House Wash / Roof Pump Life Expectancy

So I’m pretty new to using a soft-wash setup. I’ve been down-streaming houses for a couple years. More and more people are asking me to clean their roofs so I’m probably jumping into it this year but don’t have much of an idea about what to expect in terms of how long these pumps last. I mean… we down-stream cause having corrosive chemicals go thru the pump just ruins it… I’m assuming its going to do the same to these 12v pumps. How long should one last and what do you guys recommend?


Even if you go through a couple a year consider it the cost of doing business. they’re cheap considering how much money they make you.
