I just got back from the Coleman web site. You are absolutely right Jody. I have the low pressure soap or solution injection tip that I had a case of the dumb ass and did not install on the pressure wand. :duh: The owners manual I have does not say anything about the solution injection. I will try it again tommorow. Thanks for the tip Jody!Originally posted by jodyand
Chief it has to be on low suction for it to work. If it a cheap-o like mine then you have to pull the adjustable tip out. If its more expensive model then you have to put the low pressure tip in.
X2, I have done this with just water to get the dust off the bricks, did not use soap. I had no problems, and it is much more efficient then a garden hose alone.As long as yo use the fan pattern and not the jet pattern i don't think you would have a problem. That is as long as your mortar don't crumble when you touch it. Test it on a spot thats not to noticeable and see what happens.
