2FW tanks in 05 Safari??

[Del Gurney]

Hi folks:
I've been wondering why I go through water so fast!
So while investigating a hot water leak I discovered a fresh water tank under the floor surrounded by styrofoam for insulation. (I though I was sucking from the under-carrage tank)
So I ran that tank down to empty (red lights flashing in galley) and the pump took off so shut'r off right away. Looked under AS and FW tank bulging full!!
I can see the sensor is on inside tank.
I can see that the fitting leading to the FW pump (inside tank) is a 2 way fitting with one of those clear un-reinforced heading out the wheel well (and presumably to the lower tank)
This ain't right. How is this supposed to be plumbed?? B-jezz's it's a tight fit under there!! I'll need an Octopus that's Pex savvy.
Lil help pls.
Thanks

Before you say your fresh water tank is bulging full... drain your gray water. If your pump runs and runs and runs - the fresh water is EMPTY. I don't care what the sensors say. Unless you have a sewer line hooked up and your gray tank drain valve open, that's where all your fresh water went.

BTW I have a 2005 Safari 25 FB with a 30 gallon fresh water tank - three longish showers and wash dishes twice and it's sucking empty... and the gray tank is full. I DO move water to the black tank by plugging the shower drain, and using a pump to put the water left in the pan into the toilet which has a dowel rod holding the drain slightly ajar.

Betcha money it's your gray that is full. Your owner's manual will show you the locations of your tanks. BTW some of the smaller units have a combined gray/black tank, so hook up the slinky and feed it into a sewer cleanout before you pop that drain valve!

Best of luck Paula
