I'm new to PWR and the business

Hi everyone. I am new to the pressure washing business and have found some good information on this forum already. I have only cleaned a handful of residential homes and 1 commercial concrete job. I do have some promising bids out there, but things are tight just starting up.
I did read about some DS injectors someone was talking about. I need a new one and read of Bill’s injector. What’s the real name and where do you get them?

Central South Carolina

PowerWash.com or Bob from PressureTek, they’ll have the injectors you need. Make sure the flow is going the right way, or it won’t work. Also make sure the injector is for your GPM machine.
