What happens here
After connecting all hoses and the spray gun, but before starting the pressure washer, open the water supply and squeeze the spray gun trigger. Allow water to flow through the system until all air is purged from the line and a steady stream of water is visible. This prevents the pump from struggling to prime itself with air, which can cause damage and inconsistent pressure.
Goal: Before starting the pressure washer, run water through the system to eliminate all air from the lines, preventing pump damage and ensuring proper function.
