Downstreaming - how do you start and stop your mix?

I ran a 4K @ 4200 all year last year. Left it idle without bypass for 20 minutes at a time…nothing bad happened. Cat pump, Honda engine

Same machine. Honda 390 with Cat pump. 4200/4

Yep, about to call PWP right now.

Me too
Lori told me last night they just got 1/2 check valves

Wouldn’t a 3/4" proportioner be more effective?

Damn right it would. Building that system after this project is done.

Would like to know how that turns out.

Ball valve man or release the trigger!

That’s how we house wash.
