Overview

This is a fully assembled 5-8 GPM downstream chemical injector with a plated bypass ball-valve and 3/8" quick couplers, built for cold or hot water pressure washers. It draws chlorine or other cleaning chemical downstream (after the pump, so nothing corrosive runs through it) at a 20% fixed rate using a 2.1mm metering orifice, then lets you flip the ball-valve to bypass and rinse at full pressure with no flow restriction. The larger 3/8" flow path holds more flow and pressure than a typical injector, so you reach higher and farther with less pressure loss. An economical entry into soft-wash for anyone running an existing high-flow machine.

Frequently asked questions

It's built for cold or hot water machines running 5 to 8 GPM, with 3/8" plated quick couplers that connect to 3/8" ID hose. Match your machine's flow to the 5-8 GPM range and confirm your hose is 3/8" ID before ordering.

No. This is a downstream injector, so chemical is drawn in after the pump. That keeps corrosive chemicals like liquid chlorine out of your pump and lets you apply at full flow without pressure loss.

It comes fully assembled with the 20% 2.1mm fixed chemical injector, plated ball-valve, 3/8" plated quick couplers, an inlet strainer, a 48" chemical inlet suction hose, and a 24" high-pressure bypass hose. It's ready to use out of the box.

Flip the plated ball-valve. One position draws chemical downstream at the 20% rate; the bypass position sends full flow and pressure through for rinsing with no restriction or flow reduction.
