jeffoExplorerOct 28, 2014Water Pump Ran DryI drained my fresh water tank and forgot to turn off the pump. Might have ran dry for almost a day before I found it. It still pumps but I was wondering how much damage I did.
Old-BiscuitExplorer IIIOct 28, 2014None.They are a diaphragm pump.Diaphragms move very little----1/8" travelThey do not rely on water for cooling or lubricationLook up mfg. and they will state 'designed to run dry' or similar
