My Pressure Washer is capable of 3000 psi at 3gpm. After four years of homeowner use, it has begun to behave poorly. When I start the machine, the pump only produces about 500 psi. The engine runs strong but is clearly not under load. After about 5 minutes of operation, the pump will suddenly kick up to full power (about 2800 psi). Here is a picture of the Comet pump with one cap removed.
