So I'm getting ready to paint my house and I pull out my airless (graco magnum x5- worth every penny btw) and it won't prime. I download the manual and discover that there are exactly 8 pages of "don't try this at home" before the sprayer is even talked about. Seriously? Wtf? And all that was wrong was a ball valve stuck.
At least you figured it out. I get all "why me lord?" When stuff goes wrong. I did find cussing helps fix stuff. Lol
Rofl. I took that thing APART. And then realized I didn't have to when I found the problem. Oh well. I've got my money's worth many times over. I had to unstick the ball valve, add a .25 o ring I destroyed and install a new 517 tip. It's ready to go now.
If you hadn't taken it all apart, you wouldn't have found the problem. Sometimes that's just how it goes. Next time will be easier.
