We are running 250 ft of 1/4 hose. We have it set for 3000 psi but by the time it travels to the tip we are getting 2000-2200. At this psi you can rip of the pin stripping if it has just been done. You can go as low as 1500 psi but it makes it tough to remove bird poo that has been baked on from the sun of froze to the hood. 2000-2200 works perfect
