Overview

This is a fully assembled downstream bypass chemical injector for 6-10 GPM cold and hot water pressure washers, built around a 20% fixed GP injector body with a 2.3mm orifice. The bypass design delivers higher concentrations of liquid chlorine or other cleaning chemicals at longer distances and higher elevations, with none of the pressure loss you get from a typical downstream injector — and chemical never runs through the pump. The kit includes a plated ball valve, plated 1/2" quick couplers (for 1/2" ID hose), an inlet strainer with 48" chemical suction hose, and a 24" high-pressure bypass hose. It's an economical setup for heavy-use or entry-level soft-wash work on your existing machine, letting you alternate between chemical application and rinse with no flow restriction.

Frequently asked questions

It's built for higher-flow machines running 6-10 GPM, cold or hot water. The plated 1/2" quick couplers are designed for use with 1/2" ID hose, so it drops inline on rigs already plumbed with 1/2" quick-connects.

No — chemical never touches the pump. This is a downstream injector, so it draws chemical after the pump on the outlet side, which is why it's safe for liquid chlorine and other harsh soft-wash chemicals that would damage pump internals.

The bypass lets you alternate between chemical application and high-pressure rinse with no flow restriction or pressure loss. A typical downstream injector stays inline and costs you pressure; this setup delivers full flow and reaches longer distances and higher elevations while drawing a stronger 20% concentration.

The kit arrives completely assembled and ready to use. It includes the 6-10 GPM 20% GP 2.3mm injector body, a plated ball valve, plated 1/2" quick couplers, an inlet strainer with 48" chemical suction hose, and a 24" high-pressure bypass hose.
