Inquiry (采购产品): pressure regulation We've recently acquired a pressure washer model Niagara 4505G-4E; ser. 8358203 and was interested in keeping the max. pressure below 3000#. What methods are available to control this. It has a Giant pump model P455 driven by a Kohler motor model CH 20. Any help would be appreciated.
