I picked up a cheap used pw from craigslist yesterday that wouldn't pressurize. everything turns and the seals and the plungers look fine, but I'm confused by the plumbing. on the left hp outlet is the unloader which dumps down into the inlet which makes sense. but on the right hp outlet is another hose that goes down to the inlet as well. isn't this just dumping some of the pressurized water down into the inlet? is it some kind of burst disc that has failed? I took the fitting off and it looks like it has some kind of valve but i can force air through it no problem with just my lungs.
