Also, what is the quantity of water delivered? I need to spray my one story roof from the ground because of my age. Only need to spray about 10-15 feet forward of the gutter. Purpose is to remove small spots of black algae. Commercial firms want $225 to do the job!
The Chapin Slide Pump Sprayer works by you creating the pressure yourself in your hands as you slide the pump back and forth. The back end of the hose is weighted to drop into any container or bucket you may have water or solution in to pull through the sprayer as you pump. The sprayer can reach around 30 feet so it should be more than adequate to reach your treatment areas. The narrow spray will last only a few seconds since this is not a tank that is building up pressure, but rather being created with each pump of the sprayer wand. You can click on the overview video on the product page that shows how to assemble and use it so you can see how the spray comes out and what you would need to do.
