What happens here

Before applying soap, hook up a standard garden hose to the unit for water supply. To apply detergent, use the downstream chemical injector, which operates via a Venturi system. When the secondary trigger on the wand is squeezed, it creates low pressure, sucking detergent from the chemical bucket up through the injector and out the hose. There is no need to go back to the unit to flip a switch or turn a dial for soap application.

Goal: Apply detergent effectively using the downstream injection system.

Tools and materials

  • Chemical Bucket — Holding the detergent
  • Downstream Chemical Injector — Drawing detergent into the water stream
  • Garden Hose — Supplying water to the pressure washer
  • Pressure Washer Hotsy — Applying detergent and rinsing
  • Detergent — Cleaning the equipment

okay of the machine got it yep okay now we've hooked our water up so we're just using a standard garden hose nothing special uh and then what about soap what do we do with soap so soap we're going to be using what's called Downstream so it's a chemical injector that uses a Venturi inside so this part right here this brass piece is your injector okay so when I squeeze this secondary trigger here and this one it's going to create a low pressure that's going to then suck detergent up through that injector and then out my hose you said low pressure and there's something I know about Hotsy and that they their pumps run at about half of the PSI as other people's pumps or something like that I don't know what it is what is it half the RPMs is the standard motor yes so it's half the RPMs easier on the machine we're going to spend lower RPMs so we've got a primary trigger for the soap yep and then we got our high pressure nozzle okay this is our soap nozzle so the reason why it's a bigger orifice is that it will let more air more water out to create a soap injector but then it as soon as you hit the soap trigger it goes low pressure yep automatically you don't do nothing else you don't do anything so you can be 200 feet away from your unit and pull detergent but I would even have to go back to the unit to flip a switch or turn a dial all right Stone aim at anyone and don't none of this no triggering it like this when you're using don't play with them you're gonna have it on and that's and that's it play with your leaf blower not with your pressure washer yeah there you go all right well let's fire it up then all
