Overview

This is an assembled downstream chemical injector kit built for 5-8 GPM cold and hot water pressure washers. It uses a 20% fixed 2.1mm GP injector to pull liquid chlorine or other cleaning chemicals downstream of the pump, so chemical never runs through the pump. The 1/2" high-capacity flow path and plated quick couplers keep pressure loss minimal, letting you reach higher elevations and farther distances than a typical downstream injector. A plated ball-valve lets you switch between chemical draw and straight rinsing without restricting flow. It's an economical setup for heavy-use cleaning or entry-level soft-wash on your existing machine.

Frequently asked questions

It's designed for higher-flow machines in the 5-8 GPM range, and works on both cold and hot water pressure washers. The 1/2" high-capacity flow path and 1/2" quick couplers are built to match 1/2" ID hose.

No, the chemical does not run through the pump. This is a downstream injector, so it draws and mixes chemical after the pump, protecting the pump from liquid chlorine and other cleaning chemicals.

It comes fully assembled and ready to use. The kit includes the 5-8 GPM 20% 2.1mm GP fixed injector, a plated ball-valve, 1/2" plated quick couplers, an inlet strainer with a 48" chemical inlet hose, and a 24" high-pressure bypass hose.

Yes. The plated ball-valve lets you alternate between chemical application and straight cleaning with no flow restriction or pressure loss, so you get full flow when you switch to rinsing.
