Could one of you veterans. Explain to me what is downstreaming and Upstreaming of chemicals such a bleach. R-109 rd1430 etc.

Does this mean it not going from pump to spray Gun. Is it just the opposite.

Up goes thru your pump

Down just goes thru. your hose and gun

up still goes thru your gun but down dont go thru pump!!

I would not put bleach thru the upside!!
