Does anybody wash decks with a 8 gpm 3000 psi machine or is it to much volume? reason why I ask is I am currenlt using a 5 gpm 3000 psi and I am looking to buy an 8gpm to mount in my van. Will I do damage to the deck with this kind of volume or would I have to ajust the unloader everytime I go from washing a house to a deck?
