Trouble Shooting Airless Paint Sprayers

What happens here

After removing the lower intake section, John uses a small pair of needle-nose pliers to carefully reach into the piston housing and extract the ball valve. He successfully pulls out a significant piece of dried, skimmed paint that was obstructing the ball's movement. This hardened paint film had prevented the ball from seating properly, causing the loss of prime. John then takes the ball and its housing to a sink and thoroughly cleans them with water, ensuring all paint residue is removed. During the cleaning, he also reassembles the small ball valve components within the lower intake section.

Goal: Remove the obstruction from the ball valve and thoroughly clean the components.

we're gonna begin the process of checking this ball and this is our lower in section right here we're gonna have a ball seat down here we're just going to remove this and one of the nice things about these sprayers is a lot of the times you don't need any tools we haven't took in this one apart so from the factory it might be really tight but typically we could just grab and use our hands to untighten everything and then we just tighten it back up with our hands so we don't need to go grab a whole lot of tools to look at this and repair this but here we go we've got the sprayer right here and we're gonna test it out to see if it's hand tight or not and it looks like it is in height sitting a little knot right there I mean that's like all fit I don't know I mean you call that it looks like so you're just gonna wiggle it and so John's wiggling it and he's got it took it off right there and now the first thing we're gonna do down inside here I'm gonna look inside this tube and a lot of times this is more less a brand new sprayer and we've only used it you know it's been used for a few weeks so I wouldn't think there would be a lot of paint buildup film but a lot of times if this is an older spare a couple years old there might be a big chunk of paint film and you'll see it inside there and you can grab it and just pull it right out I don't see anything I'm just gonna take and dump this and check to see if I see anything up in there and I don't see anything up there I'm going to just clean this back up right here because this is gonna end up going back on there so I make sure it's nice and clean before you put it back on there did you see anything up inside I think found our culprit gave me that John just thinks he's found something that's how simple it could be sometimes sometimes it's really fast and simple I would say most of the time it's as simple as pulling this thing off looking up there and you're gonna see some in a lot of times John he carries a tool belt or a bag I used to wear a bag tool bag a lot but because of the video and all that stuff I'm not doing it as much but I always had a pair of tweezers in mind because you can just reach up there with the tweezers or I had a small pair of small needlenose here's the hole you can't get both fingers up there and say grab a blade of grass and so John has found something let's see what you've found John do we want to try to zoom in here let me it's right I'm gonna get a little zoom in here and show you…
