Water Pump - 12V works, 110V blows a fuse
My water pump, Shurflo, in my 2007 Fleetwood (popup) blows a fuse (10A blade/inline fuse) when plugged into shore power but runs fine on 12V. Everything on 110V works fine, except the water pump. Th...

An RV battery delivers what, 12.4 - 12.5 volts under an 8-amp water pump pressure build-up.
The voltage difference 12.4 - 14.4 absorbsion limit is TWO FULL VOLTS. Divide 14.4 into 12.4
How much percentage GAIN is there with using higher voltage?
This deserves troubleshooting with an inductive ammeter. The pump may be sick.
Find the cause soon and perhaps the pump can be successfully repaired. Find it later and guaranteed a new pump will be required. After a waterless outing.
