WHAT NEXT????

I just pulled the grill off of the furnace and the line that goes to the fresh water tank goes under the floor and I cannot see it.

it looks as though my fresh water tank is just in front of the wheels and my drain is right behind the left front wheel.

When you have the valve switched to the tank is there any suction on the antifreeze pick up? Maybe the valve isn't sealing completely.

Is anyone else having a problem with the site?  It is telling me that I have exceeded the number of posts allowed and spamming is not allowed.  Go figure I would have a problem!!

Ok, here is day 2.  I took the elbow off the line that goes to the fresh water tank just before the wall.  I was able to blow through the line.  I took the line off from the antifreeze/fresh water tank valve to the elbow in the line before it goes through the wall.  I tried to blow through the line and could not.  I took the elbow off and the line was clear, but the elbow had pieces of plastic stuck in it.  I cleaned those out and put the line and elbow back on to the line to the tank.  I was able to blow through to the tank.  Filled the fresh water tank and hooked hose up to city water  connection to make sure that air was out of the lines.  Disconnected the hose.  Went in 5ver and turned pump on.  Pump came on and ran for a couple seconds and shut off.  Turned water on at kitchen sink had water and the pump came on, good flow.  I figured that I would let it run for a little bit and flush things out (ran about 5 min).  Wrong, the pump now started to make a loud noise and vibrates the whole 5ver.  Before you could hardly hear the pump run inside.  Water flow has stopped.  It now cannot even pull water in from the winterizing valve.
