Hey guys, I am planning on building a soft-wash system and had a few questions. I’ve been researching them a lot on youtube, this forum, and elsewhere, but I find myself getting overwhelmed with information and wanted to ask a few straight-forward questions and get straight-forward answers from people with experience.
My 8 gpm machine rocks for rinsing, but I find I often have to do multiple passes when down-streaming compared to, say, my old 4 gpm, which put out a strong enough mix that 1 pass was almost always good enough. I am building a 12v therefore as my go-to soaping machine, for roofs, stucco, and whatever else I want to wash, and for the general utility of being able to meter out SH and water at whatever % I please. I plan on using it to bleach houses and then using the 8 gpm to rinse.
A few of the concerns I have:
-Here in my somewhat rural area, we’ve got some taller homes in the middle of high-wind fields. Will the 7 gpm delavan 12v pump I plan on buying still be useful in windy conditions? Will it reach high peaks reliably?
-I have seen mixed opinions on going with the 7 gpm vs the 5.5 gpm. I figured I would go with the 7 gpm for the increased PSI, which I assume will help me reach heights easier. Would the 5.5 have as much reach?
-I have heard that the 7 gpm’s increased electrical draw has higher risk of electrical failures. What kind of failures are we talking about?
Thanks for any input!
