Back when I X-Jetted, just like you, I considered downstreaming chems through the hose (and wearing it out faster) to be an issue. Ever since I’ve been downstreaming and not toting that soap bucket around I don’t see it as an issue at all.
A rubber hose can easily be replaced but I don’t guess one can really replace their back.
The benefits of downstreaming outway any drawbacks by far.
With the right downstreaming nozzles (low rinse, high rinse, low soap high soap) that match up correctly with your machine you’ll get a much more efficient stream than with the X-Jet. There are some other all-in -one types of downstreaming nozzles but I really haven’t used them. I think Micah and Tony Evans use the Hi-Lo nozzle so maybe they can offer a bit of info about it.
One of the big drawbacks with the X-Jet is that the stream turns into mist when shooting high.
Nice video. If you don’t mind answering. What is your chemical and how effective is it on black mold and mold on gutters? Do you have to put a brush to the house anywhere? Or spray, dwell, rinse, leave?
