    Can someone explain to me what down streaming is and exactly how to do it? We do lawn care in a gated community here and I 've noticed most of the houses are in dire need of cleaning. They are all 100% hardi-plank siding. I have seen some videos of down streaming but am not sure how to set up for it or what chemicals to use. Any help would be appreciated. thanks

    From what I have researched on this subject: Downstreaming is applying the chemical AFTER the pump. It seems most people use a mix of 12% sodium hypochlorite and Simple Cherry house wash. You apply the mix with low pressure, let it sit for a couple minutes, then rinse with low pressure and high volume.
    I am by NO means an expert on this subject, but I have read up on it a little.

    Thanks. I try to research things as much as possible before I actually get into it.

    so basically there is no way to achieve this for those of us who already own High pressure systems without investing a mint into another type wahsing system?

    What would I need? I can handle 75 easily. I think the wife would kill me if I spent a few thousand on a big system right now. She made me swear at leasst one season without a major purchase! LOL

    Grits nailed it,the chem injector hooks to the pressure hose off of the outlet of the pump so your chems do not run thru the pump,you take a ball valve or chem wand with soap nozzle,and spray the chems on what you are cleaning.
