What to do if my Echo MS-41BPD Paint Sprayer has no pressure?
If you experience little or no resistance during repeated pumping, resulting in no pressure, it could be due to a damaged, worn, or dirty upper valve plate, in which case you should clean or replace the valve plate. Another potential cause is a worn piston collar or piston cylinder assembly, which requires replacing the piston/diaphragm assembly.
