Why is my Liquid Controls Water Pump so noisy?
- EElijah ConwayAug 10, 2025
If your Liquid Controls Water Pump is noisy, it could be due to several reasons. One potential cause is cavitation due to poor suction conditions; you can address this by cleaning the inlet strainer or increasing the pipe size. Alternatively, the vanes might be sticking, requiring you to remove and clean them, checking the strainer for foreign material and replacing the vanes if they are swollen. Worn bearings could also be the culprit, necessitating replacement and monthly greasing. High differential pressure could be another cause, which can be resolved by checking for restrictions in the discharge line, ensuring the delivery hose isn't too small or long, and slowing down the pump. Lastly, PTO shaft vibration could be the issue, requiring inspection and repair of the driveline component.
