Overview

\n

Meet the JOEJET Downstream Injector Kit, a compact solution designed to work with your pressure washer to dispense cleaning detergent from a separate reservoir. By leveraging the siphon principle, it helps you tackle grime on driveways, cars, roofs, and walls with controlled chemical delivery while keeping your pump safe and performing at its best.

\n

A simple, all-in-one setup makes installation straightforward. With 3/8 inch quick-connect fittings on both ends, the kit sits between the pump and hose to prevent backflow into the pump, supporting your cleaning workflow without added risk to your equipment.

\n

Important note

\n

Note: When installing, align the arrow on the injector with the direction of water flow; misalignment can prevent the unit from functioning correctly.

\n

Materials and capacity

\n

Constructed from brass and stainless steel, the injector resists chemical wear and can handle up to 3200 PSI with a 2-3 GPM flow, making it suitable for a variety of cleaning tasks.

\n

The rugged build is designed for regular outdoor use and different cleaning detergents, balancing durability with performance.

\n

Real-world uses

\n

In everyday tasks, you can treat concrete with detergents for driveways and sidewalks, refresh car exteriors, and prepare roof or wall surfaces before rinsing. The downstream approach keeps detergent separate from the pump, allowing you to control application more precisely.
