3\u003e\n\u003cp\u003eYes.

The injector nozzle has to match your machine's flow and pressure to draw soap correctly. Call us at 616-777-7175 with your PSI and GPM and we'll confirm the right size.\u003c\/p\u003e\n\u003ch3\u003eWhy isn't my injector drawing soap?\u003c\/h3\u003e\n\u003cp\u003eCheck that the lever is in soap mode, the pickup tube and strainer are clear, there's no air leak at the barb, the soap isn't too thick, and the pickup tube isn't too long.
