mlaurenza 14 Report post Posted January 2, 2010 Has anyone tried to convert a single gun pressure washer pump in to a dual gun system? If so how? Do I need 2 unloader valves or can I just tee out of the one unloader valve that I have.... Share this post Link to post Share on other sites
offduty 25 Report post Posted January 2, 2010 To be productive you would need at least a 14 to 16 gpm pump to even start thinking about running two guns. It has been discussed here and at PT so I am sure a search will give you the technical info you need. Share this post Link to post Share on other sites
