Water pump issue??

'06 Phenix

Very strange...pulled the coach out of storage with intent of draining fresh water tank to the grey. Fresh had about 50%. Turned on water pump and kitchen faucet. Ran ok for a few minutes then water stopped flowing; replaced by sound of air in the line, spitting out water.

Filled the tank to 80% and started again. Same thing happened at about 50% level.

What's going on? Thanks...

Yes, very strange.  Do you get the same result at all of the faucets?

are you going by the gauge or the amount of gallons to figure 80% Gauge may be wrong

Getting air on the supply side to the pump.

But why does it pump normally for a while, then quit?  Water outlet from tank to pump is on the bottom of the tank.  If there is a hole in the supply hose to pump, it should be visible as a constant leak due to hydrostatic pressure of water in tank.

And mine.  If your gauge is the Javalina system, the sensor or the calibration could be bad.  Visually verify the actual tank level if you can.

Thanks all. Headed to Nacogdoches tomorrow about another issue, so I'll bring it up then. Have never verified the water gauge, so we'll look at that for good measure.

We removed the "modesty" panels from the tank bays so that we can always have a quick and easy visual of the fresh tank, plumbing, etc.

Tank sensors are helpful, but nothing beats a quick and easy visual inspection.
