*when trying to figure out whether or not your chemical injector is bad there are a couple of things to look for. If you are using your black soap tip or no tip at all and the injector will not suction your chemical then the first thing to check is to make sure that your spring is not broken or the ball is not corroded. If they both look good then it is time to look for a restriction in your hose or at the gun. The chemical injector works by Venturi, which means it will only draw material when the pressure is low. If you have a kink in your hose or the gun is not opening completely it may add just enough pressure to cause the injector not to suction the chemical.
