Axial Pump Assembly
The internal unloader valve or check valves have likely failed or stuck in the bypass position. This prevents the reciprocating pistons from building the necessary kinetic energy in the water stream. Replacing the pump assembly restores the hydraulic seal and pressure regulation capacity.

Water Inlet Filter
Debris accumulation on the mesh screen restricts the volume of water entering the pump manifold. This restriction causes the pump to starve for fluid, resulting in a loss of output pressure. A clean filter ensures a consistent, non-aerated water supply for the high-pressure stage.

O-Ring Seal Kit
Degraded seals at the intake or high-pressure coupling allow air to enter the system, leading to cavitation. Because air is compressible and water is not, the presence of air in the pump chamber prevents the pistons from generating high-velocity discharge. New seals ensure an airtight fluid path.
