Solution hose pressure affects how much chemical is drawn from the Hydro-Force injection sprayer. Higher pressures decrease the ratio of chemical to water and lower pressures increase the ratio of chemical to water. If you are using pressures ranging from 50 to 200 PSI, you’ll want to install the low pressure knob (NA0868) so your dilution ratios are more properly calibrated. We recommend using 100 PSI when using the low pressure knob for the most accurate dilution ratios.
