I’ve never seen a proportioner except in pics on this site so I couldn’t tell you
Avert your eyes if wooden skids offend you…
I was limited by what was locally available - couldn’t even get my hands on a 1/2" cross. The only place I’ve found the 1/4 3 ways available in Canada is through Grainger and they want $50 + shipping per. Top line goes to water, middle to soap/whatever I want, bottom to SH. Waiting a bag of 1/4 check valves so I can have water and SH open at the same time.
Haven’t done a draw test, except that it pulls enough SH and soap to wash dirty siding 
.
We’ll see how long these ball valves last since they’re not really getting flushed.
Will us plastics not ship to you?
It seems they will. Just put a request for a shipping quote. Thanks, I had just searched “3 way poly valve” when I was first looking and the first few vendors I saw didn’t ship to Canada at all.
