5000 PSI Downstream Injector

The General Pump 100861 is a downstream injector for pressure washers and car washes. Plus, it is used in applications that require a high draw rate. It features an adjustable 1/4-inch hose barb, allowing you to control the chemical injection ratio into pressurized fluid streams. This pressure washer downstream injector is built with stainless steel for superior corrosion resistance and it is engineered to endure a maximum operating pressure of 5000 PSI. General Pump produces this stainless steel downstream injector here in the United States so you can take pride in purchasing an American-made product for your car wash or pressure wash business.

Features:

• Adjustable
• Up to 20% injection draw rate
• Made in America

Installation:

• Install valve with direction arrow pointing downstream. For proper operation, a control device such as a dual lance wand, quick couple nozzles, or an adjustable nozzle holder must be used to lower the system pressure at the nozzle. Warning: Under no circumstances should the system pressure exceed the maximum rated pressure of any component.

Troubleshooting:

• Injector will not draw liquid
  • Cause:
    1. Incorrect nozzle
    2. System is not in low-pressure mode
    3. Discharge hose is too long 
    4. Chemical line is clogged
  • Solution:
    1. Check and change the nozzle
    2. Change or adjust the nozzle to put the system in low-pressure mode
    3. Reduce the length of the discharge hose or change the injector
    4. Clear chemical line of obstruction
• Rate of draw seems too slow
  • Cause:
    1. Discharge hose is too long
    2. Air leak in chemical line
    3. Chemical is too viscous
  • Solution:
    1. Reduce the length of the discharge hose or change the injector
    2. Locate and repair the leak
    3. Reduce the chemical with water to decrease viscosity
• Chemical injector is leaking from hose barb
  • Cause:
    1. Obstruction in hose barb check valve
    2. Damaged O-ring in check valve
  • Solution:
    1. Disassemble and remove obstruction
    2. Remove and replace O-ring
• Excessive pressure load on pump, motor, or engine
  • Cause:
    1. Clogged injector
    2. Improperly sized injector orifice
  • Solution:
    1. Clear injector orifice of obstruction
    2. Change orifice
