I have a FatBoy Pump with the "Pump in a Box" upgrade from Bob at PressureTek for sale. Used about 3 hours. Nice pump, not what I'm looking for. Paid: $342.90 Asking: $250.00
I think the key to using the Fatboy is the accumulator tank, 1/2" line, and smaller nozzles. Right now I'm using 10gpm nozzles. I'll probably have to go to bigger ones as the weather gets hotter. I cleaned a fence that's in real bad condition (peeling paint) using a 2505 nozzle yesterday. I knocked a little paint off rinsing but none washing. The owner was trying to make his problem my problem, but he didn't want to pay any extra for knocking off all the loose paint. I told him before hand that all he was going to get was a clean fence that still needs a lot of scraping before painting. I don;t think he believed me. lol!
When I have to go to bigger nozzles, I think I'm going to go to a 3/8" chem line. Well, at least I'm going to test a 3/8" to see if it works well. I don't see why it won't.
