Lots of ways for this to go wrong.
Pressurized hose blowing off in your face when disconnecting from machine.
Arisolized chemical residue to breath in while disconnecting.
Adding foam to sprayer tank.
Charging the product pump with air and vaperlocking the whole system.
I'll pass. Just run your Chemical in about midway through filling, then Finnish with water. I have a valve in the end of my fill hose, and one at sprayer. I only lose a cup or two full of clean water when disconnecting. Yes the hose is charged full of water but a 2" hose charged with water isn't any problem to get folded back on the truck.
