Why is the pressure fluctuating on my Shark Pressure Washer?
- JJessica SandovalAug 26, 2025
If the pressure is fluctuating on your Shark Pressure Washer, the issue could be due to worn valves, a blockage in the valve, or the pump sucking air. Check the water supply and look for air seepage at joints in the suction line. Another potential cause is worn piston packing, which should be inspected and replaced if necessary. Additionally, if you are using a gasoline engine at altitudes above 1000 ft above sea level, it may be necessary to install a high altitude main jet in the carburetor. Contact your local authorized engine sales and service center for details.
