Hi All, Having read / watched etc. I _think_ I’ve got a sense of where all the various bits of pressure washing equipment go and connect up with each other - as per the below diagram. Dotted lines are to suggest optional equipment. This doesn’t have what, set-up how, used when, etc. - one understanding at a time 😅 If you get a moment could you review and see if I’m missing anything? ![image](https://pressurewashingresource.com/community/uploads/default/original/3X/5/5/552af264a2dcb886dab17522e6936f62f3315f20.jpeg) Thanks, Kewin ---

The downstream injector is on the machine right after the unloader. You’ll then have a short ‘whip line’ going to your reel which has the pressure line on it. The supply/garden hose is on a reel, then a short hose to the buffer tank from it to the top with an automatic valve to prevent overflowing (Hudson). That being said you’ll need a gear or belt drive machine to draw from a buffer tank, not the direct drive pictured. And the hose reels pictured aren’t for professional use. Are you located outside the US? ---

Hi Chris, Thanks for the reply- yep, UK based here. Interesting on the positioning of the injector. Unless I’m not understanding what I’m looking at (very possible ;} ) I’ve seen both positions being used. In this one the injector is plugged onto the trigger, with the main pressure hose running from the trigger to the washer. ![image](https://pressurewashingresource.com/community/uploads/default/original/3X/7/6/76ac1bbc7593c317769b224e23411873ad9479a3.png) Whereas here it’s configured as you suggest. ![image](https://pressurewashingresource.com/community/uploads/default/original/3X/2/c/2c9cf6304716921ae71d598aa5961ab3ecb52590.jpeg) Not sure on the physics, but certainly more practical I would have thought or is this something to do with ground level / roof level working? 🤔 Tweaked the picture to be more representative, but thanks for the equipment pointers. Will be picking the ‘what’ is needed once I have a proper grip of ‘how’ this all works together. ![image](https://pressurewashingresource.com/community/uploads/default/original/3X/e/3/e351e6aeecef1c2d1bcbd1719eb903e8d6f96ea0.jpeg) ---

Aha, thanks for the clarification. Had to be something simple 🫠 ---

Xjet is almost identical to an injector, just attached at the gun and can potentially draw 2-3 times as much chem. Drawback is you have to carry around a pail of SH which can be problematic. I ditched mine after a few months. Many of us nix the xjet and switch to a dedicated 12v chem application system, and when you REALLY get the big-boy jobs you switch to an AR45 or air powered system.
