    Soft wash pump replacement

    I have a soft wash business and recently burned out my booster pump - possibly due to the way I plumbed the inlet piping from the water & Chlorine tanks. I trying to determine the best option to replace the pump with for my operation.

    My equipment:

    6x12 single axle trailer
    60 gallon water tank
    120 gallon Chlorine tank,
    1hp Flint & walling single phase booster pump (broken)
    300' hose
    7000w generator 10500w starting/peak
    3500 psi, 4gpm pressure washer w/honda gx390 engine
    200' 5000psi hose

    I hook up with water supply on site, fill the 60 gallon tank, and keep it full while working. Water comes out the 60gallon thank into the booster pump. Chlorine & detergent are also feed into the booster pump. The Chlorine-water ratio is controlled by ball valves at the inlet of the booset pump. When it works, I get about 170psi out the nozzle and can hit the peak of a 2 story house from standing on the driveway. The nozzle allows me to spray or mist depending on how far I move the trigger.

    It has worked great. Downside is a lot of running to switch from Chlorine to fresh water and the possibility of damaging the pump due to low water flow into the pump or by a build up of pressure if the trigger on the house is not pulled.

    The booster pump is tost, really just the motor. Should I replace with the same or is there another option? If I go this route again I'm going to install a flow protector and a 260psi pressure relief valve.

    This pump is about $500 and looking at $800 with the additions.

    I need the psi for houses since I don't just stick to roofs.

    I would appreciate any info and help you could provide. thanks.

    most likely that booster pump your running is not rated for chemicals... I would maybe look into replacing it with 12v roof cleaning pump? maybe a fatboy or pentaflex? You won't get 120psi out of them, but you will get 7 gpm and will easily be able to spray over 2 stories with the correct nozzle setup.. As for switching back and forth to water? I would assume that is for rinsing after applying?? Do this.. If its a 2 man crew, use the 12v pump to apply the chems mix to houses and use the 4gpm unit and the correct tips for rinsing with.. You will fly through it since there is no switching back and forth... Hopefully that will help you out a bit.. Most guys run the booster pump to aid in rinsing only, and that is usually because they do not have a pressure washer on board..

    FYI.. this is the method we use to apply chems to houses and it works great for us.. With no wind we can clean 3 stories from the ground.. should last a bit longer also..

    I run solo, wash & rinse 1 side at a time, keep the Chlorine from drying on the windows. Lots of back & forth. I only have one hose reel for the softwash. I would hate to run dual hoses to wash & rinse. I would rather switch back and forth at the pump.

    Also, with the water tank I can dilute the Chlorine to aid in application
