Troubleshooting Your Downstream Injector: Why It Won't Suck Bleach

This episode addresses common issues that prevent a downstream injector from suctioning bleach effectively, shared during a training session. Reasons include improper orientation of the injector indicated by an arrow, the use of wrong size tips, and the effects of too much pressure leading to friction loss, which in turn affects the injector's performance. Other potential problems discussed include kinked hoses and faulty pressure washing guns. 

It also explains how downstream injectors work, utilizing atmospheric pressure and flow dynamics, and counters the myth that they can't be used for soft washing. 

Practical tips and a step-by-step guide on identifying and rectifying these issues are provided to ensure effective operation of downstream injectors.
