The north side of our 3 story house needs to be sprayed with Spray and Walk Away. I need a way to shoot it all the way to the peak, which is about 40 feet. I've looked at trombone sprayers that shoot 30 feet, my pressure washer has a siphon function that will mix chemicals with the water but it only works with the low pressure nozzle - not gonna make it to 40 feet with that.
Any ideas of an inexpensive (less than $100) pump to spray that area?
