Remove, Inspect, and Clean the Stuck Ball Valve
At 5:11 in
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.
