1600psi is probably rated through the smallest orfice. And Im certain theres losses up the pole and especially at the 180 turn. I’ll be using the largest orfice with the 3/16” hole that fans out. Its not stronger than the spray at a car wash. And cause the pole says RATED for 4000psi, its not magic. It doesnt boost the pressure. I designed industrial hydraulic systems and robotic waterjet cutting systems for 30 years so I little first hand
knowledge. Give me a tiny bit of credit. Im not spending $$$ on equipment to blow the crud off the gutter guards on my new 2nd home lake house cause I are stoopid

So I thought the review was still funny.
