What to do if Landa Pressure Washer pump runs extremely rough, pressure very low?
- DDebra GreenAug 19, 2025
If your Landa Pressure Washer pump runs extremely rough and the pressure is very low, it could be due to a restricted inlet or air entering the inlet plumbing. Ensure you have properly sized inlet plumbing and check for an airtight seal. It may also be caused by inlet restrictions and/or air leaks, or a stuck inlet or discharge valve. Replace any worn cups and clean out any foreign material. Also, replace any worn valves.
