FW tank pump works - but no water

[GaryNK]

The switch(es) are another strange combination but for now, I have water in the tank and the system has worked fine. For some reason now, the pump runs but I'm not getting any water. Yes I have water in the tank.

Check to make sure the lines are tight at the pump. The pump "sucks" water from the tank. Any "leak" into the line will act as a siphon break not allowing it to draw water from the tank. Lines jiggle around as you drive down the road. Just a thought.

Thanks, That's a start.

Make sure your valves are all fully in the normal position.

thanks
I still don't like the switch configuration.

Also check the sediment filter near the pump. It doesn't take much sediment in that screen to block flow and not get water at the faucet. While you're at it, ensure the seals and connections there are good too and make sure it's not cracked (could it have frozen?) It's another place where air can be introduced and inhibit the pump's ability to pull water up from the tank.
