Yes, the pumps we offer can operate effectively in dirty water, even when it contains leaves, rocks, and mud. Since floodwater often carries sediment and debris, it’s recommended to fit the upstream end of the suction hose with a mesh to prevent debris from entering the pump system. It’s also advisable to choose a water pumping point with minimal mud and solid particle concentration. Furthermore, using 1-2 filters, depending on the location, is recommended.
