no water at all. took hose off the head and nuthin! The nozzle at the end of hose threw housing does clog with a grain of sand(piece of shell) so im familiar with that and yes the oil is a quick fix by just running premix. but the electric scensor?? will it be ok just hanging disconnected or do I have to connect the 2 wires?
I would try connecting the 2 wires. On the water pump, does the impeller have a key to rotate it from the drive shaft? It may have slipped or sheared.
