DS Injector pressures

Has anyone ever done a test to see exactly what PSI the general hi-draw and other injectors will operate at. I am wondering if sometimes were running too much pressure and sacrificing less chemical being injected into the line. I cant see a difference in using a 30 or 50 oriface on an 8gpm machine but just wondered if there is.
 
Chris, are you having trouble drawing enough chems? Sometimes I wish I could slow mine down. Be sure you have a good trigger gun with at least a 10 or 12 gpm flow. I had a good gun go bad and needs rebuilt...it just won't pull chems anymore but rest of my guns do fine. I always cut about 1/4 or 1/3rd off the check spring and stopped most trouble I was having with injectors. I am primarily using a Super Suds Sucker and really like it.
 
Not having troubles drawing just wondering if anyone has found a sweet spot with injectors. We run open guns so no problems there. Our only trouble is rebuilding injectors quite frequently. Its gotten to the point where we just toss them into the van and after we get to the last one thats good well rebuild them all. The o-ring is the only thing that goes bad on these injectors I wish I could just buy a 100 pack of them and we would save a few dollars per injector per rebuild. It adds up when your burning through them frequently.
 
We obliterated downstreamers at the rate of one ever two weeks for a while cleaning hoods and downstreaming caustic. I thought it was something we were doing and kept killing regular general downstreamers. We switched to the adams down streamers and not only did they draw more consistently they lasted 2 to 3 months before requiring internal care. I found the adams well built but still needed maintinance.
Out soulution was the check valve down streamers from Bob at Pressure Tek. We have run 4 of them consitently for over 10 months before they required any maintinance and after 10 months we simply found the base had worn so much that the ball would not seat and would allow blow by back into the chem mix. I can not speak highly enough about his downstreamers.
 
go to harbor frieght and buy a box of O rings. It was the best investent I ever did. Now I can just replace the bad O ring in a few minutes for pennys.

Downstreaming is old news! Foam is where its at!

I wish I could shoot foam 40' high like I can downstreaming.
