Ok, I have been lurking in the shadows reading countless threads On TGS and I love it. Been doing residential and some commercial for about 2 years. The last 8 months I have grown significantly and keep putting the money back into the business. I am a full time Fire Fighter so this is my Full time side job. MY CURRENT QUESTION. I am about to upgrade to an enclosed 6x12 double axle trailer and looking to add hose reels, hose etc.... I have been using my x jet for the last year and man o man how awesome it helps.. However; I would love to have a pump on the trailer pushing my preferred chemicals down 200 +/- ft Kuri tec hose. I am tired of luggin around the 7 gal pail of chemicals with 25 ft hose. I would like to know if i should just look into the fatboy system that pushes 5gpm and use it for house cleaning and roof cleaning when I get into that? Not many pressure washing companies or suppliers around here except oil field type stuff, so I am limited on advice I can find locally. Please, any advice would be nice.... Btw, somehow I have been making ends meet with a VERY SMALL 4x6 enclosed trailer packed to the gills with "2 machines, chemicals, surface cleaner, ladder attached to side, hose attatched to other side, pressure hose attached to the door... MANY MANY more things shoved "organized" withing the trailer. Really looking forward to hose reels and plenty of hose... I appreciate constructive criticism, so please ANY advice.

I just rinse more, to flush a little dirt out. Then when it stops dripping i go back and pass a quick spray "not enough" to get into the nail hole and usually it is gone. Never had too much problem, even on white vinyl. And in Louisiana we have LOTs of mud dobblers and bugs of that sort.. if thats what they call them.

Thanks everyone. I will be calling bob at PT. I need to down stream at least 10:1 which I did not think was possible. I cannot find any 12.5 sh locally so I need a higher ratio injector.

P.S I dont want to Down Stream. I dont want the chemicals in my hose and dont want to have to push over 200' of chemicals to get rinse water.... My goal is One pressure hose with most likely xjet tip for rinsing, and One Yellow chemical hose..... That would be Ideal.... I would be in love...
