I recently acquired an 18hp gear driven 15gpm pump for roof cleaning. My question is: how do you plumb these systems so the constant agitation from the bypass hose doesnt cause your tank to foam over with the surfactant? I havent tried it yet, but it seems like it would cause a huge amount of suds to grow out of the tank if you had any amount of time in bypass? (trigger gun closed) I was wondering if people downstream the surfactant and just mix the SH and Water in the tank? Thanks in advance!
