How to Change the Metering Tip:
• Remove the chemical feed hose from the barb on the side of the proportioning valve.
• Unscrew and remove the old tip.
• Screw in the proper tip for your chemical tip and place the hose back on the barb
Proportioning Valve
Metering Tip Kit (Hydro-Force Item# PDE001) contains 14 different colored metering tips, allowing
dilution rates from 11:1 up to 427:1. Refer to the chart below to select the tip that meets the dilution rate for
your chemical application.
• For example: if you require 1-1/2 ounces of chemical per gallon of water, change to the red metering tip
with the dilution rate of 85:1.
• The dilution rates are based on chemicals with water-like viscosity. Thicker (more viscous) chemicals will
dilute at a different rate.
• For powdered chemicals, a liquid concentrate must be made. Mix the concentrate according to the
manufacturer's directions, and then select the appropriate metering tip.
• Contact your distributor or Hydro-Force if you have questions about your chemical.
