How To Fix An Airless Sprayer That Is Not Priming.

What happens here

The presenter, Chris, the Idaho Painter, explains that airless sprayers commonly encounter priming issues. This happens when paint buildup, grass, leaves, or small rocks get past the rock guard and lodge in the lower fluid section, specifically around the tiny ball valve. When this ball valve is obstructed, the sprayer will attempt to prime but either no paint or very little paint will come out of the prime hose, preventing the sprayer from getting ready to paint.

Goal: Understand why an airless sprayer fails to prime.

And there's a little tiny ball inside there, and it could get hung up in the ball. And and what we see quite a bit is paint breaking free from this hose that eventually settles in this hose over time. And it builds up. It'll eventually break free. it'll try to pass that ball and it'll get stuck in that ball and and then the the sprayer itself won't prime. It'll just sit there and and attempt to prime and no paint or very little paint will come out of your prime hose and it won't prime and won't get ready to paint. So, quick quick and simple fix. And to determine whether that's the
