Same draw as the brass GP Hi-Draw in a stainless body that shrugs off chemical, which matters if you run acids or just hate replacing injectors. Which size? 2.1 mm for 3 to 5 GPM machines, 2.3 mm for 5 to 8 GPM, and go one size down once you're running 150 to 200 feet of hose (the 2.1 is what most 4, 5.5 and 8 GPM rigs end up on). Our downstream calculator picks the size from your GPM and hose length and gives you the bleach-to-water mix for it. For setup, sizing and troubleshooting, read the complete downstreaming guide.

Our storefront stocks thousands of parts, chemicals and supplies, most in-stock orders ship the same day, and when you call 503-403-6185 you talk to people who have run this gear.
