This nozzle is intended for use with a down stream injector and a pressure washer
to spray the mixed chemical with the pressure washer pumped water supply.
If you are not intending to spray a chemical mix using a downstream injector then the hose could be much longer.
Note: As the hose length increases there ia an accumulated back pressure in the line.
The downstream injector works on a pressure differential between the water being pumped by the pressure washer and the draw tube drawing the chemical
As the pressure in the line increases less and less chemistry is pulled from the chemical container and become added to the water.
In summary the chemistry mix becomes weaker and weaker as you add hose length.
Therefore the manufacturer provides guidance to indicate that 100ft is a length they are recommending as the longest length.
In reality, the length and the added pressure caused by added hose has some variability,
for instance going up in a lift, aerial platform, will cause a much larger pressure problem and weaken the mix percentage than merely having the hose run across flat ground.
Going up in a lift 25ft will cause more back pressure than the 100ft of hose on flat ground
