DS Guru High-Draw Downstream Chemical Injector Kit

The DS Guru High-Draw Downstream Chemical Injector Kit is designed for professional pressure washing contractors looking to achieve increased chemical draw while maintaining the convenience and simplicity of a traditional downstream injection system. Available in 1553 and 1917 injector models, this kit offers an alternative for contractors looking to improve chemical application performance without the need to utilize a separate, dedicated softwash system.

Developed by a fellow pressure washing enthusiast, this injector was born from a desire to push the capabilities of traditional downstream injection. Through a determination to achieve stronger chemical draw ratios without the added equipment, expense, and complexity of a dedicated softwash setup, the goal was simple: get a little more cleaning strength out of the pressure washer you already own. This injector is intended to help bridge the gap between conventional downstream chemical application and dedicated softwash equipment, offering the potential for increased chemical concentration while retaining the convenience of downstreaming.

Each kit comes equipped with an upgraded stainless steel chemical check valve, your choice of a 1/4" or 3/8" stainless steel hose barb, and 3/8" stainless steel quick-connect fittings for convenient installation and removal.

Key Features:

• High-Draw Downstream Injector: Designed for introducing cleaning chemicals into the water stream after the pressure washer pump.

• Two Injector Models: Choose between the 1553 and 1917 configurations to match your pressure washing setup.

• Stainless Steel Check Valve: Helps prevent reverse flow through the chemical injection line and supports reliable chemical pickup.

• Stainless Steel Hose Barb: Available with your choice of 1/4" or 3/8" hose connection to accommodate different chemical feed line sizes.

• Stainless Steel Quick Connects: Includes a 3/8" stainless steel male plug and female coupler for connecting the injector to your pressure washing system.

• Convenient Installation: Quick-connect design allows the injector to be connected, removed, or replaced without disconnecting threaded plumbing.

• Contractor-Oriented Configuration: Includes the essential injector, check valve, and connection fittings together in one kit.

Important Notes:

• Select the appropriate injector model based on your pressure washer's flow characteristics and downstream chemical application requirements.

• Chemical draw rates vary depending on pump GPM, operating pressure, injector selection, hose length, chemical supply plumbing, and nozzle configuration.

• The injector must be used with a suitable low-pressure nozzle to activate chemical injection.

• The 1/4" and 3/8" hose barb options refer to the chemical suction line connection, not the pressure washer's high-pressure hose connections.

• Flush the injector and chemical check valve with fresh water after each use to help minimize chemical buildup and extend component service life.
