Water Pump Not Pulling from Water Tank? -

Ahh, the wisdom of Furpod lives on.  Thanks for staying on this forum Mark and for helping so many of us.

Yes.. but it will take a couple minutes.. during which time you will get.. just air out of the faucets.


Something to try.. you know where the valve and the anti freeze take up hose are. Fill a clean container with water, and put the AF hose into it, set the valve to take up from there, and turn on the pump.
This will prove the pump itself is operating properly, and, prime the pump partly.

Thanks Mike.  I'm grasping at straws.  If there was a clog at the outlet of the tank itself the pump wouldn't be pumping air -- it would be trying to create a vacuum between the tank and the pump -- no air being pushed out of the faucet. 

The OP says he's checked all the way back from the pump; I'd think any breaks would be apparent.  I guess it could be a bad pump.  The vanes of the pump could be loose on their axle; the motor would run but the vanes wouldn't turn, so it might sound like it's working but isn't.  That doesn't account for air coming out of the faucet though.

Furpod's idea to blow back from the inlet hose of the pump would probably my next step.

Like Furpod I'm circling back around.  One of the things this really sounds like is the valve on antifeeze siphon hose is open.  That valve switches the pump from sucking water from the FW tank to sucking up antifreeze -- if the end of the hose is stuck down in a jug of antifreeze.  If there's no jug, the hose will suck air and pump it to the kitchen faucet.  If there's any doubt in your mind whether you found the right hose/valve, let us know and we'll help figure that out.

Otherwise, it sounds like a really odd problem.  If air is being sucked in from somewhere other than the antifreeze hose you might be able to hear where.  I'm a little surprised if the hose is broken or disconnected at some point between the FW tank and the pump that water isn't flowing out of the tank by gravity.

I just thought of something maybe Furpod or someone else can help with.  There is a check valve between the city water input and the FW tank.  It prevents the FW tank from filling when you're hooked up to city water.  Maybe that's stuck in a way that the pump is pumping air from the city water input on the outside of the trailer.  Maybe the valve was installed backwards...  Just guessing.

We have traced the line and no kinks. The only thing I can think of since we can hear air coming out of the faucet is a air leak somewhere. When we checked the silver filter it had no water in it at all. This is the first time we have tried to use it and it is brand new.
