• Make sure the Prime valve is open to allow air to purge from the paint pump. • Make sure the inlet strainer is not clogged. Clean or replace the inlet strainer. • Make sure that the siphon/immersion tube is not loose. • Make sure the lower ball is not stuck. This could be due to insufficient cleaning and/or not leaving mineral spirits in the unit after flushing.
