How to set up a Soft washing sytem

guys im confused… So Im getting a 150 gallon tank, for water ad 35 gallon tank for solution, and a 12v pump, so what is the correct set up? how to do connect the pump to the tank? and how do i Draw solution at the same time?

Do i downstream siphon from the chemical tank after the pump? or do I just mix everything in one tank and suck everything thru the pump?

12volt, one tank. Mix whst you want and it runs through the pump.

You may want a bigger mix tank I use roughly about 2 gal of mix per 100 sq ft unless real shallow pitch, then will be less. But most my homes are at least 8/12 if not steeper so get a little more runoff. I tend to use a little weaker solution(about 3%), so normally may have to hit bad areas more than once.

Be sure to run at least 5 gal, if not more, of water through your pump after you finish.
