Lowest pressure hose end applicator

I'm part way through a big new construction brick acid wash job, and I'm wishing I had a lower pressure detergent applicator than the mjet. I know downstreaming with a soap tip is lower pressure, and we do it all the time, but I can't get the concentration I need for this job that way. Are there other hose end soap applicators like the xjet and mjet on the market that have a larger orifice for slightly lower pressures? Any other ideas?

Dedicated pump?

Ah yes...but I love the convenience of not mixing chems and messing around with another pump and hose etc etc. In the last 10 minutes I just disassembled my mjet, pulled out the orifice and drilled it out larger with a 3/32" bit. According to the nozzle chart .094 is about a #14 nozzle. Should be lower pressure, now I got to test if it still draws chems.

Pat Norman modified an xjet to become a softwash xjet

That's clever. So did you unthread the variable nozzle and put a 1/4 coupler on there? If so, what are the thread size and type you needed to adapt to? I tested my mjet with the #14 size orifice drilled out and I'm still drawing about 4 to 1. The pressure and atomization are slightly less but not what I'd classify as "soft washing". I remember reading somebody doing this before and I wish I had done it sooner myself. I guess tomorrow I will play around with the jrod in tandem idea.
