what do you guys think is best x- jetting or down streaming?
 
Depends on chemical and surface cleaned. Down-streaming is most efficient. If cleaning vinyl, low-pressure should be used and down-streaming or direct application through a low-pressure pump are best.
 
x jet m5 is low pressure. we use it on anything other than concrete
 
what is Down streaming exactly? and what is an x-jet exactly?

Down streaming is the method of inroducing your chems into the water stream after the pump. Both a down stream injector AND and x-jet are considered Down-Streaming. The x-jet is after the gun and has a higher chemical draw rate due to no back pressure and is a high pressure tip.

M5 X-Jet here

Down-streaming only works with low pressure tips to allow injector to draw chem into stream.
 
Xjet is good for applying degreasers and acids. I prefer ds for house washing.

Like everyone else we use both.
 
Am I missing something about downstreaming? I'm genuinely asking - has something changed in the last 2 years since I had a ds setup?

You still have water 'turned on', wet plants decks etc... Walk back to truck and connect chemical then soap everything... Walk back to truck and switch to water again to rinse.... Otherwise you'd have to be doing steps 1 & 3 (pre-wet and rinse) at high pressure, not low pressure, right??

Just use a low pressure rinse tip, or crack your ball valve, or use adjustable wand, with your 25 or 40 tip and just don't turn wand so much that the chem comes out, to rinse. No need to go back and forth to truck. I DS through 200 feet of hose at 8gpm. It takes exactly 10 seconds for the water to go from applying chem to clear water or vice versa. I just change my tip about 10 seconds before I don't need chem or do need it. Average 2500-3000 sq ft take less than 5 gallon of HW mix.
