Proportioner for newbie

[TexasPressureWashing]

DIY proportioner (Exact Parts List as the ones selling for $400)

These are the exact parts used on the “dougenator” or the “infuser” sold by another vendor. No idea on patents, just giving out the info. Build you own for $120 [image] [image]

Proportioners

I’m about to build my roof system. More than likely im going with air. Is a proportioner really worth the extra money $1295? I’m mostly going to do residential roofs and use it for post treating driveways. That’s the plan for now

Also @Racer uses this one I believe right?
