I purchased another wash almost a year ago. It is running hypro 2400 series pumps I have replaced all seals as we been trying to upgrade this wash. I have one problem that seems to be a thorn in my side customers complaining "When are you going to turn the pressure up!"I was running them at 1100 psi which I do at other wash, however, I must admit I turned them up to 1400 psi with a 2505 tip and it doesnt seem to affect it at all. It just seems weak. Is there another tip I can use to help any ideas would be greatly appreciated!
